Purina Hydrolyzed Dog Food: A Comprehensive Review

Before we get into the details of the review, it’s essential to understand what hydrolyzed protein dog food is. Hydrolyzed proteins are proteins that have been broken down into smaller pieces – or ‘pre-digested’ – to a size that the immune system is less likely to recognize and react to. This type of diet is beneficial for dogs with certain dietary sensitivities or allergies.

Purina’s Take on Hydrolyzed Protein Diet

Purina, a renowned name in pet care and nutrition, offers a range of hydrolyzed protein diets under their Pro Plan Veterinary Diets product line. These diets are specifically formulated to minimize adverse food reactions and are often recommended by vets for dogs with digestive or skin issues.

Ingredients and Nutritional Value

A prime example is the Purina Pro Plan Veterinary Diets HA Hydrolyzed product. The main ingredient in this dog food is hydrolyzed soy protein isolate, which is a highly digestible protein source. Also present are essential vitamins, minerals, and other nutrients, ensuring a balanced diet for dogs. However, being vegetarian, this product may not appeal to all dogs, and owners have reported varying reactions from their pets, ranging from enthusiasm to reluctance.

Consumer Experiences and Reviews

Given the specific nature of these diets, it’s no surprise that reviews and experiences are diverse. Some dog owners have praised Purina’s hydrolyzed diets for significantly improving their pet’s skin conditions, gastrointestinal issues, and overall quality of life. They found that the diet helped reduce their dogs’ symptoms related to food allergies, leading to less itching and more comfort.

On the other hand, some pet owners expressed concerns about their dogs’ acceptance of the food, with a few reporting their dogs refusing to eat it. Some owners also reported a worsening of symptoms, though these cases appear to be in the minority.

Veterinarian Opinions

Vets often recommend Purina’s hydrolyzed protein diets for dogs with food allergies or intolerances. However, it’s important to note that while these diets can be a vital part of managing these conditions, they’re not a one-size-fits-all solution. Each dog is unique and may respond differently to different diets.

Is Purina Hydrolyzed Dog Food Right For Your Dog?

If your dog suffers from food allergies or intolerances, a hydrolyzed protein diet like the ones offered by Purina could be beneficial. However, it’s crucial to consult with your vet before making any significant changes to your pet’s diet.

Hydrolyzed Dog Food: The Science Behind It

Hydrolyzed dog food works on the premise of mitigating allergic reactions. A dog’s immune system reacts to large protein molecules it deems foreign. By hydrolyzing, or breaking down, proteins into smaller particles, the immune system is less likely to recognize these particles as allergens. This hydrolyzation process, while sounding complex, essentially makes the protein easier to digest and less likely to trigger an adverse response.

Formulation of Purina Hydrolyzed Dog Food

Purina’s hydrolyzed dog food utilizes soy as the primary protein source, which is hydrolyzed to reduce allergenic properties. The formula also includes corn starch and partially hydrogenated canola oil preserved with TBHQ, a common food preservative. The presence of these ingredients may raise eyebrows for some pet parents due to the ongoing debate about grain and non-animal proteins in dog food. However, the formulation is designed to be hypoallergenic, focusing on minimizing allergenic potential rather than aligning with popular feeding philosophies.

Purina’s hydrolyzed diets also include beneficial supplements. For instance, omega-3 and omega-6 fatty acids support a healthy coat and skin, while various antioxidants contribute to overall health. The diets are fortified with vitamins and minerals to ensure they meet AAFCO nutrient profiles, meaning they provide complete and balanced nutrition for dogs.

The Vet’s Perspective

Veterinary professionals often recommend hydrolyzed diets like Purina’s when they suspect food allergies. These allergies typically present as skin issues, such as itching, redness, and hot spots, or gastrointestinal issues like vomiting and diarrhea. The hydrolyzed diet serves as both a diagnostic tool and a treatment in these cases. If the dog’s symptoms improve while on the diet, it supports the suspicion of a food allergy. It’s a process of elimination, with the diet acting as a starting point.

However, transitioning to a hydrolyzed diet is not always smooth. It’s important to gradually introduce the new food to avoid gastrointestinal upset and increase the likelihood of acceptance. Some dogs may be hesitant about the new food, so patience and persistence are key.

Practical Considerations and Cost

One important thing to note is the cost associated with Purina’s hydrolyzed diets. These are typically more expensive than standard commercial diets due to the specialized formulation and processing. The cost can be a limiting factor for some dog owners. However, if the diet proves beneficial for a dog’s health and wellbeing, many owners find the cost justified.

Feeding Instructions and Monitoring

Feeding instructions for Purina’s hydrolyzed diets are similar to other dog foods. Portions are based on the dog’s weight, with adjustments made for life stage, activity level, and health status. Regular monitoring and vet check-ups are important when feeding a hydrolyzed diet. The vet can monitor the dog’s progress, manage any adverse reactions, and adjust the feeding plan as needed.

What Dog Owners Need to Know

While hydrolyzed diets like Purina’s have proven beneficial for many dogs, they aren’t a magical cure-all. They’re a tool to manage a specific health issue, not a standard diet for every dog. Not all dogs will require or benefit from a hydrolyzed diet, and it’s essential for dog owners to discuss any dietary changes with their veterinarian. With proper management and vet guidance, hydrolyzed diets can significantly improve the quality of life for dogs with food allergies.


In conclusion, Purina’s hydrolyzed protein diets are an effective tool for managing food allergies and intolerances in many dogs. However, every dog is unique, and what works well for one may not work as well for another. Always consult with your vet and monitor your dog’s reaction when introducing a new diet.

Despite some reported drawbacks, the benefits of Purina’s hydrolyzed diets, such as reduced allergic reactions and improved digestion, are substantial. This product remains a reliable choice in the world of hypoallergenic dog diets.


FAQ 1: How does Purina Hydrolyzed Dog Food compare to other brands?

While Purina offers a range of hydrolyzed protein diets, other prominent brands like Royal Canin and Hill’s Prescription Diet also offer similar products. The main difference lies in the protein source and the degree of hydrolyzation. For instance, Purina primarily uses soy protein, while Royal Canin may use poultry or fish proteins. Also, the flavor profiles and palatability can vary between brands, impacting acceptance by the pet. It’s critical to consider your dog’s individual needs and preferences when choosing a brand.

FAQ 2: Are there any side effects of feeding my dog Purina Hydrolyzed Dog Food?

While the hydrolyzed diet is generally safe and beneficial for dogs with food sensitivities, some dogs may experience initial gastrointestinal upset during the transition period. It’s also important to remember that each dog is unique, and what suits one might not suit another. It’s essential to monitor your dog for any adverse reactions, and if any occur, consult with your vet promptly.

FAQ 3: How quickly can I expect results after switching to a hydrolyzed diet?

The time it takes to see an improvement can vary greatly depending on the dog and the severity of their symptoms. Some dogs may show improvement within a few weeks, while others may take several months to fully benefit from the dietary change. Consistent feeding and patience are key during this period.

FAQ 4: Can I give my dog treats while they’re on a hydrolyzed diet?

Yes, but it’s crucial to ensure that the treats are also hypoallergenic or align with the hydrolyzed diet’s principles. Purina and other brands offer hydrolyzed treats that can be used without disrupting the dietary management plan. Avoid treats that contain non-hydrolyzed proteins, as they can trigger allergic reactions.

FAQ 5: Can I switch back to regular dog food once my dog’s symptoms have improved?

It’s not typically recommended to revert back to the original diet once a food allergy has been diagnosed. Doing so could cause the allergic symptoms to return. Instead, the hydrolyzed diet should be considered a long-term solution to manage your dog’s food allergy. However, this is a decision that should be made in consultation with your veterinarian based on your dog’s health and well-being.

FAQ 6: Is Purina Hydrolyzed Dog Food suitable for all breeds and ages?

Purina’s hydrolyzed diets are designed for dogs of all breeds and sizes. However, you should consider your dog’s life stage when choosing a product. Some products are specifically formulated for adult maintenance, while others are suitable for all life stages. It’s always recommended to consult with your vet to determine the most appropriate diet for your dog’s specific needs and life stage.

FAQ 7: Can a dog with no food allergies be fed Purina Hydrolyzed Dog Food?

While Purina Hydrolyzed Dog Food is specifically formulated for dogs with food sensitivities or allergies, it can be fed to dogs without these issues. The diet is nutritionally balanced and provides complete nutrition. However, considering its higher price point compared to regular diets, it may not be a cost-effective choice unless necessary for managing a medical condition.

FAQ 8: Can Purina Hydrolyzed Dog Food help with my dog’s digestive issues?

Many dogs with food allergies experience digestive symptoms like vomiting, diarrhea, or increased flatulence. By reducing the likelihood of an allergic reaction to dietary proteins, Purina’s hydrolyzed dog food can help manage these symptoms. However, if your dog has persistent or severe digestive issues, it’s crucial to consult with a vet for a comprehensive diagnosis and treatment plan.

FAQ 9: How long does a bag of Purina Hydrolyzed Dog Food typically last?

The duration a bag lasts will depend on the size of your dog and the quantity you’re feeding daily. For instance, a 25-pound bag can last a medium-sized dog of about 50 pounds approximately one month if fed according to the manufacturer’s recommendations. It’s always important to follow the feeding guidelines provided by the manufacturer and adjust as necessary based on your dog’s age, weight, activity level, and overall health.

FAQ 10: What makes hydrolyzed protein different from regular protein in dog food?

In hydrolyzed protein dog food, the protein has been broken down into smaller pieces, often referred to as peptides. This process is designed to reduce the likelihood of the dog’s immune system recognizing the protein and reacting negatively to it. On the other hand, regular protein in dog food is in its whole form and may be identified as a threat by the immune system of dogs with food allergies.

FAQ 11: Is Purina Hydrolyzed Dog Food grain-free?

Purina’s Hydrolyzed dog food is not grain-free. It contains corn starch as the primary carbohydrate source, and it uses hydrolyzed soy protein as the primary protein source. Despite the ongoing debate about grains in pet food, they are not inherently bad for dogs unless your pet has a specific grain allergy, which is relatively rare.

FAQ 12: What should I do if my dog refuses to eat Purina Hydrolyzed Dog Food?

Transitioning to a new diet should be done gradually, usually over 7-10 days, to increase acceptance and reduce digestive upset. If your dog still refuses the new food, you can try warming it slightly to enhance its aroma or adding a bit of the hydrolyzed wet food (if available) to make it more enticing. Always consult your vet if your dog continuously refuses to eat the new food, as they may need to consider alternative diets or methods.

FAQ 13: Is Purina Hydrolyzed Dog Food beneficial for skin conditions?

Yes, Purina Hydrolyzed Dog Food can be beneficial for dogs with certain skin conditions. Some skin issues in dogs are linked to food allergies, which this diet is designed to address. By reducing the potential for allergic reactions, the diet can alleviate symptoms like itching, redness, and inflammation associated with food allergies.

FAQ 14: Can I use Purina Hydrolyzed Dog Food for weight management in my dog?

Purina Hydrolyzed Dog Food isn’t specifically designed for weight management. If your dog needs a diet for weight control, Purina and other brands offer therapeutic diets specifically formulated for this purpose. It’s crucial to consult with your vet about the best dietary approach for managing your dog’s weight, as they can provide personalized guidance based on your pet’s unique needs.

FAQ 15: Do I need a prescription to buy Purina Hydrolyzed Dog Food?

Purina’s hydrolyzed diets are often labeled as Veterinary Diets, meaning they are typically used under the guidance of a veterinarian and may require a prescription. This ensures that the diet is appropriate for the dog’s health status and is used correctly to manage the intended health issue.

FAQ 16: Is Purina Hydrolyzed Dog Food appropriate for a puppy?

While the hydrolyzed diet can be used for dogs of all life stages, it’s important to check the product labeling. Some products are specifically labeled for adult maintenance, meaning they may not have the appropriate nutrient balance for puppies. Always consult with your veterinarian to ensure the food meets the nutritional needs of your growing puppy.

FAQ 17: Can I cook for my dog instead of using Purina Hydrolyzed Dog Food?

Home-cooked diets can be a viable option for some dogs, but they require significant planning and nutritional knowledge to ensure they are balanced and complete. It’s difficult to create a homemade diet that replicates the benefits of a hydrolyzed protein diet. If you are considering a home-cooked diet, it’s essential to work closely with a veterinarian or a veterinary nutritionist to ensure your dog’s dietary needs are adequately met.

FAQ 18: Does Purina offer canned options for the Hydrolyzed Dog Food?

Yes, Purina does offer a canned/wet version of their hydrolyzed dog food. For dogs that prefer wet food or for those needing additional hydration in their diet, this can be a great option. It can also be used as a topper to increase the palatability of the dry kibble.

FAQ 19: Can Purina Hydrolyzed Dog Food help with ear infections in dogs?

Food allergies can sometimes manifest as recurrent ear infections in dogs. In these cases, a hydrolyzed protein diet, like Purina Hydrolyzed Dog Food, can help manage the underlying allergy and thereby reduce the frequency of ear infections. However, it’s important to address active infections and any other contributing factors with your vet.

FAQ 20: Is Purina Hydrolyzed Dog Food made in the USA?

Yes, according to Purina, their Pro Plan Veterinary Diets including the hydrolyzed diets are manufactured in company-owned facilities in the United States. However, it’s always a good idea to check the packaging for the most accurate and up-to-date information.
