10 Things All Senior Pets Need

We see lots of senior pets in practice. Here are a few pointers you can share with your clients!

1) Good Nutrition– all senior pets need a diet that is tailored to keeping them healthy. All foods are not created equal. You must talk to your veterinarian about which diet is best for your pet. For example, a dog with early kidney disease should be on a lower protein diet. A dog with constipation issues may need more fiber. Less active dogs may need a senior food with lower calorie content.

2) A Good Quality Bed– a nice supportive bed to lay on is beneficial to their joints and muscles as they age. While they may prefer to rest on the cool tile, having a bed available to them is important. Crib mattresses make great dog beds (they can’t be soiled, they have plenty of room, and they have great orthopedic support)!

3) A Daily Walk– most dogs benefit from daily walks. Just to get out and stretch their legs and move around helps with mobility longer term. Nothing rigorous is necessary. Just getting out for a walk is good for body and mind and is special bonding time between dog and owner. Many senior pets will just sleep all day, so getting them up for that walk helps to keep them mobile. If your pet can’t walk for some reason or tires quickly, consider taking them out for a “stroll” instead or when they get tired! If they are not used to going for walks, start small. A walk down to the end of the sidewalk or block may be a good place to start until you know their limits. Never go out when it is too hot. Older dogs overheat more easily and may exert themselves more.

4) A Weekly Massage– gently massaging your dogs legs and back muscles has many benefits. Increased blood flow, anti-inflammatory effects, endorphin release, and stimulation of the immune system are just a few of the benefits this can provide. Daily is great, but even once a week is helpful. Who doesn’t love a massage?!

5) Joint Supplements– glucosamine is used to protect joint cartilage and helps to prevent progression of arthritis. Even though it may be difficult to see direct evidence of the benefit of joint supplements in some cases, it can help the joints and may help with longer term mobility.

6) Routine Grooming– Pets still need routine grooming and care as they age, and sometimes more often.  When they are routinely groomed, they feel better. If it is too stressful to take them to the groomer, consider having the groomer come to you (mobile service).

7) First Dibs– If you have a senior pet, there is a good chance you may also have a younger dog in the house. While the youngster may try to be dominant, allow the older pet to get first dibs. Let them be first to have their food bowl put down, first to have their leash put on, first for their treat, etc.

8) Good Oral Care– as pets age, we tend to be more reluctant about upkeep on the teeth.  Disease often starts in the mouth. Bacteria and chronic gingivitis are a bad combination and can lead to heart disease, kidney disease, or other systemic illness as the bacteria gets seeded into the bloodstream. Continue to have routine dentals as long as your pet is healthy and your veterinarian recommends doing so. Brushing, appropriate dental-friendly treats, and sometimes oral rinses can help in keeping the gums healthy.

9) Ramp for bed or couch, minimize stairs– We see a lot of injuries in the clinic of older dogs who jump off the bed or couch and cause serious injury to one of their legs or their back. Getting them used to some stairs or ramp up to these areas can be a great way for them to keep their independence and avoid injury. For arthritic dogs, use a baby gate to keep them from going up and down the stairs multiple times a day if you have stairs in your home.

10) Extra TLC– We all get busy in life. Take that extra few minutes when you can to really spend it with your pets. Look at them, talk to them, play with them, pet them. These may seem like obvious things, but in many households, things get hectic and time gets away. If a new pet comes into the household, make sure to give the same or more attention to your senior pet. Often when a new dog or puppy comes into the house, the older dogs get left out. Be aware and take extra care! We already know our pets don’t live as long as we wish they would, so don’t take that time with them for granted.

What in the World is Canine Influenza?

zoemask

There is currently a severe outbreak of Canine Influenza Virus (CIV) in the Chicago area, on the brink of being an epidemic, which you may have seen in the news. The disease has caused more than a thousand cases and the death of at least 5 dogs from January through March (as reported by the Chicago Tribune). Chicago Tribune: Canine Influenza Article and Video

Canine flu is not as common as many other viruses in dogs that you are used to hearing about. So, what is it?

  • It is a virus and a contagious respiratory disease that has affected thousands of dogs in the United States. It is a relatively new virus, which is why you may not have heard much about it. Remember the outbreak in Florida racing greyhounds with a new respiratory disease in 2004? That was Canine Influenza Virus. Then in 2005, outbreaks began occurring in boarding facilities and others involving pet dogs throughout the nation. It is thought that it may have gotten started in the greyhounds due to the mutation of the equine flu virus and exposing those greyhounds in the racetrack environment.
  • It does not appear to be contagious to humans, or at least no cases have been reported of CIV in humans.
  • Because it is a virus, there is no specific treatment, other than supportive care and treatment for secondary bacterial infections (similar to treatment of the flu in humans).
  • It is one of the viral causes of infectious tracheobronchitis (kennel cough).
  • Symptoms include coughing, sneezing, sometimes a fever, runny nose with eventual mucopurulent discharge, tachypnea/breathing harder than normal, decreased appetite, and lethargy or depression. Some dogs may also have sub-clinical infection and never show symptoms.
  • Most dogs fight the infection between 1-3 weeks. Hospitalization is required for development of pneumonia, high fever, or other issues.
  • Dogs with CIV should be kept isolated from other dogs for 2 weeks.
  • Dogs may shed the virus even before clinical symptoms start, meaning they may have already exposed other dogs to the virus before they are acting sick.
  • Veterinarians and technicians/hospital workers should wear protective clothing, including gowns and gloves, when caring for infected dogs. Hand-washing is always one of the most important ways to prevent spread of any disease.

In general CIV is very treatable and dogs typically recover when they are diagnosed and treated as quickly as possible. In immune-compromised animals, the disease is more serious as the immune system has a harder time fighting the virus and these animals are more susceptible to pneumonia and other complicating factors. There is a vaccine available. Although not a core vaccine, it should be considered for higher risk pets (boarding, going to the dog park, or traveling to areas with outbreaks or higher incidence of the disease).

Core Vaccines and In-house Antibody Titer Testing

In the news recently, the debate about vaccinations for children was at the forefront during the measles outbreak. There has been a similar debate going on in the veterinary community about vaccines for pets. Clients are electing not to vaccinate their pets or are inquiring about why they should, and if they really need to vaccinate their pets every 3 years? What is the appropriate and recommended protocol? Are we currently over-vaccinating?

chihuahua and syringe

In 2011, the American Animal Hospital Association (AAHA) recommended that ALL of the core vaccines go to a 3-year protocol while also stating that “among healthy dogs, all commercially available (core) vaccines are expected to induce a sustained protective immune response lasting at least 5 years.”  Many clients and professionals will still argue that an every 3-year protocol is still over-vaccinating and in fact most adult animals will have lifelong immunity without the need for repeated vaccination. Should we go to a 5 year or longer protocol for the DHPP and FVRCP vaccines?

The issue is that the immune system of every pet is different. How can we be sure our pet patients are protected? How can both sides of the argument be satisfied? One solution on the forefront is antibody titer testing. In lieu of a vaccination, a small blood sample can be taken and a “titer” test can be performed. This titer test will essentially say if this pet still has enough circulating antibody against a particular disease (canine parvo, distemper, etc.) In the past this has been very expensive to perform and samples had to be sent to an outside lab with results taking several days to come back. Now in-house testing kits are available to veterinary clinics and results in as few as 20 minutes.

Antibody Testing Kits For Veterinary Clinics 

Guide to Vaccine Antibody Testing

For owners who have concerns about routine vaccination,  a vaccine titer is a reasonable recommendation, and it may be that in the future this becomes a standard of care. Now that in-house fast titer testing is becoming available, it makes it more cost effective for clinics and for clients.

Lastly, one size does not fit all. The vaccine needs for our pet patients should be assessed yearly and the vaccination protocol should be modified as needed based on that pet’s risk, lifestyle, age, health, medical conditions, and travel as concurs with the recommendations of the AAHA task force.

Case Study Quiz: Hypertension and Neurologic Presentation

A 10-year old Golden Retriever presents with a history of unsteady gait. The owner reports she is walking like she is drunk and she has vomited a few times. You are taking a history in the room and notice her tilting her head to the left. Upon closer look at her face you see that her eyes are moving side to side rapidly. The veterinarian asks you to perform a blood pressure. The blood pressure is 200/120 mmHg. Answer the quiz questions, then scroll to the bottom for the answer explanations.

headtiltgolden

1) What medication may help to treat hypertension (high blood pressure) in this dog?

a) Benazepril
b) Prednisone
c) Phenobarbital
d) Furosemide

2) The condition from which this dog is suffering is also known as which of the following?

a) Vasculitis
b) Vestibular syndrome
c) Disseminated Intravascular Coagulation (DIC)
d) Syncope

3) Which cranial nerve is likely involved in this process?

a) cranial nerve III (oculomotor)
b) cranial nerve VII (facial)
c) cranial nerve VIII (vestibulocochlear)
d) cranial nerve V (trigeminal)

4) Which endocrine disease is often associated with hypertension?

a) Cushing’s disease
b) Addison’s disease
c) Diabetes mellitus
d) Hypothyroidism

5) The eyes moving side to side rapidly is also known as:

a) Vertigo
b) Nystagmus
c) Postural thrust
d) Bupthalmous

Answers: This dog is exhibiting symptoms of vestibular syndrome, which has many possible causes. Because this dog has a very high blood pressure (should be less than 150 systolic in a nervous dog), the likely cause is a vascular accident (a stroke type of event).

Hypertension can be sometimes be associated with Cushing’s syndrome in dogs, and with hyperthyroidism in cats. Hypertension in dogs may be treated with benazepril and/or amlodipine. Amlodipine is the treatment of choice for cats.

Vestibular syndrome is a results of the inflammation or disturbance of cranial nerve VIII (8), the vestibulocochlear nerve which helps with sound in the ear and with equilibrium (balance). Dogs that have vestibular syndrome are often  nauseated and have a history of vomiting. The eyes moving back and forth or side to side is also known as a nystagmus.

Rabies Exposure Guidelines: New Study from JAVMA

It isn’t all that uncommon. A client has a dog that has been bitten or exposed to a rabies “suspect.” Whether it be a fox, a skunk, coyote, or bat, any wild animal could be a potential hazard for transmitting rabies to our domesticated pets.

State law is very strict regarding pets and exposure to rabies. There was a story in October 2014 that raised some controversy over this issue. A 10-year old Schnauzer was bit by a rabid skunk. The dog’s rabies vaccine had only expired 10 days prior to the attack. The options were to euthanize the dog, or quarantine for 3 months in a kennel with then another 3 months of strict home confinement. The owner was devastated but ultimately chose euthanasia.

For currently vaccinated pets exposed to rabies, they must receive a rabies booster immediately and then be under home confinement for 45 days.

As we know, there is a very high chance that even if the rabies vaccine has lapsed, the animal likely still has immunity. This is why this case is so heartbreaking.

A new JAVMA study, published for January 15, 2015 looks at a Comparison of anamnestic responses to rabies vaccination in dogs and cats with current and out-of-date vaccination status.

Full Abstract Here

 

Findings in this study “supported immediate booster vaccination followed by observation for 45 days of dogs and cats with an out-of-date vaccination status that are exposed to rabies, as is the current practice for dogs and cats with current vaccination status.” 

This is important information to keep in mind for pets that have been vaccinated and exposed to rabies, even if their vaccine has recently expired. While state law will still be in effect, this can provide some additional information to pet owners who find themselves in this predicament.

a)      Six

b)      Four

c)      Zero

d)     One

e)      Two

ANSWERS AND EXPLANATIONS TO QUESTIONS:

Question 1: Correct answer: D

Bacteria are referred to as prokaryotes because they lack a true membrane-bound nucleus. Animals, as well as all multi-cellular organisms, are known as eukaryotes since they have a membrane-bound nucleus. Bacteria do have ribonucleic acids, and several antibiotics target transcription of mRNA. Bacteria are able to metabolize glucose. The type of cell wall that a bacterium has helps us differentiate whether it is a Gram-positive or Gram-negative organism.

Question 2: Correct answer: D

Demodex is the cigar-shaped mite. The other mites are much rounder. The generalized skin lesions are not specific for Demodex as they can also be seen with Sarcoptes.

Question 3: Correct answer: A

When inflating the lungs, the pressure should reach but not exceed 20 cm H2O.
Question 4: Correct answer: D

Red bag is the layman’s term for premature separation of the chorioallantois from the placenta and is a medical emergency. The chorioallantois interfaces with the mare’s endometrium and is the interface that transfers oxygen to the fetus. Under normal circumstances, the fetus breaks through the chorioallantois at the cervical star, and the fetus and amniotic sac are delivered first. In a red bag delivery, the entire fetal-placental unit is being delivered all at once and thus can cut off the oxygen supply to the fetus prior to birth; this can result in death of the fetus if parturition is not facilitated immediately.

Question 5: Correct answer: C

Cows have non-seasonal polyestrous cycles. This means that they have estrus cycles year round. Average estrus is 21 days and lasts for 18 to 24 hours, but heat stress can shorten this window. Estrus is the time of “standing heat” when the cow will stand to be mounted by the bull. Sheep are polyestrous in the fall. Cats are induced ovulators.

Question 6: Correct answer: C

Goats have no upper front teeth (incisors); their upper front mouth is one big gumline. In the back on their mouth they do have both upper and lower teeth. Goats are born with teeth which are replaced by permanent teeth as they age.
The dental formula for permanent teeth in the goat is:
2 ( I 0/3 C 0/1 P 3/3 M 3/3) = 32

Ebola Virus and Animals

As animal lovers, I think all of us that read about Spanish Ebola patient Teresa Romero‘s dog “Excalibur” being euthanized as a precaution from exposure to Ebola were disheartened. In the veterinary community, our pets are our family members. This disease has caused a lot of fear. I know we were all relieved that they decided to quarantine the U.S. Ebola patient Nina Pham’s dog Bentley for monitoring instead of euthanizing him as a precaution, and were happy to hear he is now safe at home.

There is not a confirmed source for Ebola currently, but is thought to be found in fruit bat populations. Humans initially may contract the disease by coming into contact with an infected animal (bat or primate) or infected fruit or meat (bushmeat), and then human to human transmission occurs via bodily fluids or fomites with infected fluid. Those caring for Ebola patients or in close contact are at highest risk.

In the current Ebola outbreak in West Africa, animals have not been found to be a factor in ongoing transmission. According to the Centers for Disease Control, the USDA, and the AVMA, pets are not considered to be at a significant risk for Ebola in the United States. This is probably because currently it is still considered low-risk for humans in the U.S. as well, so would be even lower risk for pets. But even in West Africa where Ebola is found, there are no current reports of dogs or cats actually becoming ill from Ebola. That being said, the above organizations are continuing to work to gather more information about Ebola and animals for veterinarians and the public.

There was a study written regarding the outbreak of Ebola in Gabon in 2001-2002. Over 400 dogs were screened for Ebola antibodies (many dogs were thought to have eaten infected dead animals because in this country dogs are scavengers), and approximately 25% of the dogs had detectable Ebola virus- IgG. This shows that these dogs were exposed to the virus. However, none of these dogs were symptomatic. Therein seems to lie the concern then about dogs harboring and transmitting the virus, even if they are asymptomatic. But, the dogs with positive antibodies against the virus tested negative for the disease. So the question is, when they are initially exposed, how long could they be shedding virus if at all? Currently only a few animal species (primates and humans) have demonstrated the ability to actually spread the Ebola virus.

As a vet tech, if you were to be encountered with the rare situation that an owner believed their dog to have Ebola, the best thing to do would be to notify the veterinarian immediately. The veterinarian should take a thorough history, acquire personal protective equipment, quarantine the dog, and contact the CDC and state veterinarian.

Please visit www.avma.org/ebola which includes information for veterinarians and a FAQ section for clients. There is also a link to the CDC page regarding Ebola and pets. You may also listen to this podcast by Dr. Ron DeHaven, the VP and CEO of the American Veterinary Medical Association regarding Ebola and Pets.

Leptospirosis Review

October is Leptospirosis awareness month. Take a moment to review some facts about this zoonotic disease.

What is Leptospirosis? It is a disease caused by a spiral shaped Leptospira bacteria that can infect wildlife, domestic pets, and humans.  Many wildlife are carriers of the bacteria and do not have any clinical symptoms of the disease.

How is it transmitted? The bacteria are passed in the urine to water sources where they can live and reproduce. They can survive for a long time in water (especially stagnant water, ponds, or lakes) and wet soil. Animals become infected by drinking or swimming in water that is contaminated by the bacteria. It can enter the bloodstream through the mucous membranes or through a wound or cut.

Can it be prevented? Vaccinating dogs and livestock for leptospirosis is an important part of prevention, especially in areas where the disease is prevalent. Avoid stagnant water. Practice good hygiene and wash hands frequently- especially if there is contact that may have any urine on it.

What are the symptoms? The symptoms can resemble those of the flu virus. Fever, decreased appetite, vomiting, diarrhea, dehydration, weakness, and lethargy are some symptoms. Some dogs may have jaundice if the liver is severely affected. Bloodwork of a leptospirosis infected dog often has increased kidney and liver values. If a dog is suspected of having leptospirosis, make sure technicians handling the dog and the dog’s urine contaminated bedding, etc. wear gloves and protective clothing. The time between exposure and development of disease is usually 5 to 14 days, but can be as short as a few days or as long as 30 days or more. Cats seem to have some natural resistance and infection is rare in this species.

How is Leptospirosis treated? Treatment for leptospirosis involves supportive therapies including IV fluid diuresis and antibiotics. Leptospirosis is often treated with a combination of antibiotics including amoxicillin and doxycycline. The disease can be fatal, and the best chance for a good outcome is early diagnosis and treatment.

For more information about this disease, please visit www.leptospirosis.org and http://www.cdc.gov/leptospirosis/

Review on Eye Testing

Veterinary technicians commonly perform or assist with ophthalmic examinations. This blog is a review on common eye tests and normal values.

A good eye exam begins with a thorough history and appreciating a patient’s signalment (age, male/female/spay/neuter status, breed). Some particular breeds may be predisposed to certain ocular diseases. Taking a good history may help the veterinarian make a proper diagnosis and treatment plan.

Eye tests should be performed in a certain order. The proper order for the most common ocular tests are Schirmer Tear Test (STT), Fluorescein stain, and Intraocular pressures (IOP).

1)   Schirmer Tear Test- The STT tests for dry eye or kerratoconjunctivitis sicca (KCS). This is a decrease in tear production. A small piece of paper made for this test is inserted under the lower eyelid and held in place for 60 seconds. Normal tear production should be greater than 15 mm in 60 seconds. Most normal dogs will produce more tears than this but this is a guideline to follow.

036

039

2)   Fluorescein stain- This is a yellow dye which is applied to each eye to look for a corneal abrasion or ulcer. The abrasion or ulcer is seen when highlighting the stained eye with a fluorescent blue light.

034

035

3)   Intraocular pressure (IOP) – This is the test for glaucoma. Glaucoma is increased pressures in the eyes. The pressure in the eyes is tested using a device called a tonometer (the most commonly used one is the TonoPen). A drop of proparacaine is applied to each eye to numb the surface of the eye. The tonometer is gently touched to the surface of the eye and a proper or good reading should be with less than 5% error. Normal values are less than 20 mmHg (typical normal range 10-20 mmHg). Again, this is only a basic guideline and should be interpreted based on the rest of the exam and clinical signs. A low pressure may be due to uveitis (inflammation). It is important to note: DO NOT put any pressure around the neck region while holding the pet for IOP. This can falsely elevate the readings.
