How can you check whether your dog benefits from a hypoallergenic diet?
Key takeaways
- Watch for non-seasonal itching, skin rashes, and hair loss on the ears, paws, groin, or muzzle, since these are the main signs of a food allergy in dogs.
- Digestive changes such as vomiting after eating or diarrhoea can also point to a food allergy, so track them alongside any skin symptoms.
- An elimination diet trial typically runs 8 to 12 weeks using a novel or hydrolyzed protein, with no treats or table scraps allowed to interfere with the results.
- Loop in your veterinarian before starting a hypoallergenic diet and keep them updated as you go, since they can confirm the diagnosis and adjust the plan based on your dog's response.
As dog lovers, we naturally want to ensure that our four-legged friends lead healthy and happy lives. One way to achieve this is by providing them with balanced and nutritious food. However, with the rise in allergies and intolerances among dogs, it can be a challenge to find the right nutrition to meet their needs. Hypoallergenic diets are becoming increasingly popular, but how do you know if your dog will benefit from one? In this article, we look at a number of ways to check whether your dog would benefit from a hypoallergenic diet.
What Are Hypoallergenic Diets for Dogs?
Have you ever noticed your dog suffering from skin rashes, itching, or digestive problems? These could be signs of food intolerance or a food allergy. A hypoallergenic diet may then be a solution to reduce the symptoms.
A hypoallergenic diet is a diet containing foods that are less likely to cause an allergic reaction. This diet can help identify which foods are causing the allergic reaction or intolerance. The diet usually consists of new foods that the dog has not eaten before, introduced gradually to monitor for any reactions.
Keep in mind that a hypoallergenic diet is not always the best solution for all dogs with allergies or intolerances. In some cases, medication may be needed to treat the symptoms and make the dog more comfortable. It is therefore important to consult your veterinarian before starting a hypoallergenic diet.
Symptoms of Food Intolerance or Food Allergy in Dogs
Does your dog suffer from food intolerance or a food allergy? If so, a hypoallergenic diet may offer a solution. This involves using protein sources not normally found in dog food. But how do you know if the diet is working for your dog? In this section, we discuss the symptoms of food intolerance and food allergy in dogs and how you can check whether the hypoallergenic diet is helping.
Symptoms of Food Intolerance or Allergy
The main symptoms of food allergy in dogs are moderate to severe, non-seasonal itching and skin complaints.[1] This often shows up on the ears, paws, groin, armpits, around the eyes, and around the muzzle in the form of itching, hair loss, redness, or bumps. Sometimes the symptoms are more subtle, such as a flaky, greasy coat or ear infections, and gastrointestinal complaints such as vomiting after eating or diarrhoea can also occur. Colitis (inflammation of the large intestine) or an increased frequency of bowel movements can also be symptoms of a food allergy. Some dogs also lick their paws or rub their noses along the ground.
A. Skin-Related Symptoms, Such as Rashes and Itching
One of the most common symptoms of food intolerance or food allergy in dogs is skin-related problems. These can range from rashes to persistent itching. If your dog is constantly scratching or licking its skin, this may be a sign of a food allergy.
B. Digestive Problems and Changes in Stools
Another common indication of food intolerance or food allergy is digestive problems. These can range from mild stomach upset to severe diarrhoea. Look out for changes in your dog's stools, such as their consistency and colour.
C. Other Possible Symptoms That May Indicate Food Intolerance or Food Allergy
There are also other symptoms that may indicate a food intolerance or food allergy, such as chronic ear infections, excessive licking of the paws, and frequent vomiting. If your dog shows any of these symptoms, it is time to consult the veterinarian.
When Should You Consult a Veterinarian?
It is important to consult the veterinarian as soon as possible if you suspect your dog is suffering from food-related problems. After all, our beloved pets cannot tell us exactly what is wrong, so it is up to us to look after them properly. If you notice that your dog is not feeling quite himself after eating, such as experiencing stomach ache, itching, or a rash, these could be signs of a food intolerance or allergy and you should consult a veterinarian without delay.

Diagnosing Food Intolerance or Food Allergy
Open communication with your veterinarian is key so they can get a full picture of what is going on. Tell them everything you have noticed, whether it is itching, stomach problems, or other discomforts your faithful companion is experiencing. Do not forget to mention if anything in their diet has changed.
By sharing all the information openly, you will help the veterinarian make the right diagnosis and prescribe the best treatment for your dog. They are there to help and need your insights to get an accurate picture of the situation.
The Elimination Diet
An elimination diet is a useful tool used to identify food allergies in dogs.[2] This diet involves temporarily removing all possible allergens from your dog's food and gradually reintroducing them to discover which ones cause reactions. The elimination diet is a practical way to find out which foods your four-legged friend may not tolerate well.
A properly conducted elimination diet trial typically lasts 8 to 12 weeks. During this period, your dog receives only the new food, with no treats, table scraps, or supplements that could interfere with the results. The diet usually uses a novel protein source (one the dog has never eaten before) or a hydrolyzed protein, where proteins are broken down into smaller fragments that the immune system is less likely to react to.
Monitoring Your Dog's Reaction to the Hypoallergenic Diet
Once you have identified the allergens that are making your dog feel ill or uncomfortable, it is vital to closely monitor your dog's reaction to the hypoallergenic diet.
Pay close attention to any changes in symptoms such as skin rashes, itching, digestive problems, and other complaints. These changes may indicate that you are using the wrong food or that you may need to combine the food with medication.
Follow-Up with the Veterinarian
Regular follow-up with the veterinarian is vital for evaluating and adjusting the diet. The veterinarian can adjust the diet based on your dog's response and any changes in their health.
By keeping in regular contact with the veterinarian, you can monitor your dog's progress together. The veterinarian has the expertise to assess whether further adjustments or specific nutritional requirements are needed.
