How Diet Can Help

1. Omega-3 Fatty Acids (EPA, DHA) Anti-inflammatory. Best source: fish oil. General supplementation: about 20–55 mg EPA+DHA / kg body weight / day; for arthritis your veterinarian may set about 50–100 mg / kg. NRC (2006) safe upper limit: about 370 mg EPA+DHA / kg body weight^0.75 / day. On anticoagulants or NSAID pain relievers, give fish oil only after consulting your veterinarian.

2. Glucosamine, Chondroitin Support cartilage health.

3. Weight Management Every extra kilogram adds additional strain.

What to Avoid

  • Foods high in omega-6
  • Rapid weight gain in large breed puppies
