Can dogs eat liquorice, and why?
Liquorice is best avoided for dogs and should not be given as a treat. Real liquorice contains glycyrrhizin, which in larger amounts can raise blood pressure and lower potassium; the sweets add sugar and some sugar-free versions contain toxic xylitol.
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
Real liquorice contains glycyrrhizin, which in larger amounts can raise blood pressure and lower potassium; the sweets add sugar and some sugar-free versions contain toxic xylitol.
If your dog has eaten liquorice, 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.
