as of 5 October 2021 23:21

Sometimes, dogs can be picky and dry food just will not cut it for them. If your dog is like this, just add Nulo Adult & Puppy Grain-Free Canned Wet to their food and they will chow down in no time.

Key Features

  • Protein Content—10%
  • Fat Content—7%
  • Carbohydrates—1%
  • Antioxidants—5%

Dogs love meat, so they deserve a wet food that satisfies their meaty craving while giving them the nutritional intake that their bodies need.

The majority of the ingredients used, over 80%, are animal proteins that provide the ideal level of protein, fat, and amino acids that their bodies need to stay healthy and grow strong.

There is also a hardy addition of vegetables for essential vitamins and minerals. Since wet food is mainly animal protein based it does have added vitamins and minerals the food alone cannot provide as well as supplements, which helps make wet food a healthy food source and not just a meat source.

It is best to mix the wet food with dry to entice your dog to eat rather than just feed your dog wet food since this can cause unnecessary water weight gain in your dog.


  • Grain and corn free
  • Free of preservatives, artificial colors, and artificial flavors
  • Ideal for all life stages
  • Comes in 13OZ cans individual or in cases of twelve


  • Some customers have claimed the wet food had too much fat on the edges

Nulo Adult & Puppy Grain-Free Canned Wet food will add a pleasing taste to your dog’s dry food while giving them an extra nutritional boost.

Bottom Line

Although Nulo pet foods do not list where they source their ingredients from on their website the fact that they have not had any recalls since they opened shows promise.

Their ingredients are being taken care of and sourced properly so that they pass dog food safety standards and have not caused any major issues in pets who have consumed the products.

Although we have not tried it, you can always try and contact the company directly to see if they can answer where they source their ingredients before you try your dog on one of their formulas.

Or if you trust them we are sure you will start to see how much better your dog’s body will become as they eat Nulo.
