PURINA® PROPLAN® VETERINARY DIETS Canine HA Hypoallergenic is a complete hypoallergenic veterinary diet for the diagnosis and management of food allergies in dogs of all ages, including puppies. Some dogs may suffer from food allergy, which can cause skin discomfort and/or digestive upsets.

PPVD HA is a true hypoallergenic diet specially formulated with a single protein source and purified carbohydrate source and, in addition, the protein has been broken down (hydrolysed) into very tiny components that are too small to cause an allergic reaction. Such hydrolysed diets are recognised as the best type of food to use during an 'elimination diet trial' when trying to diagnose (or rule out) food allergy. During such a trial it is important that your dog is fed no other food or treats.

PVD HA is also useful for dogs with severe bowel disease such as IBD as it is particularly highly digestible.

  • Single hydrolysed protein with low molecular weight to help avoid allergic responses.
  • Purified carbohydrates sources to help avoid allergic responses.
  • With omega-3 fatty acids to help maximise the natural anti-inflammatory process.

He seems to enjoy them and if its the only food he can have then we will have to make this work. He is on measured amounts and it seems to be working to keep his dietary problem in check.

My Irish Terrier loves this food. Was always a grazer but wolfs this down. Her stools are harder now and I am waiting to see if it stops her getting ear infections… fingers crossed.

Q & A

Below are some recent questions we've received regarding PRO PLAN VETERINARY DIETS HA Hypoallergenic Dry Dog Food, including answers from our team.

25 August 2021 at 7:23pm

Suitable for 9 month old Toy breed?

Greg McDonald

I’ve been advised to look into this food as my pup has had repeat bouts of bad guts from 8 weeks old. Bland diets of fish and potatoes clears him up. We then gradually introduce kibble and wet food (AVA, Lilly’s Kitchen, Royal Canin) but eventually somethings triggers a reaction causing him to have severe diarrhoea.
Our Vet suggested this - I’m just conscious that it is for 12months plus.
Any advice on this or another product will be appreciated.

  • VioVet Staff

I recommend following your vets advice. This diet is best suited to adult dogs but it is safe for a pup to eat it and there are no anallergenic versions of puppy diets on the market currently unfortunately. Your vet or Purina themselves will be able to advise on an appropriate feeding regime for your puppy.

Can you recommend a hydrolysed dog food suitable for a one year old hypersensitive blue Staffie?

Hydorolysed dog food

Can you recommend a hydrolysed dog food suitable for a one year old hypersensitive blue Staffie? She has been on the HA Hypoallergenic Dry Dog Food but now refuses to eat it as we think she is bored with it. MUST be hydrolysed according to our vet.

  • VioVet Staff

There are other brands of hydrolysed anallergenic diets you can try. Royal Canin Anallergenic and Hills Z/D are both suitable options. Both are completely anallergenic, similar to Purina HA.

My vet has advised purina pro ha, can I feed her fully on this from day one or do I still have to go through the moving over the 10 days from old food to new ?

  • VioVet Staff

This is a complete diet and can be fed as the only food for your dog. I recommend following your vets advise on feeding. If they have not provided any then you should transition slwoly, over 3 days or so. This is just to prevent your dog turning their nose up to the new diet. Once onto the Purina HA it must be the only food fed (no treats/scavenging etc) for it to be effective.

Dog had really bad diarrea


My dog had bad diarrea vets told me to feed her this HA she was on chicken veg and sweet potatoes as only thing she could keep in my question is do I have to slowly mix small amount into her chicken veg and potatoes or just put her straight on the food for her weight and size

  • VioVet Staff

You should slowly transition any food to prevent your dog rejecting the new food. If your dog is not very fussy then you can do this over just one day, but if they can be fussy then I advise 10% of the new food and 90% of the old for the first day, increasing by 20-30% each day.

Anal gland problems


Could this help my puppy with Anal Gland problems?
Thank you

  • VioVet Staff

This depends on the cause of the anal gland issues. If there is an underlying allergy to it then Purina HA can help by ruling out a food allergy. However food allergies can show as scooting/itching of the rear but rarely show as physical anal gland problems. If your dog has anal gland issues then increasing deitary fibre is a better choice, our own brand ReguTum FibreCare can help with this. I also strongly advise you following your vet's advice regarding the treatment of the anal gland problems, sometimes there can be underlying infections or impactions.

can you get this in wet food.

  • VioVet Staff

Unfortunately this food only comes in a dry kibble form. You can get a wet hydrolysed protein (anallergenic) diet from Hills though, this is Hills Z/D. I would run any dietary changes past your vet first though if they advised you go on the Purina HA in the first place.

Frenchie Allergic to Everything


I have a 3 year old frenchie, he is allergic to all meats, fish, dairy & grains, would this food be suitable?

  • VioVet Staff

Yes this food is perfect for your dog. The diet is 'hydrolysed' meaning it is specially processed so that your dog cannot react to it, no matter what the original protein source is. This food is safe for use in the long term or as part of a food trial when investigating the cause of your dog's allergies. If you need more information on food trials then please contact our customer services on [email protected].

Puppy with ear infections

Debra Squires

  • VioVet customer since 2017
  • From: Hertfordshire, United Kingdom

Vet has recommended a hypoallergenic food such as hills or Purina, but hills has said theirs is not suitable for a growing 5month old puppy (old English sheepdog).....would this support her growth/joints etc?

  • VioVet Staff

Hi Debra,

Thanks for your question.

I have spoken to Purina who say that the HA food would be fine to feed your puppy. You would just need to adjust the feeding amounts and feed slightly more to allow for her growth.

Hope this helps.

Dog allergic to Soyabean

Kaye Smith

  • VioVet customer since 2014
  • From: North Yorkshire, United Kingdom

My dog has various food allergies and is currently suffering from vomiting and inappetence. Would a dog allergic to Soya bean oil be okay to eat this food as the soyabean is a hydrolysed protein

  • VioVet Staff

Hi Kaye,

Thank you for your question.

As the soya protein has been hydrolysed, it has been broken down to the point that the body will not be able to recognise it as an allergen, so they will be safe to eat this food.

I hope this helps.
