Can dogs eat acorns, and why?
Acorns are poisonous to dogs and must never be eaten. Tannins and gallotannins can cause vomiting, diarrhoea and kidney or liver damage, and whole acorns can cause blockages.
Dogs are omnivores, so most of their diet should be a complete, balanced dog food, with treats on top. They cope with a wide range of foods, but rich, fatty or sugary ones can cause stomach upset and, over time, weight gain or pancreatitis.
Warning — what to watch for
Tannins and gallotannins can cause vomiting, diarrhoea and kidney or liver damage, and whole acorns can cause blockages.
