When choosing dog food for your senior pet, you should always aim for premium sources of protein. Lamb is an excellent choice, and you will find it in many top of the line dog foods, due to the high content of amino acids, as well as its ability to maintain your dog’s bones and muscles in excellent condition.
You should also bear in mind that your dog should like the food you buy for him. If your pet is a picky eater, you will be pleased to learn that most dogs love lamb in their food, which means that yours might like it, too.
