Before offering glucosamine and chondroitin supplement
- Check the exact animal and preparation: the listed suitability is Dogs; Cats; Horses; Rabbits (product-specific). A food being edible does not make it a complete diet.
- Follow the preparation advice: Choose a product with a clear, species-appropriate dosing guide and introduce gradually. Do not substitute a seasoned or processed version and assume the same safety.
- Portion guidance: Follow the product label and discuss the choice and dose with a vet, especially alongside other joint medication. For a pet on a prescribed diet, discuss extras with the vet first.
- If your pet develops vomiting, diarrhoea or discomfort, stop offering the extra and seek advice. Suspected poisoning or breathing difficulty needs immediate veterinary help.
