Whatâs a grain free diet?
A puppy on a zero grain/grain free/no grain diet doesnât eat any grains at all. So no wheat, no soy, corn, barley, rye, or rice, among other things. Different puppy food manufacturers often have different stances on whether your best friendâs dinner should contain grains or not. Some argue that grains, like rice, are a natural source of carbohydrates that puppies need for energy. Others believe that puppies do best when fed on high-protein, meat-based formulas that cut out the inessential carbohydrates. But whether you come down on one side of the fence or the other, itâs always worth knowing whatâs on the market.
Itâs important to understand that a grain-free diet is not the same as a gluten-free diet because some grains do not contain glutenâ oatmeal is a good example of a gluten-free grain. Puppies who are allergic to gluten should probably be fine with some grains, while those who canât tolerate grains need to be entirely grain-free.
It is worth noting that a lot of owners choose grain free puppy food over regular puppy food because grains like corn and wheat are commonly used as âfillersâ. Because these grains are often cheaper than real, high-caliber meat, theyâre often found in poorer-quality puppy foods as a way to bulk it up and produce it economically.
Why do puppies need grain free puppy food?
First and foremost, puppies who are allergic to grains need to be kept on a strictly grain free puppy food diet. Itâs also advisable for those puppies who have intolerances (which are different from allergies) to stick to grain free puppy food. Just like you and I wouldnât eat something that makes us feel itchy or sick, our puppies deserve a yummy dinner without any discomfort!
Beyond allergies and intolerances, thereâs no strict scientific reason why your puppy should be on a grain free diet. The most important thing to remember is that your pup needs a balanced and healthy diet that provides him with sufficient high-quality protein and fat for growth. When youâre looking for the best grain free puppy food, therefore, youâll want to check out things like whether it:
- Contains artificial/synthetic preserving agents, colors, or flavors;
- Meets AAFCO standards for nutrition;
- Features real meat or ambiguous by-products (like milled poultry by-products) as the main ingredients;
- Includes natural and vitamin-rich vegetables and fruits; and
- Has nutrients and oils like DHA, chondroitin, and glucosamine for healthy puppy growth.
How do I feed my puppy a grain free diet?
Besides âGrain Freeâ, the most common thing youâll see on grain free puppy food packets is usually going to be: âNo wheat, corn, or soyâ. Depending on why youâre feeding your puppy a grain free or gluten free diet, this may or may not be enough. Some further tips for feeding your puppy a grain free diet include:
- Looking at the ingredients list, and doing a check that there arenât things like rice, barley, or rye;
- Choosing a reliable puppy food brand that is transparent about its quality and safety standards;
- Looking for a specific âGrain Freeâ or âGluten Freeâ promise on the puppy food bag; and
- Avoiding table scraps â no matter how cute their puppy dog eyes!

FAQ
Is a grain free diet safe for my dog?
This is a loaded question in the veterinary community. While some vets promote the benefit of offering a grain free diet to sensitive dogs, there are recent studies that have found evidence of long term grain free diets leading to serious heart conditions. The best advice we can offer is to speak with your vet before switching your dog to a grain free diet.
Your vet can discuss whether your dogâs symptoms are severe enough to warrant the switch, and how they personally feel about the possible risks. Some dogs will be perfectly fine living their lives on a grain free diet, but itâs best to speak with a professional to be safe!
How do I know if my dog is allergic to grains?
If youâre worried that your puppy might be suffering from any form of food allergy, the best (and first!) thing to do is take him straight to his vet. Your vet will be able to carry out the necessary tests that can help identify what exactly it is heâs allergic to. Common symptoms of food allergies, including grain allergies, can include vomiting, bad gas, diarrhea, and tummy upsets. In extreme cases, unfortunately, puppies can react to food that theyâre allergic to by going into anaphylactic shock, just like humans.
Puppies and dogs who have a suspected food allergy will generally be put on a food elimination diet by their vet. This can take up to three months, during which your fluffy friend will trial-and-error different foods that leave out the suspected ingredients.
My puppy is not allergic to grains, but he reacts badly. Why?
Best practice says you should take your puppy to the vet, as it is possible that he may have an intolerance to grains or gluten. Puppy food sensitivities, also called intolerances, are not as serious as allergies. They can, however, be deeply uncomfortable for your puppy. Pups with grain insensitivities may demonstrate gastrointestinal distress â like with allergies, this can manifest as diarrhea the day after they eat something with grains. Foot, ear, or skin infections can also be a result, as well as itchiness.
If your puppy doesnât take well to his food, itâs highly recommended you visit his vet. Thereâs always a chance that itâs not grains or gluten causing the problem, but another ingredient. Your vet should be able to help or refer your puppy to a specialist who can.
