5 Best Limited Ingredient Dog Foods in [2021]

Canines are descendants of the noble wolf, but, did you know that evolved alongside humans – developing some of our not so nice traits such as food sensitivities too.

Their digestive system has changed dramatically over the years – no longer suited to only eating raw meat, the domesticated dog’s digestive system is now able to break down cooked foods, as well as starches, and carbohydrates.

While many dogs seem to be able to eat anything, there are some that have intolerances and allergies to certain ingredients such as grain, or beef. For that reason, we’re going to take a look at some of the best-limited ingredient dog food to help all of you sensitive pooch owners find a diet to suit your four-legged friend’s needs!
