What Causes Allergies and Itchy Skin in Dogs?
Allergies and itchy skin can come from several directions, and diet is one of the most common and most overlooked causes. Here are the main culprits worth ruling out first.
-
Common protein allergens like beef, chicken and dairy
Common proteins like beef, chicken and dairy appear in most mainstream foods and are among the most frequent triggers for allergic reactions in dogs.
-
Ultra-processed food, fillers and additives
Ultra processed food often contains fillers, additives and preservatives that can irritate sensitive skin and worsen existing allergic responses over time.
-
Environmental allergens and atopic dermatitis
Environmental allergens like pollen, dust and grass can trigger atopic dermatitis, a common skin condition that causes ongoing itching and discomfort.
-
Gut imbalance driving inflammation
An out of balance gut can drive inflammation throughout the body, often showing up as itchy, irritated skin rather than digestive symptoms.
Why Single Novel Protein Meals Help Itchy Dogs
5 Hounds meals use single novel proteins and are free from the common allergens and additives found in many mainstream dog foods.
Choose from kangaroo, goat, fish or venison, proteins your dog is far less likely to have encountered or reacted to before.
Our recipes are free from common allergens, fillers and additives, reducing the chance of ongoing exposure to known irritants.
Omega 3 fatty acids help support a stronger skin barrier and healthier coat, addressing skin health from the inside out.
Synbiotic gut support helps calm inflammation linked to an out of balance gut, which can contribute to itching and irritation.

The best kind of progress
Since changing Rosie’s food to 5 Hounds by Dr Will, we’ve noticed such a wonderful improvement. Her itchy ears have settled down so much, and she seems much more comfortable and happier.It’s been such a relief to see her scratching less and finally getting some comfort. We know we’re still on the journey, but seeing this positive change gives us so much hope that we’re on the right track.Nothing makes us happier than seeing our beautiful girl feeling better. Fingers crossed the improvements continue, and we can keep her healthy, comfortable, and itch-free.
5 Hounds has been a life saver
5 Hounds has been a life saver for our Chester. We used to say that Chester was allergic to life! He suffered itchiness, hair loss, anal gland issues and then we found 5 Hounds! Chester’s coat is beautiful, he rarely scratches and his poops are perfect now. He absolutely loves delivery day and can be slightly impatient with waiting for a bag of food to defrost, but I can safely say that every flavour is devoured. He loves it and we love that it’s turned him back into our healthy boy. Thanks Dr Will!
10/10
We LOVE 5 Hounds. The best food, easy to order and the Team are always so quick to respond and offer advice. Having a dog with severe allergies, 5 Hounds has been a game changer for us and I’m very grateful to Dr Will for the help and advice he gave us when we first transitioned to 5 Hounds. Highly recommend!
The itching stopped
I've spent a lot of money at the vets for injections to help my kelpie with his itching, nothing worked until I put him on 5 Hounds. His coat is so dark, full and shiny, no itchy skin.
Dog Food for Allergies FAQs
What is the best dog food for dogs with allergies?
What is the best dog food for dogs with allergies?
The best option is usually a fresh, gently cooked diet built around a single novel protein, such as kangaroo, goat, fish or venison, with no common allergens, fillers or additives. Simpler ingredient lists make it far easier to identify and avoid whatever might be causing a reaction, which is the first step towards genuine, lasting relief for your dog.
Can changing my dog's food stop them itching?
Can changing my dog's food stop them itching?
If the itching is diet related, switching to a single novel protein free from common allergens and fillers can make a real difference. It will not resolve itching caused by fleas, environmental allergens or other medical conditions, so it is worth ruling those out with your vet if a food change alone does not bring noticeable improvement.
How long does it take for a food allergy to clear up after a diet change?
How long does it take for a food allergy to clear up after a diet change?
Most dogs need a strict elimination diet of six to eight weeks before a genuine improvement becomes clear, since it takes time for existing allergens to fully clear the system and for skin and coat to recover. Sticking to a single protein with absolutely no treats, scraps or flavoured medications during this period gives the most reliable and accurate result for your dog.
What is a novel protein and why does it help allergy prone dogs?
What is a novel protein and why does it help allergy prone dogs?
A novel protein is simply one your dog has rarely or never eaten before, such as kangaroo, goat or venison. Since allergies develop through repeated exposure, a novel protein is far less likely to trigger a reaction than common options like beef or chicken, making it easier to identify existing triggers and avoid new ones.
Is grain free dog food better for itchy skin?
Is grain free dog food better for itchy skin?
Grain free alone does not guarantee relief, since most food allergies in dogs are actually triggered by protein sources rather than grains. What matters more is avoiding common allergens and choosing a single novel protein with a simple, transparent ingredient list, rather than focusing on grains as the main factor behind persistent itchy skin and irritation.
When should I see a vet about my dog's itchy skin?
When should I see a vet about my dog's itchy skin?
See your vet if itching is severe, persistent or accompanied by hair loss, hot spots, recurring ear infections or open sores. A vet can help rule out fleas, environmental allergens and other medical conditions, and can guide you through a proper elimination diet if food is suspected to be playing a role in your dog's symptoms.
