Arthritis in your Aging Pet

by: Dr. Jo-Ann Liebe

dog_exercise_stairsArthritis, put simply, means “joint inflammation”.  Inflammation which we see after injury such as a cut in your skin or a broken bone is important for recovery and repair of tissue, but chronic, ongoing inflammation in and around joints can lead to degenerative changes that are harmful and permanent.  It is believed that 90% of cats over the age of 12 have some degree of arthritis and at least 20% of dogs over age 7 (that number increases depending on breed and history).

Why do these changes occur at all?  Sometimes the joint is just abnormal from birth.  This type is “congenital” which means “born with”.  An example of this is hip or elbow dysplasia.  If the cartilage, bones, ligaments and muscles do not fit together properly if will result in uneven wear and tear on the cartilage surface.  Cartilage decreases joint stress by reducing impact on the ends of the bones in the joints, like a gelantinous shock absorber.  When cartilage is damaged, a cascade of inflammatory changes occurs, eventually leading to destruction of cartilage and subsequent damage to underlying bone.  Cartilage contains no nerves – if your pet is showing any signs of pain the damage and changes in underlying bone have already begun.  Arthritis can also occur secondary to trauma – this can mean physical injury like torn ligaments, broken bones that are close to or involving the joint or some preventable kinds like increased wear and tear in athletic animals (including the flexibility of cats and their jumping ability) or secondary excessive weight bearing in obese animals.

What can you do about it?  Realize that arthritis can be prevented in some animals and reduced and slowed in others that are predisposed.  The final development of the joints in an adult animal are partially genetic and partially environmental.  You control the environment if you obtain your pet as a puppy/kitten.  The two main areas to control are nutrition and exercise.  Use a good-quality development food, in dogs be sure it is appropriate for your size of dog.  A puppy that will be over 25kg as an adult should be fed a large breed formulation.  Using a home prepared diet, incorrect diet or supplementing with incorrect amounts of calcium and phosphorous can lead to abnormal development.  Besides the right food you also need to feed the correct amount.  Excessive weight can be very damaging to growth plates so it is important to maintain a lean body weight.  The first few months of rapid growth are usually not a problem, but once growth slows at about 5 months of age, food should be reduced/adjusted to match requirements.  Learning body condition scoring and/or getting help from trained individuals at your veterinary hospital can help you keep your developing pet on the right track!

Exercise is the second important environmental factor you should control.  Hard surfaces like concrete and forced excessive running (jogging or running with a bike for example) can result in trauma to the cartilage and growth plates resulting in abnormal joints as an adult.  Growth plates can also be damaged when a puppy or kitten jumps down from high levels (like inside truck down to the ground (puppies) or off a high counter to the floor (kittens)).  This can result in a limb growing “crooked” because part of the growth plate is damaged and part keeps growing.  The best exercise for puppies is leash walking if on concrete and free running on soft ground.

Once your pet is full grown maintaining a lean body weight will help keep joints in good shape.  Use an appropriate diet as recommended by your veterinarian.  If your adult dog was born with conformational abnormalities that predispose him to arthritic changes then use supplements to support cartilage structure, suppress inflammation, and reduce the free-radical damage.  Supplements containing glucosamine, chondroitin, antioxidants, omega fatty acids are all known to be helpful.

The x-rays above show the progression of arthritis in a dog.  The good hip has only minor changes throughout the dog’s life.  The dysplastic hip has a small progression of arthritis until the dog turned 10.  A year and a half later the dog was having further issues with that hip, the x-rays showed a large change in the amount of arthritis in the hip.  With a specialized joint diet, supplements and an NSAID, this dog went on to live comfortably for 2 more years.

What are the signs of arthritis?

  • reluctance to take walks of usual length, decreased activity
  • stiffness (that may disappear once the pet has “warmed up”)
  • difficulty climbing stairs, climbing in the car
  • difficulty rising from rest
  • difficulty jumping up to surfaces that previously were not a problem, hesitancy in jumping
  • limping
  • abnormal gait (movement while walking or running)
  • licking of a single joint
  • acting withdrawn, spending less time playing with family (which is often misunderstood as a sign of aging)
  • soreness when touched
  • rarely, aggression when touched or approached
  • lapsed litterbox habits in cats (due to difficulty in getting in and out of the litter box)

Weight Loss

Weight management in older arthritic dogs is very important.  Joints that are already sore and stressed are made worse when they have to support extra weight.  And let’s face it – our pet population is battling obesity just like the human population.  The difference is, it is the HUMANS who are making the dogs obese.  Numerous studies have been done that show reducing weight leads to significant improvement in quality of life.  Ease of activities such as climbing stairs, jumping into a car or truck, and even getting up from a sitting position can improve dramatically with weight loss.

Just like in people, exercise is vital for weight loss.  Feeding less food alone simply decreases the resting metabolic rate.  Exercise increases the rate and thus burns more calories.  One of our goals is also to increase muscle mass.  Providing 20-60 mins a day of activity along with reduced calorie intake will help patients with osteoarthritis.

Veterinary Diets

Several veterinary diets have been introduced to the market specifically for dogs with osteoarthritis and more of these specialty veterinary diets are soon to follow.  These diets contain EPA (eicosapentaenoic acid) and/or DHA (dicisagexaebiuc acid) which result in less inflammation in the joints.  They also include glucosamine and chondroitin.  Some dogs show improvement being these diets in as little as three weeks!

Therapeutic Exercise

Controlled exercise is invaluable in treatment for patients with osteoarthritis.  This helps improve function, reduced pain, and the need for medication.

Initially, an exercise program should avoid overloading the joints.  Walking and swimming are excellent for starters.  Exercise programs must be tailored for each dog and your dog should not be forced to exercise during times of pain, as this will increase inflammation.

Controlled leash walking walking in water, jogging, swimming, and going up and down ramp inclines are excellent low impact exercises.  Exercise should be monitored so there is is no increased pain after the activity.  In the early phases, it is better to do three 10 minute sessions rather than one 30-minute session.  The exercise can be daily or every other day.  Walks should be brisk and purposeful, with minimal stopping.  Swimming and walking in water are some of the best activities for dogs.  The buoyancy of the water is significant and limits the impact on the joints while promoting muscle strength, tone, and joint motion.  Controlled exercise should not increase pain after activity.  If there is pain after an activity, the length of the activity should be decreased by half.  A 10-minute warm down period allows muscles to cool down.  A slower pace walk for 5 minutes will do.  Cold packs can be applied to painful joints for 15 minutes to control post-exercise inflammation.

Medications

Many inflammatory mediators and degradive enzymes are present in osteoarthritis and lead to the deterioration of articular cartilage.

Nonsteroidal anti-inflammatory drugs (NSAIDS) are important in the treatment of osteoarthritis.  They decrease inflammation and pain.  NSAIDS used in veterinary medicine include aspirin, carprofen (Rimadyl), deracoxib (Deramaxx), etodolac (Etogesic), meloxicam (Metacam), and firocoxib.  Your veterinarian will discuss the NSAID options with you and decide which is best for your dog.

Aging dogs often have medical conditions that affect the management of osteoarthritis and the use of these drugs.  Kidney, gastrointestinal, or liver conditions much be assessed to make sure your dog is able to metabolize and excrete the medications.  A complete history, physical exam, and blood work are thus necessary prior to initiating NSAIDS along with periodic follow-up blood work as determined by your veterinarian.

Slow-acting Disease Modifying Osteoarthritis agents

Neutraceuticals are nutritional supplements believed to have a positive influence on cartilage health by alternating cartilage repair and maintenance.

Glucosamine and chondritin sulfate are often used (Glycoflex, Cosequin, Dasequin, and Adequan are a few of these).  They are purported to help improve cartilage metabolism.  They may be more helpful in early osteoarthritis than in chronic, long-term osteoarthritis.  Some people report great success by using them, others do not.

Essential fatty acids (DHA and EPA), the omega 3 and omega 6 fatty acids, have been shown to have marked anti-inflammatory effect when added to the diet at proper levels.  As mentioned above, veterinary joint aid diets contain both of these supplements or they can be added to your pet’s current diet separately.

Acupuncture

Many animals benefit from the ancient Chinese practice of acupuncture.  Acupuncture points (acupoints) are specific spots on the body surface where a practitioner applies stimulation for the diagnosis and treatment of disease.  Thousands of years of clinical practice along with modern research have shown that each acupoint possesses special therapeutic effects.  Each acupoint has a unique location and physiological effect.  Some dogs experience less pain following treatment, allowing a decrease in the use of NSAIDS.  This is particularly helpful in dogs with decreased kidney or liver function.

Environment

There are many things you can do at home to help your dog with osteoarthritis.  Keep your dog in a warm dry environment, away from cold and dampness.  Use a soft, well-padded bed.  Provide good footing to avoid slipping and falling.  Carpet runners work well on hardwood floors.  Minimize stair climbing by using ramps.  You can purchase these from pet stores or make them yourself.  Portable ramps are available to assist dogs getting in and out of cars.  Avoid overdoing activities on weekends and excessive play with other pets.

Together with your dog’s veterinarian you can come up with a plan involving some or all of the above treatments to help with your pet’s osteoarthritis.”

 

If my cat has arthritis what can I do to help?

arthritic catAlthough there aren’t as many NSAIDS available for use in cats, there are some options.  There are neutraceuticals that can be used as well.  Reducing weight in cats is important as the added strain of extra weight especially when jumping is extremely difficult on the joints.  The hips, knees and especially the shoulders and elbows are affected.  Purchasing a shallow litter box can help if your cat has been having difficulty getting in and out of your current litter box.  Helping your cat up and down from surfaces can help reduce the strain from jumping.

In the Eye of the Storm

by: Jennifer Oldfield

6085194497_74a8ffc355_n

So many of us love thunderstorms, we look forward to summer and the opportunity to sit and marvel at mother nature; the flashes of light, the giant booms.   Unfortunately, many pets do not share these feelings and dislike, or even fear, the storms that we love.  As someone who now has two dogs that are not fans of thunderstorms, I have been doing my research on how best to ease my companions’ fears.

Let’s start at the beginning:  my youngest dog Drift’s fears began several years ago when we had a slew of storms back to back over a couple of days, with the heart of the storm being over our home for extended periods of time, and during which the pets were home alone.   Over the course of the years since, I have been working on finding the best ways to help him deal with (and maybe even overcome) his fear.  During this process we discovered with a recent storm (that happened to occur right over our home at 2 in the morning) that likely his stress and aging has lead to our oldest dog becoming fearful of thunderstorms as well. 

It can often be very difficult to help your pet deal with the stress of a storm because they know well before we do that the storm is coming.  They are aware of all the changes to the air and the environment that we don’t see.  So, how does one deal with reducing your pet’s anxiety and, with any luck, resolving the fear?

There are a few things that can be done:

  1. prescription medication
  2. pressure point stress reduction
  3. non prescription alternatives
  4. conditioning

 

1. Prescription Medication

The prescription medication often used is a sedative type drug.  Although certainly helpful, is a bit difficult for several reasons:

a) For best results it should be given an hour prior to the arrival of the storm:  it can be hard to predict when that will be and it is hard to do if you have to work all day and a storm is expected sometime in the afternoon.  Given too soon means it may be worn off by the time the storm arrives.

b) If given when the storm arrives it takes approximately 30 mins to be effective and for some dogs, if they are already very stressed, it may have no affect.

c) There were times when a storm was expected, I gave the medication and no storm arrived.  Although there is no harmful side effect, I felt bad sedating my dog for nothing.

2. Pressure Point Stress Reduction

You may have heard of something called a “Thundershirt”.  This item is designed based on the Tellington TTouch method of stress reduction and relaxation.  The “shirt” fits snugly on the body and applies pressure to specific areas that are involved in the reduction of anxiety. The benefit of the shirt is that it can be worn all the time if needed.  The downside is that if your home is not air-conditioned it could cause your dog to become overly warm as the air can’t circulate against the skin where the shirt is. Also, if you have a dog that isn’t happy about wearing it and is destructive, they may just wreck it or worse yet, eat it.

3. Non Prescription Alternatives

There are various homeopathic options available in pet stores.  Although I can’t speak on this because I don’t know enough about them, that doesn’t mean that they are bad or good.  If you are considering one of those options it is best to discuss it with your trusted veterinarian.  Homeopathic medications can react with other medications or have negative side effects.  Best to be safe and be sure before giving.

Zylkene is a natural product made from the casein found in mother’s milk.  Although the product can be given “as needed“, it does work best if there is some build up in the dog’s system.  It is safe to give on a constant, ongoing basis.  So you could start giving it either at the beginning of summer until the fall when the risk of thunderstorms is over, or if the forecast is calling for a storm in the next couple days you could give it immediately and stop it after the storm.  However, going with the latter method does not aid in the cases where a storm is unexpected.

Adaptil is a natural product based on the pheromones emitted by a mother for her pups at a very early age.  Adaptil comes in 3 methods of delivery: plugin, spray or collar.  For dogs with thunderstorm issues the plugin is best (it lasts 4 weeks before a refill is required).  It is most effective if it is plugged into the wall closest to your dog’s resting place.  The pheromone is only detectable by dogs, so you will not notice any scent in the air.  If you are traveling, you could use the collar (put it on 24 hours prior to leaving so it can take effect) or you can use the spray that can be spritzed onto a dog’s bedding.

 4. Conditioning

Conditioning is a way of training your dog to elicit a different response to a stimuli.  For thunderstorms, it would be teaching them to be calm and relaxed with the thunder instead of stressed and nervous.  Although conditioning is a great method and is definitely something that ultimately will work wherever you go, it is also the most time-consuming.  You must be devoted to working on the behaviour for every single storm.  One storm where you aren’t training and the behaviour can back slide.

 

With knowing the possible options, how do you choose?

Work together with your veterinarian to decide the best choice or combination of choices for both your dog and your lifestyle.  For me personally, here is what I did:

I began with the prescription medication because it was an immediate resolution to a storm that was coming.  I ordered a Thundershirt and while I waited for its arrival I used the prescription medication.  Once it arrived I would put the thundershirt on Drift for stormy days before leaving for work.  If the storm was about to (or I knew was going to) happen in the morning, I also did the prescription medication.  If, when I arrived home, the storm had yet to occur but was still possible I left the thundershirt on and gave the medication.  On days when the storm was occurring in the afternoon before I got home, and the shirt wasn’t quite enough to settle him, I would put him in the crate with my other dog for comfort once I got home.  (Unfortunately this may possibly be part of what has started her recent anxiety).

In the beginning, on days when I was home for the storm, I would put the thundershirt on, give Drift the medication, and cover his crate. ( His crate is his own personal “go to” place sofelt it would be more stressful for him to keep him out with me.).  Eventually when I noticed he was less stressed at the first signs of a storm I would skip the prescription medication.  Whenever there was thunder in the distance and he didn’t whine or cry I would verbally praise him and give him a treat.  Initially, food rewards were not accepted if the thunder was too close.   Over time I have found that the thundershirt alone is sufficient to ease his anxiety and I no longer come home to a worried and panicked pup if there has been a storm during the day.  However, because I don’t intend to leave the thundershirt on always, I am looking at the alternatives for days of unexpected storms.

With Finny’s new reaction to the thunder I am planning to try the Adaptil plugin.  I can place it right where both dogs sleep and since it is always “on”  I don’t have to worry about any unexpected storms during the day or the night.  I will also be ordering a thundershirt for her.  Between the two items I am hopeful that both dogs will no longer worry about storms and am excited about the other potential anxiety issues that may also be resolved with the Adaptil.

I personally have not tried the Zylkene, mostly because I worry that days will go by with it not being given because we have forgotten or one person thought the other was doing it.  I do know people who use it and find it to be extremely helpful.

All the items listed above are also useful for fireworks (dogs afraid of thunder are almost always certain to react to fireworks if they are close) and other stress and anxiety related disorders.  If you have any concerns about your dog’s behaviour contact your trusted veterinarian for advice.

Zylkene is a product we always have in stock, the Adaptil can be ordered (and may become a regular product), and we can also order the thundershirt for you too.  For more information contact us.
