Avocado is not safe for Border Collies and should never be offered. Avocado contains persin which is toxic to dogs for Border Collies. There is no safe serving size — even tiny amounts can cause serious harm.
Persin causes vomiting diarrhea and heart damage. If your Border Collie has accidentally eaten Avocado, do not wait for symptoms. Contact your vet or ASPCA Poison Control (888-426-4435) immediately — early treatment dramatically improves outcomes.
