Best dog foods for allergies 2024 according to pet owners and experts

Even when you’re looking specifically for the best dog foods for allergies, there are still an overwhelming number of options out there. It’s tough to figure out which food is right for your loyal pup. But don’t fret, because we’ve put together this comprehensive guide by talking to experts and real pet owners.

Figuring out that your pet has allergies in the first place can be tough, but the most common symptoms to look out for are vomiting, diarrhea, and itchy skin. These can be caused by a food allergy — a 2019 study in the Canadian Veterinary Journal found that "6% of all skin diseases in dogs and 20% of all allergic dermatological signs in dogs have been attributed to adverse food reactions". Some of these symptoms can be treated, as some of the best dog conditioners are designed to aid with itchy skin, but it’s always best to treat the cause as well as the symptom

It’s also worth noting that there could be other causes for these symptoms including environmental allergies and fleas..As such, it’s important to get a diagnosis from your vet before you make any changes to your dog’s diet and healthcare. We have a full guide to food allergies in dogs that you can check out for more information, including tips on symptoms, diagnosis, and treatment. And if it does turn out to be fleas, our best flea treatment for dogs guide has you covered

If you have confirmed which allergens your dog needs to avoid, our guide to the best dog foods for allergies is here to help you choose the right food for their needs. We’ve tested all of the foods we recommend below, and consulted with our expert veterinarian Dr Joanna Woodnutt to make sure our guide is second to none.

The best dog foods for allergies we recommend in 2024

Best overall

Our tester Sarah reported back that her dog loved the Merrick Limited Ingredient Dry Dog Food. Despite not being the biggest fan of salmon products usually, this one went down a treat and Duke the dog “absolutely loved it”. He has slight digestive issues, and Sarah notes that this food helped his tummy while maintaining his weight. 

Duke normally likes his kibble with some broth or water mixed in, but as Sarah poured the food into his bowl, he had already stuck his head in and started tucking in. Sounds like a winner to us!

She says: “He finished it right away. A week later, he is still eating it with great fervor (he usually gets sick of the same food over and over, but hasn’t gotten sick of this yet which is amazing!)”

Sarah says this food is well worth the cost. However, the packaging is a bit tricky to store due to it being so big and bulky, and the bag is not resealable.

Sarah says: “This makes it really difficult during feeding time, but not enough to be a hindrance to the quality of this product. It does have a slight fishy smell, which is also why a Ziploc seal or some type of seal would be best for this type of dog food. I found myself having to make extra effort sealing it each time and is something I have to do to avoid the fish smell from leaking out.”

Dr Joanna Woodnutt says: "This range contains limited protein sources, reducing the chance of a food allergy. The inclusion of fish oils and flaxseed adds omega 3 and 6, which have anti-inflammatory properties in the skin.”

Best limited ingredient

On the hunt for a limited ingredient dog food? This could be the one for your pooch. Our tester Michael tried the turkey and potato flavor out and says his dogs, Tito and Petey, loved it. The pair rarely eat dried food in one sitting, but they chow this one down every time it’s placed in front of them.

For those worried about the bad smells that canned foods often have, you’ll be pleased to hear that this doesn’t have one, according to Michael.  

Tito and Petey previously suffered from itchy skin, but Michael reports that this hasn’t occurred since giving them the food. While the dogs are big fans of the flavor, our tester says it’s a little expensive at over $4 per can. However, they'll go through two cans between them over the course of three days. While the cans are easy to store, they're not resealable, so you might need to buy a lid cover or a storage tin. 

Dr Joanna Woodnutt says: “These limited ingredient diets only contain one protein source, meaning they’re more suitable for dogs with food allergies. The ground flaxseed is a source of anti-inflammatory Omega-3 fatty acids.”

Best premium food

Containing coconut oil for digestive issues and an omega-3 fatty acid for skin health, this dog food promises to “support digestive health and nourish skin”. But does it really live up to this? Pet parent Barbara put it to the test on her dog.

The price point may be slightly higher than the others in this guide, but Barbara says it’s definitely worth the money for the quality. To her, the cost "makes sense". Her dog loves it and immediately started eating it when she first introduced it to his diet.

It comes in a compact bag, with no extra unnecessary packaging, which means you don’t have to worry when it comes to storage. Plus, the bag is resealable meaning no unpleasant smells are going to escape into your home. 

Whilst it’s not the easiest to portion and doesn’t come with a scoop, the bag does have a chart to help you with this. 

Overall, Barbara says: “This is definitely suitable for dogs with sensitive stomachs.”

Dr Joanna Woodnutt says: “This diet contains menhaden oil, a source of essential fatty acids known to have anti-inflammatory effects on the skin.”

Best vet prescribed food

This vet-prescribed food might be a little harder to get your hands on, but promises to help settle digestive issues. Our tester Sarah says it’s a great product that really helps her dog Duke with his digestion problems. However, since you need to get a prescription each time you buy it, it’s on the pricier side since there’s the added cost of booking a vet appointment. 

You’ll be pleased to hear that the food doesn’t have an unpleasant odor, which is a good thing since the packaging is not resealable.

Sarah says: “My dog loves this brand and it really helps his system get back to normal when experiencing digestive issues (diarrhea, vomiting, etc.)”

So how does it compare to the Merrick Limited Ingredient Real Salmon & Sweet Potato Dry Dog Food that Duke also tried?

Sarah says: “Both of them seem to have limited ingredients which is a plus for me when trying to feed my dog. I'm not looking to feed Duke a ton of fillers and preservatives. He does seem to love the Merrick kibble more than his other dry food so that may be a testament to how fresh the kibble is!”

Best on a budget

Our tester Barbara also tried out the Purina Pro Plan Adult Sensitive Skin & Stomach Salmon and Rice Formula Dry Dog Food. 

Containing salmon as the number one ingredient, plus sunflower oil, the brand states that this food is rich in omega fatty acids. This contributes towards to good joint health and promotes a healthy coat, whilst the oatmeal is “gentle on the digestive system”.

Barbara says the quality and quantity of the food are worth the price tag and that her dog loves the taste. “She has always been excited to eat it”, she says.

The downsides are that the packaging is not resealable, which makes it a little harder to store, and it’s not the easiest to portion as it doesn’t come with a scoop. However, there is a chart on the back to help you if you’re not sure about portion sizes. Unlike the Annamaet food that Barbara also tested, she says that this one has quite a bit of extra packaging, meaning it might not be the most eco-friendly.

So how do the two compare? 

Barbara says: “[In terms of] quality, I think they are very similar. The Annamaet food has a stronger smell but since the bag reseals, it doesn’t linger. I would say you get more for your money quantity-wise with the Purina Pro bag. I think both are excellent choices for your pup. It just comes down to which one your dog will enjoy more!”

Best gluten and grain-free option

Looking for a grain and gluten-free option? Vital Essential Freeze-Dried Raw Chicken Entree Mini Nibs Dog Food could work for your furry friend.

Pet parent Nina put it to the test on her dogs, Milly and Sasha, who seemed to enjoy their food. Not only did it get her dogs’ stamp of approval, but the bag was easy to store, shelf-stable, and resealable. Bonus: all ingredients are sourced from the US - something that’s important to Nina when it comes to buying dog food. 

In terms of value for money, Nina says it’s a little expensive when opting for the smaller bag ($35.99 for 14-oz), so she would probably choose the larger option instead ($59.99 for 25-oz).

Best free-range food

Our tester Tiff tried this one out on her 14-year-old Morkie and four-month-old Lagotto Romagnolo. It was clear to see that her two pooches enjoyed the taste as they "absolutely inhaled" it. It came as a shock to Tiff as one of her dogs usually leaves their food for hours before finishing it - but it wasn't the case with this one.

Since Tiff has a puppy (eating more than he would in adult stages), it's hard for her to tell if it's worth the money based on quantity as he goes through food so quickly. However, she confirms that the quality of it is "great". 

In comparison to her regular food, Tiff says: "Our dogs normally eat the Just Food For Dogs Chicken and Rice pantry recipes, which is as outstanding as it is expensive, so I’d say if we’re willing to splurge on that brand, I’d be willing to splurge on Ziwi."

The food is available in 13.75-oz cans as well as a smaller size of 6-oz. Tiff tried out the latter and says it is "exceptionally easy to store". She also notes that there were no smells and she could even put the leftovers in her fridge. 

Tiff reports back that there wasn't a measurement scoop provided, so she had to use wooden chopsticks to get the food out (to avoid metal on metal). 

Tiff says whilst the Ziwi Peak Chicken Recipe Canned Dog Food is great, she prefers the Just Food For Dogs option. 

She says: "We noticed both dogs’ bowel movements were slightly affected by the changed food. Our Morkie had to stop Ziwi as it disrupted her bowel movements and they were softer and greener than normal—she is 14 years old and has been fed Just Food For Dogs her entire life, so we felt it was better not to continue the change.

"Our Lagotto absolutely loved the food and he had regular bowel movements but we did notice they were a bit softer and stinkier than normal. This is likely just a personal preference since we’ve had long and positive experiences with a different brand, which multiple vets have recommended to us for our Morkie, who has had some health issues and signs of inflammation in the past—but if I ever needed a backup brand, I’m extremely happy with the Ziwi Peak Chicken recipe! "

How to choose the best dog food for allergies

If your dog seems more interested in pawing at his ears or scratching her skin than hanging out with you and you’ve ruled out other causes, then it could be time to consider experimenting with their diet. 

But with as many free-from foods on the market for dogs as there is for people, knowing where to start can be daunting. Thankfully, we’ve come up with a few simple guidelines that will help point you in the right direction.

Look for products that have short ingredient lists, generally with one form of protein and one form of carbohydrate which makes it easier to identify the potential allergen. While there are both risks and benefits, raw dog food is another option worth looking into. With few ingredients and zero additives, our guide to the best raw dog food is a great resource if you’re not sure where to start. 

According to Dr. Joanna Woodnutt, “A good diet for allergies has a single protein source, such as lamb, and a single carbohydrate source. This reduces the chance of an allergen being present. If you don’t know what your dog is allergic to, the diet should contain a novel protein - one your dog hasn’t encountered before. Unusual proteins like ostrich and bison are sometimes used for allergy diets for this reason.” 

Novel proteins and other ingredients can work well for a lot of dogs as they won’t have been over-exposed to them in the past. Think venison, rabbit, kangaroo, pheasant and bison, and gluten-free ancient grains and seeds like quinoa, millet, and chia.

Antioxidants from fruits and vegetables and Omega-3 fatty acids are great additions to your pup's diet and are well worth keeping an eye out for. "Dog foods high in omega 3s will also help the skin by reducing inflammation and building a healthier skin barrier," says Dr. Joanna Woodnutt. You'll also want to look for added vitamins, minerals, prebiotics and probiotics. Vitamins C and E and probiotic strains like lactobacillus and acidophilus are particularly great for soothing the GI tract and ensuring good digestive health.

Woodnutt also recommends considering opting for a hydrolyzed diet. "The proteins are too small to cause an immune reaction," she explains. "They are great to use when the dog’s dietary history is unknown. They are also produced in a clean factory, to reduce the risk of cross contamination, as studies have shown the ingredients list on the back of the pack isn’t always accurate when it comes to what proteins could be inside."

Finally, if you’re noticing your dog displaying any of the symptoms of a possible allergic reaction be sure to consult your vet who will be able to help identify the cause and recommend the best course of treatment.

How we tested the best dog foods for allergies

We searched high and low to bring you the very best dog food for allergies. After hand-selecting our favorites, we passed them over to our team of experts who are all dog parents. Their pups got down to business and tested each and every one of the foods listed in this buying guide (it's hard work but someone's got to do it!) Here are some of the things we considered when ranking these products:

• Taste: Our fur babies deserve to be fed like royalty. Taste is a huge factor when it comes to buying dog food so we made sure our testers actually wanted to eat the food. 
• Benefits: If you're switching over your dog food, you want it to be worth it. That's why we scoured the ingredients to ensure they have health benefits for your pup. We then asked a vet to assess the quality of the ingredients. 
• Value for money: No matter what your budget is, we want to make sure you find high-quality dog food that's right for your pet. We tried to include a range of price points so it's accessible for everyone. 

What foods should dogs with allergies avoid?

According to VCA Animal Hospitals, the most common food allergens in dogs are proteins, particularly those found in beef, chicken, chicken eggs, dairy, soy, and wheat gluten. 

However, they note that almost any food ingredient has the potential to trigger an allergic reaction and while protein is the most common cause, other substances, such as artificial colors and preservatives, can also be responsible.

While it’s tempting to just start removing certain foods from your dog’s diet, it’s important that you seek the specialized advice and guidance of your vet to avoid accidentally omitting vital vitamins and minerals that your pup needs to thrive. 

Your vet will be able to run tests that accurately determine exactly which ingredients are causing issues for your dog and work with you to formulate an appropriate diet for them. 

What is the most common dog allergy?

As we’ve seen, food allergies in dogs are not as common as we might think, with the AVMA estimating that only 0.2% of pups will suffer from an allergic reaction that’s been triggered by something they’ve consumed.

So, if food allergies aren’t all that prevalent, what is the most common dog allergy? Well, according to a 2018 State of Pet Health Report from Banfield Pet Hospital, found that flea allergies in dogs have increased by 12.5% over the past 10 years, with environmental allergies up 30.7%.

As always, if you suspect your canine companion is suffering from an allergy, be sure to consult your vet who will be able to let you know exactly what you’re dealing with and outline an appropriate course of treatment. 

Is dry or wet food better for dogs with allergies?

There is no difference between wet and dry food when it comes to allergies, says Veterinary Surgeon Dr Hannah Godfrey. “What’s important is avoiding the allergen (or allergens) that’s causing their reaction. Whether the dog food is wet or dry is unimportant, as long as it doesn’t contain the ingredient that they’re allergic to.”

You may have seen your dog show symptoms after eating wet food, only for them to fade away when you switched to dry, or vice versa, but this is just down to which allergens each food contains, not the type of food.

You can get allergy tests done to determine what ingredients your pet is allergic to, but as Dr Godfrey explains, “allergy tests aren't perfectly reliable, and they can be costly. Therefore, you may choose to skip this step and choose an allergen-free prescription diet to use as your dog's only food intake to see if their symptoms improve.”

Dr Godfrey goes on to explain that the majority of these diets use “hydrolyzation to ensure that the ingredients can't be recognized as allergens by your dog's immune system.”. Most of them are dry food based, which could be where this myth about dry food being better for allergies comes from, but there are wet food options out there too if your dog prefers that.
