Yes. Chicken on its own is not a balanced diet. But as part of a diet that includes other vitamins and minerals then chicken is a good source of lean protein.
For dogs that are prone to getting an upset tummy it is a good idea to keep their diet as consistent as possible. Changing the source of protein in the diet suddenly can lead to excess gas or diarrhoea.
Therefore feeding your dog chicken everyday, as part of a balanced diet, is a good choice, especially for dogs who have sensitive tummy’s.
