Introduction – Background

This food was created by Michael for his Black Lab Max. Michael started researching dog food and didn’t like what he saw, so he created Nulo. He worked with animal nutritionists, veterinarians, and food formulators to create a diet that he felt good about feeding his own Lab Max. Nulo is high in animal protein and lower in carbs than many kibbles.

While this food may be lower-carb then some, it still has more carbs than protein if you break it all down and do the math. So, if you are looking for a truly low-carb food for your dog this isn’t it.

It is a nice thing that they include Omega-6 and Omega-3 Fatty acids. While these nutrients are not recognized as necessary by the AAFCO I am sure that you have heard of omega fats described as “essential fatty acids.” Omega fatty acids are indeed essential to humans as well as dogs, so their addition in this kibble is quite nice. However, omega fats are very delicate and easily destroyed by heat. Most kibbles are cooked enough to destroy omega fats so are they really in this kibble in a usable state?

Nulo also includes a probiotic in their food that can withstand the heat of processing. This seems like a great thing, but I have questions. It’s one strain of probiotic… if that one strain takes over in your dog’s gut is that a good thing? Your dog’s gut should be like a rainforest with many, many different species of probiotics, not just one. I can’t help but think that over time this could cause problems.

Nulo may be a good option for your dog. It is lower carb which is good, though it is by no means “low-carb.” The kibble also has added probiotic and omega fatty acids which may be helpful or may not. Omega fatty acids are fragile and may be cooked out of the kibble completely. Also, a single probiotic strain may not be that helpful. Overall the ingredient list looks pretty clean, though there is no mention of ingredient quality.
