🩺 Talk to your vet. Preventives and supplements depend on your pet's species, weight, age, health and local risks. Read every label; never use a dog product on a cat.
Evidence for glucosamine and chondroitin is mixed; some dogs seem to benefit, others don't. Weight management, exercise and vet-prescribed treatments matter more. Ask your vet.
Not always. Always tell your vet what you're giving, especially before surgery or if your dog is on prescription drugs.
