Generally, supplements are a safe way to treat dog arthritis. However, there are cases where supplements have caused diarrhea, vomiting, or a itching in dog’s skin. These are common indications that your supplement may be causing an allergic reaction.
Allergies occur when your dog is exposed to an allergen (antigen) frequently. Below is a list of common allergens that could be found in your dog arthritis supplement:
- Animal protein from beef, chicken, or pork, especially cow or pig liver or
- Other natural flavorings
- Shellfish
An allergic reactions only develop when your dog has been exposed to something before. This means a dog cannot be allergic to something it has never had before. This simple piece of information can help dog owners apply a method to screen which supplements are safe for their pet.
With a trial and error approach, dog owners can identify the cause of the allergic reaction. Below is a simple guide:
* Make sure to feed your dog one type of food that will not cause an allergic reaction.
* For 4 weeks, use Adequan or Cartrophen. These drugs are normally safe for allergic dogs. You can read previous posts on these drugs.
* You can then give an oral dog arthritis supplement. I suggest you follow the order I have made for supplements to test.
1. Dasuquin. It is only logical to test the best supplement first. Nonetheless, Dasuquin may get a reaction from allergic dogs since it contains beef and shellfish.
2. Synovi G3 low allergen granules. This is made from a “novel marine protein”. These are hard to find.
3. Deva Vegan Glucosamine with MSM and CMO. It is made from vegetables so it is less likely to cause an allergic reaction than animal protein sources.
4. Omega-3 Supplements. The best kinds are the ones made from fish oil such as Welactin, but if your dog is allergic to fish he may react to these. Omega 3 supplements can also be taken from flax seed - a good source vegetable Omega 3. Read my previous post on Flax seed before using this!
* Administer the chosen dog arthritis supplements for 2 weeks. Do not change anything in your dog’s diet. If your dog starts to scratch or develops stomach problems then your dog may have an allergy to the supplement. Stop using the supplement. Wait for your dog to recover. The restart the process with a different supplement.
When I first tried this on my pet, it took a while before I was able to discover the safest dog arthritis supplement. As a vet, I share with my clients the importance of patience in this process. Although it may be hard at first, your dog’s health and happiness, when you find a dog arthritis supplement that is safe to administer, is truly priceless.
