Apple cider vinegar is great for dogs with gut issues. It helps to rebalance the PH in their gut and improve their digestive system. You only need to add a small amount to your dog's food. Start with 1/4 teaspoon to 1 teaspoon per day for small dogs (up to 10kg/22lbs) and 1 to 2 teaspoons per day for medium to large dogs (up to 45kg/99lbs). #dogsofinstagram #doglover #guthealth #dognutrition #dogfood #applecidervinegar | The Dog Nutritionist
