How does an elimination diet work for suspected allergic dogs?

A dog constantly scratching, licking or biting its paws, and suffering from recurring ear infections are common issues whose cause is important to investigate. When there is a suspicion that the symptoms are due to a food allergy or food sensitivity, a structured plan is required to find the right solution. Food sensitivities directly affect a dog's daily well-being. Pinpointing what triggers the reactions requires diligence from the owner, and the most effective tool for this is a carefully conducted elimination diet, which is also recommended by veterinarians.

The purpose of restricting the diet is to calm the dog's body and identify the proteins or other ingredients that trigger the hypersensitivity reactions. Since there is no single, entirely reliable blood test to diagnose food allergies, a systematic elimination diet is the only certain way to proceed. The process requires discipline, but with its help, you can choose a suitable, clinically tested specialized food that provides permanent relief from symptoms.

What are the symptoms of food allergy in dogs?


Symptoms of allergy in dogs can manifest in many different ways and are sometimes confused with other skin diseases or issues caused by external parasites. A typical sign of food allergy or sensitivity is itching, which frequently affects the head, ears, paws, armpits, and stomach. If the dog constantly licks or bites its paws, or rubs its face against the floor, it could be due to a hypersensitivity reaction. Continuous scratching damages the skin barrier, paving the way for secondary bacterial and yeast infections that further worsen the symptoms.

In addition to skin symptoms, food allergy often shows up in the dog's gastrointestinal tract. Symptoms can include loose stools, recurring diarrhea, gas in the stomach, or vomiting. In some dogs, the only symptom is an unusually frequent need to defecate, indicating a mild inflammation of the intestine. Poor nutrient absorption can lower the dog's general condition and make the coat dull.

Veterinarian's recommendation

Always consult a veterinarian before starting an elimination diet. Before changing the diet, it is important to ensure that the dog does not have any underlying, undiagnosed skin or intestinal infections that require medical treatment.

Practical implementation of the elimination diet and choosing the right specialized food


The principle behind an elimination diet requires great precision from the owner. The dog's diet is completely cleared of all ingredients it has eaten previously. Instead, a food is selected that does not trigger any allergic reaction. In practice, you use either a heavily hydrolyzed specialized food or a monoprotein food containing an entirely new protein source for the dog, such as horse or venison.

In a hydrolyzed specialized food, the proteins have been broken down during manufacturing into parts so small that the dog's immune system does not recognize them as allergens. This method minimizes the risk of an allergic reaction, giving the dog's sensitive skin and intestinal tract time to calm down and recover. Such a carefully prepared specialized food is considered the most reliable starting point for an elimination diet.

Steps in an elimination diet

1

Choice of diet: Choose either a hydrolyzed specialized food or a new monoprotein food in consultation with your veterinarian.

2

Strict diet (6–8 weeks): Feed the dog exclusively the chosen food and water. No treats, chew bones, or table scraps may be given during this period.

3

Provocation phase: Reintroduce previous protein sources one at a time into the diet and observe if symptoms return.

Finding a suitable food is easiest by looking at clinically tested options. Products developed for various special needs and to relieve symptoms can be found directly in our comprehensive dog food range. We offer specialized food manufactured under strictly controlled conditions for top security against unwanted raw materials and allergens ending up in the food during the manufacturing process.

Why is strict accuracy crucial for the elimination diet's success?


The biggest challenge with an elimination diet is often everyday mistakes. When a dog has an allergy, its body reacts strongly even to minimal triggers. A very small amount of an unsuitable protein – like a piece of cheese dropped from the table, a flavored tablet, or a treat from a family member – can restart the symptoms. A single exception can irritate the dog's body so much that the entire test period of several weeks must be restarted from the beginning.

According to veterinary medical statistics, a large percentage of elimination diets fail because the dog manages to ingest something not included in the diet. It is therefore absolutely vital that the whole family and other people who interact with the dog are fully committed. Reaching a reliable result and making the symptoms fade away requires everyone involved to strictly follow the agreed rules.

Avoid these hidden sources of allergens during the diet

1

Flavored medications and supplements: Many dewormers, joint supplements, or chewable tablets contain beef or pork flavorings that can disrupt the diet.

2

Table scraps and other pets' food: Dogs quickly find crumbs that have fallen on the floor. Feed the household's other animals in a separate room and vacuum or wipe the floors thoroughly.

3

Eating from the ground during walks: During the walk, the dog can quickly snap up something unsuitable. If necessary, use a basket/muzzle during the investigation period.

How do you proceed after the elimination diet? Provocation and choosing a long-term food


When the period of 6–8 weeks is over and the dog's symptoms have subsided, the provocation phase (or exposure) begins. It is through this phase that you find out exactly which raw materials the dog reacts to. The dog is then controllably given one protein source at a time (such as beef or chicken) for about a week. At the same time, you carefully observe whether any skin or stomach issues return. If no symptoms arise, the dog tolerates that specific raw material.

Once the triggering factors have been identified, you transition to a permanent maintenance food. The goal is to find a balanced, high-quality food that keeps the dog symptom-free. For long-term use, a carefully selected monoprotein food or a hypoallergenic food that supports the skin barrier and maintains balance in the gut is ideal.

Investigating allergy symptoms requires patience from you as an owner. But finding the right food provides a permanent improvement for the vast majority of allergic dogs. When the itching disappears, the skin can finally heal, digestion works normally, and the dog's general condition and energy levels improve significantly. An adapted diet and dedicated care are the most effective ways to support your dog's well-being and give them a symptom-free everyday life.

Support for your dog

How do you ensure the quality of a specialized food?

When choosing a specialized food, quality and purity play a decisive role. By selecting reliable and clinically tested specialized foods, you ensure that your dog receives all necessary nutrients safely without hidden allergens. A correctly chosen diet supports the dog's overall health and contributes to a good quality of life without recurring skin or gastrointestinal symptoms.
