Is it Safe to Use Glucosamine Sulfate on Dogs?

Glucosamine is a popular nutraceutical supplement for pets suffering from osteoarthritis, hip dysplasia and other painful conditions that deteriorate joint tissue. The two most popular forms of glucosamine are glucosamine sulfate and glucosamine hydrochloride; both are equally safe and effective for dogs.

Glucosamine Defined

Glucosamine provides the compounds necessary for a dog's body to rebuild new cartilage. It is made from hydrolyzed chitan, a fibrous sugar found in crustacean shells.

Types

Glucosamine hydrochloride is pure glucosamine, whereas the sulfate form is slightly less processed. Human clinical trials have found glucosamine sulfate and glucosamine hydrochloride to be equally safe and effective.

Human-Grade vs. Veterinary

Veterinary forms of glucosamine sulfate are often flavored to appeal to dogs, and they may contain vitamin C, which enhances the product's absorption. However, some pet-owners give their dogs human-grade products because they are often of higher quality.

Side Effects

Side effects from glucosamine sulfate are uncommon in dogs. Some dogs will experience vomiting or diarrhea after taking glucosamine, but this may improve after a few days of supplementation.

Minimizing Risk

To prevent potential dangers, pet owners should take care to give only the recommended dose of glucosamine. Drug interactions from glucosamine are rare but theoretically possible. Tell your veterinarian about any supplements that your dog is taking.
