Sadly, some puppies may be born with liver shunts - these are abnormal branches of blood vessels in and around the liver.
Often these can be corrected by specialist surgery but where surgery is not possible, a low-protein diet will be recommended for your dog. Reducing the amount of protein in the diet can help to decrease the amount of toxic substances that may be absorbed from the gut.
If your dog has a persistent liver shunt or a shunt that has been operated on successfully, we recommend you speak to your vet about the suitability of feeding Butternut.
