Successful management of the elimination diet in dogs and cats with inflammatory bowel disease (IBD)
Introduction to the elimination diet in dogs and cats
Inflammatory bowel disease (IBD) often requires targeted nutritional counseling to control clinical symptoms, ensure adequate nutrient intake, and compensate for ongoing nutrient losses. An elimination diet in dogs and cats using a hydrolyzed protein source or a single novel protein diet is frequently used for IBD patients Recommended. This article provides a comprehensive guide to successfully implementing such a diet.
A thorough medical history before an elimination diet in dogs and cats
Before initiating an elimination diet, the client should provide a complete nutritional history of the patient, including input from all family members and other individuals who feed the patient (e.g., a housekeeper or caregiver). History forms that can be completed at home are available on the World Small Animal Veterinary Association (WSAVA) website.
The veterinarian or veterinary technician should review the medical history forms with the client upon the patient's arrival at the practice. Open-ended questions help ensure the team is aware of everything the patient eats. Identifying all food sources (e.g., treats given with medication or food scraps from the floor) increases the chances of a successful outcome.

Clear communication during the elimination diet for dogs and cats
Step 1: Gradual transition
The patient should be gradually switched from their previous diet to the elimination diet. The general guideline is:
- Feed three-quarters of the previous diet and one-quarter of the new diet for 3 to 5 days.
- Alternate between equal proportions of both diets for 3 to 5 days.
- Feed one quarter of the previous diet and three quarters of the new diet for another 3 to 5 days.
- Complete transition to the recommended elimination diet.
Step 2: Only the recommended diet
It is important to inform clients that during the elimination diet only the recommended diet should be fed (i.e., no flavor enhancers, sauces, gravies, chewable medications, or treats).
Step 3: Be patient
Patients may experience improvement after as little as 3 weeks; however, for gastrointestinal issues such as IBD, it can take 12 to 16 weeks to see improvement after fully transitioning to the new diet. Clients should be informed that there is no quick fix with elimination diets.
Step 4: Follow-up care
Follow-up care is always important, but especially critical for IBD patients during an elimination diet. A team member should call or email the client two days after the transition to the new diet and then follow up weekly to discuss the transition, any challenges or concerns, and to answer any questions. This follow-up demonstrates support and concern, which increases client retention and the chances of successful dietary management of IBD.
Step 5: Long-term diet
Once the patient's clinical signs have subsided, other foods can be reintroduced, adding only one new protein at a time. If symptoms return, all new foods should be immediately eliminated from the diet until all clinical signs have cleared. It may be helpful to remind the client that a consistently balanced elimination diet is likely to benefit the patient, as it helps control the disease in the long term.

Suitable pet food for elimination diets in dogs and cats
An elimination diet is a targeted nutritional strategy often used for dogs and cats with inflammatory bowel disease (IBD). The goal is to identify and eliminate potential food allergens. This involves using specially formulated foods that contain either hydrolyzed protein or a single new protein source. Here we present the best options for dogs and cats suitable for such a diet, including products from VetConcept.
Suitable food for dogs
Hydrolyzed protein sources
Hydrolyzed protein is produced through a process in which protein molecules are broken down into smaller units that are less likely to be recognized as allergens by a dog's immune system. These diets are especially beneficial for dogs with severe or multiple food allergies.
- Royal Canin Hypoallergenic DR 21This food contains hydrolyzed soy proteins and is specially formulated for dogs with food intolerances.
- Hill's Prescription Diet z/dWith hydrolyzed chicken protein, this food offers a hypoallergenic option that is easily digestible while providing all the necessary nutrients.
- VetConcept Hypoallergenic CanineContains hydrolyzed protein and is specially developed for dogs with allergies and intolerances.
Novel Protein Sources
Another strategy is to feed dogs proteins they have never been exposed to before. These new protein sources significantly reduce the likelihood of an allergic reaction.
- Royal Canin HypoallergenicContains feather protein, which is considered a completely new protein and rarely triggers allergic reactions.
- Hill's Prescription Diet d/dAvailable in variants with novel proteins such as duck and salmon, ideal for dogs with known protein allergies.
- VetConcept Ostrich & PotatoThis diet contains ostrich meat as a new protein source and is particularly suitable for dogs with sensitive gastrointestinal tracts and allergies.

Choosing the right food for an elimination diet in dogs and cats requires careful consideration and consultation with a veterinarian. Hydrolyzed protein sources and novel proteins are both effective approaches to managing food allergies and IBD. VetConcept also offers a range of suitable foods specifically formulated to meet the needs of animals with allergies and intolerances. Working closely with your veterinarian and selecting the right food can significantly alleviate symptoms and improve the quality of life for affected animals.
What are the benefits of feeding food with novel protein?
Food containing novel protein, meaning a new protein source that the animal has not previously consumed, is particularly beneficial in treating food allergies and intolerances. Because the animal's immune system is unfamiliar with the new protein source, the likelihood of an allergic reaction is significantly reduced. Here are some specific advantages and applications:
Advantages of Novel Protein:
- Reduction of allergic reactions: Since the animal has not previously come into contact with the protein source, allergy symptoms such as skin rashes, itching and digestive problems are less likely.
- Diagnostic purposes: Novel protein diets are an effective means of diagnosing food allergies, as they make it possible to identify and eliminate potential allergens.
- Alternative for multiple allergies: If an animal is allergic to several common protein sources, Novel Protein offers a valuable alternative.
Examples of Novel Proteins:
- Kangaroo: Rarely used and therefore a good option for animals with many known allergies.
- Bouquet: Also rare and hypoallergenic.
- Insect protein: A newer and more environmentally friendly alternative that is being used more and more frequently.
What is the purpose of feed containing hydrolyzed protein?
Food containing hydrolyzed protein is particularly beneficial for animals with severe or multiple food allergies, as well as those that do not respond adequately to regular novel protein diets. Hydrolyzed protein is produced through a process in which protein molecules are broken down into smaller units, making them less likely to be recognized as allergens by the immune system. Here are the main benefits and applications:
Advantages of hydrolyzed protein:
- Minimal allergic reactions: The small protein fragments are hardly recognized by the immune system, which greatly reduces allergic reactions.
- Wide applicability: Hydrolyzed diets are suitable for animals with multiple protein allergies and offer a safe nutritional option.
- Improved tolerability: These diets are easily digestible and therefore also well suited for animals with sensitive digestive tracts.
Examples of hydrolyzed protein:
- Hydrolyzed soy protein: Widely used and well tolerated.
- Hydrolyzed chicken protein: A commonly used source in hypoallergenic pet food.
Both novel protein and hydrolyzed protein diets offer valuable solutions for the nutrition of dogs and cats with food allergies and intolerances. Novel protein is ideal for initial diagnosis and for animals with specific protein allergies, while hydrolyzed protein is an excellent choice for animals with severe or multiple allergies. By selecting and using these specialized diets correctly, the quality of life of affected animals can be significantly improved.
