Novel protein and hydrolyzed diets are both used to address dietary allergies and intolerances. Novel protein diets are based on proteins that the animal has never eaten before, such as venison for a dog that usually eats chicken and beef. Hydrolyzed protein diets, on the other hand, are chemically altered through hydrolysis to break down protein molecules into their base components, rendering them unrecognizable to the animal's body. This process of breaking down proteins reduces their allergenic potential and can help to eliminate existing food allergens. While novel protein diets are sold over the counter, hydrolyzed protein diets require a veterinary prescription.
Differences between Novel Protein and Hydrolyzed Diets
| Characteristics | Values |
|---|---|
| Definition | Novel Protein: A protein source that the dog has never eaten before. For example, venison if the dog used to eat chicken and beef. Hydrolyzed Protein: A stable protein source composed exclusively of free amino acids and very low molecular weight oligopeptides. |
| Allergies | Novel Protein: 84% to 95% of confirmed food-allergic dogs can be maintained on a commercial novel protein diet. Hydrolyzed Protein: Hydrolyzed protein diets are used to remove existing allergens and prevent recognition by a patient sensitized to the intact protein. |
| Availability | Novel Protein: Sold over-the-counter. Hydrolyzed Protein: Requires a veterinary prescription. |
| Ingredients | Novel Protein: Limited ingredient diets that contain only a small number of ingredients. Hydrolyzed Protein: Contain grains, fillers, and other additives. |
| Treatment | Novel Protein: Used to reset a dog's digestive system without chemically altered hydrolyzed protein. Hydrolyzed Protein: Used to cleanse the organism of existing food allergens and return the immune system's agitation to baseline. |

Novel protein diets are commercially available and can be used to control clinical signs while providing balanced nutrition
Novel protein diets are not created through hydrolysis and are available over the counter. They are based on proteins the dog has never eaten before, such as venison if the dog previously only ate chicken and beef. This type of diet is also known as a single protein source diet, and it is important to note that no protein can be described as hypoallergenic for every dog or cat unless it has never been available to any pet before its release.
Novel protein diets are recommended for longer-term management once a dietary intolerance has been proven. They are an excellent way to "reset" a dog's digestive system without chemically altered hydrolyzed protein. They can be a good option for dogs with food allergies, as they are grain-free, high-quality, and have ultra-limited ingredients, cutting out potential allergens while providing the health benefits of naturally protein-rich real meat.
However, it is important to note that novel protein diets have limitations during the diagnostic period, and it is still possible for a dog to develop a hypersensitivity to the novel diet over time. In such cases, hydrolyzed protein diets may be recommended to remove any existing allergens and prevent recognition by a sensitized patient. Hydrolyzed protein diets are created through hydrolysis, which breaks down protein molecules into their base components (amino acids and peptides), and are available by prescription.

Hydrolyzed protein diets are chemically altered to remove molecule tags that identify the source of the protein
Hydrolyzed protein diets are often used for pets with allergies. The process of hydrolysis chemically alters the protein, breaking it down into its base components of amino acids and peptides. This is done to remove the molecule tags that an animal's body uses to identify the source of the protein. In other words, once a food has been hydrolyzed, an animal can still digest and use the protein, but their body will no longer be able to determine the type of meat it came from. The broken-down molecules are treated as generic, uncategorized proteins.
Hydrolyzed protein diets are often used for elimination trials, especially when a dietary history is uncertain or reveals exposure to multiple proteins. The primary aim of a hydrolyzed protein diet is to remove any existing allergens and prevent recognition by an animal that is sensitized to the intact protein. This can help to reduce or eliminate allergic reactions. For example, in one study, 10 out of 12 chicken-allergic dogs had a significant reduction in allergic reactions when fed a chicken hydrolysate diet.
Novel protein diets, on the other hand, refer to proteins that the animal has never eaten before. For example, if a dog used to eat chicken and beef, a novel protein diet might introduce a new protein source such as venison. Novel protein diets are not created through hydrolysis and are sold over-the-counter, while hydrolyzed protein diets require a veterinary prescription.
While novel protein diets can be effective, there are some limitations to their use during the diagnostic period. Additionally, it is still possible for an animal to develop a hypersensitivity to the novel protein over time. Hydrolyzed protein diets can be a more reliable option for managing food allergies and avoiding aggravating existing allergies, especially in animals with compromised digestive systems.
It is important to note that hydrolyzed protein diets are not the only option for pets with allergies, and pet owners should be informed about all available choices. For example, a novel protein diet based on a grain-free, ultra-limited ingredient dog food can also help cut out potential allergens while providing the health benefits of naturally protein-rich real meat.

Hydrolyzed proteins are used to cleanse the body of existing food allergens and reset the immune system
Hydrolyzed proteins are commonly used to address food allergies and reset the immune system. The process of hydrolysis involves breaking down the peptide bonds of different amino acids that make up a protein. This disrupts the protein's structure, removing existing allergenic epitopes and altering its ability to generate an immune response. This is particularly useful for individuals who have been exposed to multiple proteins and have an uncertain dietary history.
The primary goal of a hydrolyzed protein diet is to eliminate existing allergens and prevent recognition by individuals sensitized to the intact protein. This is achieved by reducing the size and structure of the protein through enzymatic hydrolysis, which decreases or eliminates its antigenicity. By disrupting the protein, hydrolyzed diets aim to prevent mast cell degranulation and enable individuals with hypersensitivities to ingest the hydrolysate without adverse reactions.
Hydrolyzed protein diets are well-suited for individuals with food allergies or hypersensitivities. They are easy to use, readily available, and cost-effective options for managing these conditions. The most common sources of protein for hydrolyzed diets include soy, chicken, casein, and liver. These diets have been shown to significantly reduce allergic reactions in dogs with confirmed allergies to the parent protein, such as chicken, soy, or corn.
In addition to addressing existing food allergies, hydrolyzed protein diets can also help prevent the development of new allergies over time. As the immune system remains "primed" for an allergic response, hydrolyzed diets can reduce the risk of allergies to additional proteins by providing a hypoallergenic option. This is especially beneficial for individuals with compromised digestive function, as larger peptides and proteins can contribute to the development or exacerbation of food allergies.
Hydrolyzed proteins are also used in infant formulas to prevent allergic diseases and manage allergic manifestations in infants. Cow's milk-based hydrolyzed formulas, for example, have been shown to reduce atopic dermatitis in high-risk infants who are not exclusively breastfed. Additionally, hydrolyzed wheat products are commonly used in the food and cosmetic industries due to their increased solubility and functionality.

Novel protein diets are limited-ingredient diets, whereas hydrolyzed protein diets are not
Novel protein diets and hydrolyzed protein diets are both used to address dietary allergies and intolerances in dogs and cats. However, they differ in their approach to ingredient selection and preparation.
Novel protein diets are limited-ingredient diets, meaning they contain only a small number of ingredients. These diets introduce proteins that the dog or cat has never eaten before, such as venison for a dog that previously ate chicken and beef. By using a protein source that is new to the animal, novel protein diets aim to reduce the likelihood of an allergic reaction. These diets are often grain-free and based on high-quality, ultra-limited ingredient dog food, providing the health benefits of naturally protein-rich real meat. Novel protein diets are sold over-the-counter and do not require a veterinary prescription.
On the other hand, hydrolyzed protein diets are not limited-ingredient diets. Hydrolyzed protein diets use enzymatic hydrolysis to break down protein molecules into their base components, amino acids, and peptides. This process chemically alters the protein, reducing its size and molecular weight, thereby decreasing its allergenic potential. Hydrolyzed protein diets can be used to address specific health challenges, such as food allergies and digestive issues, and are often prescribed by veterinarians. These diets are not limited to a specific number of ingredients and may still contain grains, fillers, and other additives. Hydrolyzed protein diets are recommended for elimination diet trials, especially when the dietary history is uncertain or when there has been prior exposure to multiple proteins.
While novel protein diets offer a viable way to control clinical signs of allergies and provide complete and balanced nutrition, they have limitations during the diagnostic period. In contrast, hydrolyzed protein diets are effective in reducing allergic reactions, as evidenced by studies showing significant improvements in dogs with confirmed allergies to chicken, soy, and corn.
In summary, novel protein diets are limited-ingredient diets that use new protein sources to reduce the chance of an allergic reaction, while hydrolyzed protein diets are chemically altered to reduce allergenic potential and are prescribed to address specific health challenges.

Hydrolyzed protein diets are prescribed by veterinarians to address specific health challenges
Hydrolyzed protein diets are often prescribed by veterinarians to address specific health challenges in pets, particularly food allergies. Food allergies in dogs can manifest as dermatological issues, gastrointestinal (GI) problems, or a combination of both. To diagnose a food allergy, veterinarians perform a dietary elimination trial, followed by a food challenge using the patient's previous diet or specific food ingredients.
Hydrolyzed protein diets are effective in managing food allergies because they involve breaking down protein molecules into their base components, amino acids, and peptides, through a process called hydrolysis. This breakdown of molecules eliminates the tags that allow a dog's body to identify the source of the protein. As a result, the dog's body can still digest and utilize the protein without recognizing it as a potential allergen.
The primary goal of a hydrolyzed protein diet is to eliminate existing allergens and prevent recognition by a sensitized patient. Additionally, it aims to disrupt the proteins to such an extent that there are no longer any antigens capable of triggering an immune response. This approach can help prevent mast cell degranulation, which is a typical response to an intact protein.
Hydrolyzed protein diets are particularly useful when a pet's dietary history is uncertain or when they have been exposed to multiple proteins. These diets are also beneficial for pets with compromised digestive function, as hydrolysis enhances digestive efficiency. For example, studies have shown that when dogs were fed soy protein hydrolysates, their small intestinal absorption rate increased threefold compared to when they were fed intact soy protein.
While hydrolyzed protein diets are a viable option for addressing specific health challenges, they are not the only choice. Pet owners should be well-informed about hydrolyzed protein and alternative diets to make the best decisions for their pets' health.
