Yes, you can feed your dog fish roe. Fish roe is a nutrient-rich food filled with Omega 3 fatty acids and other essential vitamins and minerals. It is a great source of protein for dogs that can be beneficial for their overall health. However, it should always be given in moderation as too much could cause gastrointestinal upset or allergies in some dogs. Additionally, when feeding your dog fish roe make sure to cook it thoroughly and remove any bones before serving as they may cause an obstruction if ingested by your pup.
