It should not displace treatments with stronger evidence. Few supplements have become as closely associated with canine arthritis as glucosamine. It appears in tablets, chews, powders, prescription diets, and combination products. Owners often begin it at the

Pet owners worry about causing cancer by vaccinating their cats. Veterinarians worry about balancing disease prevention with a rare but devastating complication. A new systematic review and meta-analysis published in the Journal of Small Animal Practice provides one of the most comprehensive evaluations

The idea seemed straightforward: inject stem cells into damaged tissue, allow them to become new cartilage, tendon, or other specialized cells, and watch healing occur. But science has a way of challenging our assumptions. Today, many researchers believe that stem cells may not be the primary treatment at all. Instead, much of the
