Some of these are discussed and reviewed for your convenience:

1. Chicken, Rice & Vegetable Formula; Puppy

This is an excellent choice for most active puppies as it consists of probiotics to help indigestion. However, it is low in fiber.

2. Chicken, Rice & Vegetable Formula; Adult dog

A good choice for active adult dogs. Has probiotics for good digestive support. Yields very good joint support. On the other hand, avoid feeding these to overweight dogs due to their high-fat content.

As we were just talking about overweight dogs, here is the perfect diet food for them with low-fat. A better choice for dogs with digestion problems because it is extremely fibrous and has probiotics. Provides great joint support.

However, due to being a low-fat diet, it has only one meat source and hence should not be fed to all types of dogs.
