Do Canine Joint Supplements Contain Potentially Harmful Ingredients?

Canine joint supplements are commonly used to assist aging dogs or dogs with joint injuries. A dog may receive both relief from pain and improved mobility as he continues to take these supplements, but caution must be used when selecting a joint supplement as some ingredients used can be potentially harmful.

Ingredients That May Be Harmful

  • NSAIDs (Non-Steroidal Snti-Inflammatory Drugs) have been linked to both kidney and liver damage when used for prolonged periods of time. NSAIDs can also cause joint deterioration.
  • Steroids can have beneficial effects but are typically started at a particular dosage, tapered off and then discontinued. Prolonged use is not recommended as steroids can also cause joint deterioration.
  • Menadione (may be listed as Vitamin K3 or Vitamin K) is a fat soluble vitamin and is easily stored in the fat cells of the body, building to a toxic level.
  • Active yeast cultures can expand and cause stomach problems in dogs.
  • Even natural or herbal remedies have been known to have negative health impacts on dogs. Yucca has steroids in it that impair the repair of joint tissue. Bromelain, found in pineapple, eats away the interior lining of the GI tract and can produce allergic reactions in dogs. Whether a chemical or natural/herbal joint supplement, it is best to do your homework on the ingredients to avoid any negative impact on your dog.
