How to choose
How we tested

With so many options to choose from, selecting the best dog food for allergies might feel a little overwhelming. We understand that you want the very best for your pup, which is why we’ve called in our team of real pet owners to put seven to the test.

If you suspect your dog has a food allergy, some of the common symptoms include ear infections, vomiting, itchy skin, and diarrhea. Since there are various allergens, it’s important to understand exactly what they're reacting to before you start switching up their diet.

We recommend getting a diagnosis from your vet who will be able to help your dog transition into their new diet smoothly. To learn more about food allergies in dogs, this guide can help you.

It’s important to find the right food for your dog, especially since "6% of all skin diseases in dogs and 20% of all allergic dermatological signs in dogs have been attributed to adverse food reactions", according to the Canadian Veterinary Journal.

Once you’ve worked out the allergens to avoid, it’s time to pick your dog food. Not sure where to start? Keep on reading for our guide to the best dog food for allergies, tried and tested by our experts' dogs. We also called in vet Dr Joanna Woodnutt to get the lowdown on some ingredients and what to consider before you choose.

Best overall

1. Merrick Limited Ingredient Real Salmon & Sweet Potato Dry Dog Food

Best overall

Specifications

Item form: Dry food
Age range: Adult
Allergen info: Free from grains, dairy, soy, eggs, corn, wheat, gluten

Reasons to buy

+
Contains flax seed and fish oils
+
Limited protein sources

Reasons to avoid

-
Hard to store and not resealable
-
Slight fishy smell
Buy it if

✅ You want a dry food that has limited ingredients: Thanks to its limited protein source, there are less chances of a food allergy. 

Don't buy it if

❌ You don't want any odors: Since this food has a slightly fishy smell and the packaging is not resealable, you might want to avoid this one if smell is a big issue for you. However, you could always invest in a storage bin or bag clip.

The bottom line

🔎 Merrick Limited Ingredient Real Salmon & Sweet Potato Dry Dog Food: Containing omega 3 and 6, this food is great for helping with inflamed skin. If your dog is prone to allergies, this might be the one for you due to its limited protein sources that reduce that risk. 

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

2. Wellness Simple Limited Ingredient Diet Grain-Free Turkey & Potato Formula Canned Dog Food

Best limited ingredient

Specifications

Item form: Wet food
Age range: Adult
Allergen info: Grain-free, limited ingredient

Reasons to buy

+
Grain-free
+
One protein source
+
Contains source of omega 3

Reasons to avoid

-
Not suitable for dogs with turkey allergy
-
Turkey cross-reacts with chicken allergies
-
Not suitable for dogs with lamb allergies
-
Lamb cross-reacts with beef allergies
Buy it if

✅ You're looking for wet food with limited ingredients: If your dog isn't a fan of kibble, they'll probably prefer this one a bit more. Since it contains only one protein source, there's less chance of a food allergy. 

Don't buy it if

❌ Your dog has an allergy to turkey or chicken: Stay clear of this one if your dog has either of those allergies. Since turkey cross-reacts with chicken, it might not be suitable for your pooch. 

The bottom line

🔎 Wellness Simple Limited Ingredient Diet Grain-Free Turkey & Potato Formula Canned Dog Food: If your dog doesn't have an allergy to turkey or chicken, this budget-friendly food could be perfect for them. It's grain-free, has limited ingredients, and contains ground flaxseed (renowned for its anti-inflammatory properties). 

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

3. Annamaet Original Sensitive Skin & Stomach Dry Dog Food

Best premium food

Specifications

Item form: Dry food
Age range : All ages
Allergen info: Free from corn, wheat, soy and legumes

Reasons to buy

+
Contains anti-inflammatory menhaden oil 
+
Contains prebiotics

Reasons to avoid

-
Not suitable for lamb or chicken allergies
-
Lamb cross-reacts with beef allergies
-
Expensive
Buy it if

✅ Your dog has sensitive skin: It contains menhaden oil, an omega-3 essential fatty acid that's well-known for its anti-inflammatory properties for the skin.

Don't buy it if

 You're on a budget: This dog food has lots of benefits, but it's the priciest option on this guide and will set you back $4.25/lb (for a 12lb bag). 

The bottom line

🔎  Annamaet Original Sensitive Skin & Stomach Dry Dog Food: There are lots of reasons to love this dog food, from its anti-inflammatory ingredient to its delicious flavor (according to Duke the dog). If you don't mind spending a little more, it's a great option.

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

4. Hill's Prescription Diet i/d Digestive Care with Turkey Wet Dog Food

Best vet prescribed food

Specifications

Product form: Wet
Age range: Adult
Allergen info : Veterinary diet

Reasons to buy

+
Contains omega-3 and omega-6 fatty acids
+
Also available as dry food

Reasons to avoid

-
You need a vet prescription which might make things more expensive
Buy it if

 You're looking for a vet-prescribed dog food: You won't be able to buy this without a vet prescription, which gives you peace of mind that it's the right match for your dog.

Don't buy it if

❌ You're looking for a budget option: Whilst this isn't the most expensive on the list, you will need to pay for a vet appointment to get a hold of this dog food which is another added cost. 

The bottom line

🔎  Hill's Prescription Diet i/d Digestive Care with Turkey Wet Dog Food: It might not be the most convenient way to buy your dog food, but getting your vet's stamp of approval is always important when transitioning onto a new dog food - especially if they have an allergy or sensitivities. 

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

5. Purina Pro Plan Adult Sensitive Skin & Stomach Salmon & Rice Formula Dry Dog Food

Best on a budget

Specifications

Item form: Dry
Age range: Adult
Allergen info: No corn, no wheat, no soy

Reasons to buy

+
Free from corn, wheat and soy
+
Contains omega-3 and 6 fatty acids

Reasons to avoid

-
Packaging is not resealable
Buy if

You're on a budget: This dog food ranks at number one on this guide in terms of affordability, costing just $0.14/oz for the largest size. 

Don't buy if

You want something easy to store: Unfortunately, the packaging is not resealable which might make it trickier to store. However, you could buy a storage bin or bag clip to fix this problem.

The bottom line

🔎 Purina Pro Plan Adult Sensitive Skin & Stomach Salmon & Rice Formula Dry Dog Food: Containing oatmeal for digestion and fish oil for omega-3, this dog food is great for maintaining a healthy coat and is gentle on the stomach.

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!”

✅ You're looking for a gluten and grain-free option: This one's a winner if your dog suffers from gluten and grain intolerances. Say goodbye to uncomfortable symptoms. 

Don't buy it if

 Your dog has a chicken allergy: Chicken is a common allergen so you'll want to avoid this one if your pup is allergic. 

The bottom line

🔎 Vital Essentials Freeze-Dried Raw Chicken Entree Mini Nibs Dog Food: If your pup struggles with a gluten or grain intolerance, you can be rest assured that they won't face their regular symptoms, as this food doesn't contain either. What it does contain is herring oil; an omega 3 which is known for its anti-inflammatory properties for the skin and coat. 

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).
