FreshpetGrain Free Chicken & Spinach Dog Food

The most common protein in pet food, and for dogs one of the most common food allergens, with beef and dairy. If chicken is what your pet reacts to, it hides everywhere: chicken fat, chicken broth, chicken meal, natural flavor. On a label, chicken listed first is weighed with its water still in, so a food leading with fresh chicken often has less chicken protein than one leading with chicken meal. Neither is better; they are different measures.

The liver of the chicken, used both as a nutrient-dense ingredient and as a flavor. It is rich in vitamin A, iron, copper and B vitamins and most pets find it very palatable, which is why it turns up in treats and as a coating on kibble. Because it is chicken, it counts as chicken for a pet with a chicken allergy, even when it appears far down the list.

The familiar white potato, used as a carbohydrate source in many grain-free foods. Potato starch binds kibble; potato protein is a concentrated plant protein that lifts the protein figure on the bag. Cooked potato is safe and well digested. Grain-free foods built on potatoes and legumes were part of the FDA's 2018 to 2022 look at diet-associated heart disease in dogs, which did not establish a cause; the agency has not asked for any to be withdrawn.

A complete, highly digestible protein, which is why formulators like it. It is also a documented allergen in about 4% of dogs with food reactions. Egg allergy does not implicate chicken meat; the proteins are different. Dried egg product is the same thing with the water removed. A good ingredient for most pets and a fine-print one for the allergic few.

A leafy green added in small amounts for vitamins, minerals and color. Spinach is high in oxalate, which binds calcium and in large quantities is a concern for pets prone to calcium oxalate bladder stones. The amounts in a complete food are tiny, often a fraction of a percent, so for most pets it is a token vegetable with no nutritional or safety weight.

A vegetable added in small amounts for fiber and a little flavor, and in fresh or raw recipes for its water content. It is safe for dogs and cats and appears well down the list, often alongside other vegetables in a blend. It brings almost no calories and only trace nutrients at these levels, so it changes nothing about the food either way.
