Dogs may develop allergies to any number of common pet food ingredients, include grains like corn and wheat. Some owners turn to grain-free dog food to help dogs struggling with food allergies or other health issues. There are both wet and dry options that come in a variety of flavors, so you're sure to find something your dog will like.

Of course, it is important to check with your veterinarian before making any diet changes. Although some claim that grain-free diets offer many health benefits to pets, there isn't a lot of scientific research to back these claims. In some cases, a grain-free diet may in fact not be appropriate for your specific pet, particularly as the FDA continues to investigate a possible connection between grain-free diets and a heart condition called canine dilated cardiomyopathy.

“Grain-free dog food is only necessary if your pet has been diagnosed with an allergy or intolerance to grains via an elimination diet trial. This type of allergy is rare in dogs,” says veterinarian Kristin Wuellner, an employee of Hill’s Pet Nutrition.

If you and your vet determine that grains are a problem, here are the best grain-free dog foods on the market you.

Made with real roasted meat and vegetables like sweet potatoes and peas, it’s packed with nutrients and highly digestible.

The food features recipes for both puppies and adults and can be purchased in up to 30-pound bags (the smallest is five pounds). Dogs may think it’s a treat rather than dinner.

Best for Seniors: Halo Purely For Pets Holistic Grain-Free Natural Dry Dog Food for Senior Dogs

Senior dogs have different needs from younger ones. "The biology of mature dogs changes around seven years of age and certain nutrients are needed to support healthy functioning of organs, bones and muscles,” says Dr. Wuellner. “As dogs enter their golden years, their metabolism often slows down significantly, so they typically eat fewer calories than when they were younger, yet still need the full complement of essential nutrients.”

Halo’s grain-free offering is made with lower calories and fat than other varieties to make up for the reduced activity and lower metabolism that’s normal in older dogs. It also features real meat, poultry and fish, and non-GMO fruits and vegetables.

One key factor that some owner prefer is that the proteins are “whole,” rather than the meat meals used in some brands. It’s sold in either four or 10-pound bags. It can help older dogs maintain a healthy weight and is free of some of the undesired ingredients present in some brands of dog food.

What to Look for in Grain-Free Dog Food

Age and Breed Size

Always check the age and size requirements of the dog food. Nutritional requirements are different for older and younger dogs, as well as smaller and larger dogs so it's important to find a grain-free dog food that will meet those needs.

Ingredients

It's always important to check the ingredients in your grain-free dog food. You will want it to be free of artificial flavors, preservatives, and poultry-by products to ensure that your dog is getting a healthy meal. Also, take note of the carbohydrates in the food you're buying. Since grain-free food often substitutes grains with potatoes or sweet potatoes, their carbs can sometimes be higher than grain food. This is important to look for if you're watching your dog's weight.

Caloric Needs

Whether your dog is a picky eater or needs to be on a diet for weight loss, make sure that the food you choose meets their caloric needs. It's always a good idea to consult with your veterinarian to determine the right number of daily calories for your dog. There are plenty of options on the market that are specially formulated to help you achieve your pet's health goals.

“The caloric requirements of puppies are much higher than adult dogs, and if not fed a diet that’s calorie dense enough, they may lack the energy necessary for growth and development,” says Dr. Erin Katribe, DVM, MS, medical director and veterinarian for Best Friends Animal Society. “In contrast, older dogs tend to have slower metabolisms, and senior diets have nutrient profiles that are adjusted to prevent or slow the onset of chronic diseases that we commonly see in older pets."
