Hydrolysed Dog Food vs Raw Feeding – Different Approaches for Sensitive Dogs with Allergies

Many dog owners searching for hydrolysed dry dog food are trying to help dogs with:
- itchy skin
- digestive issues
- recurring ear problems
- loose stools
- food sensitivities
- fussy eating
One commonly searched example is Purina Pro Plan Veterinary Diets HA Hypoallergenic Dry Dog Food.
These dry, hydrolysed foods are designed to support dogs with suspected food sensitivities using a very different nutritional approach to natural raw feeding or cold pressed food.
At Wild Tails – Raw Food Specialists, we believe every dog is different and there is no single feeding approach that works for every dog.
What Is Hydrolysed Dog Food?
Hydrolysed dog foods, such as Purina Pro Plan Veterinary Diets HA Hypoallergenic use proteins that have been broken down into extremely small fragments designed to reduce the chance of the immune system recognising them as allergens.
In the example of Purina Pro Plan Veterinary Diets HA Hypoallergenic Dry Dog Food, the producers avoid an intolerance to a particular meat by having no meat in the product at all. The main ingredients listed are Corn starch, hydrolysed soya protein, minerals, coconut oil, sugar and others… but no meat.
Raw Feeding & Natural Ingredient Approaches
Raw feeding takes a very different approach.
Instead of heavily processing proteins, raw feeding focuses on meat based meals with:
- clearly identifiable ingredients
- minimally processed meat
- ground bone
- offal (typically nutrient rich liver, kidney)
- vegetables
- natural superfoods
Many owners prefer this style of feeding because it retains the high meat content but they can clearly see exactly which protein source their dog is eating.
If their dog is allergic / intolerant to Chicken for example, they can choose Duck, Beef, Venison, Salmon etc instead. A careful process of elimination is key to identifying and eliminating from the diet any ingredient which triggers a reaction.
Tip: Use ready-made, single protein raw meals (often called Pure), changing every 4-5 days. Find more help on starting a raw diet at Wild Tails – Raw Food Specialists here.

Ingredient Philosophy
Hydrolysed diets and raw feeding use completely different nutritional philosophies.
Hydrolysed diets focus on reducing immune reactions by heavily processing proteins into tiny fragments.
Raw feeding focuses on using natural ingredients with minimal processing and clearly identifiable protein sources.
Different dogs may respond differently to each approach, which is why personalised feeding advice can be so valuable.
Stool Quality & Digestion
Different feeding styles can affect digestion and stool quality differently depending on the individual dog.
Many raw feeders report:
- firmer stools
- smaller stools
- reduced waste volume
- improved appetite
- shinier coats
- fewer anal gland issues
Other owners may prefer the convenience or consistency of dry hydrolysed dog food.
Every dog responds differently and feeding choices should always suit the individual dog and owner lifestyle.
Cold Pressed Food – A Middle Ground Option
For owners wanting a less processed alternative to hydrolysed or traditional kibble (dry biscuits) without feeding frozen raw food, cold pressed food can offer a useful middle ground.

Cold pressed food uses gentler processing methods than traditional kibble and often contains much higher meat content with clearly identifiable ingredients.
At Wild Tails, one of our most popular options is Wild Pet Food.
