Can dogs eat oat milk, and why?
A little plain unsweetened oat milk is not toxic but is unnecessary and best avoided for dogs. Sweetened versions are sugary and some contain xylitol; offers no real benefit.
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
Sweetened versions are sugary and some contain xylitol; offers no real benefit.
If your dog has eaten oat milk, don’t wait for symptoms — contact your vet immediately, or call the Animal PoisonLine on 01202 509000 (24/7, UK). Signs of a problem can include vomiting, diarrhoea, drooling, lethargy, tremors or loss of appetite.
