Puppy with ear infections

13th Mar 2018
Debra Squires
  • VioVet Customer Since: October 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?

  • Customer Service Advisor

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

3rd Jan 2018
Kaye Smith
  • VioVet Customer Since: July 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

  • Product Developer

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.

My dog is allergic to wheat/turkey and rabbit. Unfortunately she may have serious gut problems as well as reflux so the vet at the animal hospital has instructed me to switch from raw to this product.... Please would you confirm this does not contain the above products? I know maize is from corn but I need to make sure! Thank you

  • Website Content Developer

Hello Nicola,

Thank you for your question.

I can confirm that this food does not contain any wheat, turkey or rabbit. The main protein source of this food is of vegetable origin (soya bean).

I hope this helps.

My dog has been onPurina HA for 2 months, does it contain all the nutrients

My dog has been on Purina HA for 2 months, does it have all the nutrients she needs? Reason I ask is because today she started eating other dogs poo, she never did this before.

  • Non-Executive Director

Purina HA does contain all the nutrients your dog needs in her diet. If she is eating another dog's pooh then maybe she is particularly hungry, or that other dog has a digestive problem and is not digesting its own food properly. Is the other dog perfectly OK? It might have a pancreatic problem or something.

If your dog has a dietary allergy, then Purina HA is likely to be a great help. I am not sure from your email that this is definitely the case, though it is certainly possible. If you try the HA diet then you must not give any other food at all for at least 6 weeks, ideally longer. Then you decide if your dog is doing better. If so, you can keep on with the diet forever. If after 6-8 weeks there is not a significant improvement, this diet will not help. You will do no harm by trying the diet, but it is a big commitment. No treats or anything else, just water and HA. Talk to your vet about it too.

I have a year old female whippet who my vet thinks has a food intolerance.

21st Feb 2015

She has itchy eyes, ears and mouth and chews her feet.I have tried wainrights potatoe and Salmon diet and it made a small difference but after 8 weeks she is still itchy. If I try Purina H A can I wet or dampen it or does it have to be fed dry.

  • Non-Executive Director

You can add water to it, but not gravy or any flavoured liquid. Ordinary tap water (warm or cold) is perfectly OK.

How much should my 2.1kg chihuahua be fed, he also needs to be 1.9 kgs

22nd Dec 2014

He is on HA and gets 1T/D kibble and 1/2 a synovial flex

  • Non-Executive Director

Every dog is different, so it is impossible to predict accurately in advance how much food will be required. However it is very easy to work this out after a while. You need to start off with your best judgment of the correct amount, then see what happens to his weight. If he is overweight, you have been giving too much, so you simply feed less. The absolute truth is in the fact that the correct amount of food to give is simply the amount which produces the correct body weight. More food means a fatter dog, not enough food means a skinny dog. You raise or lower the amount you give to produce the effect you want. It really is that simple. I have four dogs, including 2 neutered labradors and they are all a perfect weight, but only because I restrict what they get to maintain the correct body weight. I promise it will work for you if you do it sensibly, but you must be prepared to be a bit harsh if really your dog needs less food. Good luck!

My german shepherd is allergic to pork beef and lamb,she can't have any foods which have animal fats containing these products or just foods saying animal fats and also can't have any foods that contain meat and animal derivatives,would this food be ok for her?

  • Non-Executive Director

This is exactly the sort of diet which is designed to be given to dogs like yours. Multiple dietary allergies are becoming quite common in dogs and Purina HA seems to work very well for them. You need to feed it to the exclusion of all other foods, at least for a few weeks. It takes a few weeks to become fully effective so you have to be very strict with the food your dog can eat.

Yeast infections

8th Oct 2014

I have been feeding Purina HA to a 12 year old bitch with pancreatitis for over a year. She is now getting recurring yeast infections, mainly ears, is the food contributing to this?

  • Non-Executive Director

It seems unlikely that the diet will be the cause. The HA diet is usually used for dogs which have multiple food allergies and these conditions themselves are probably more likely to be connected with the underlying cause of the yeast infections. The dog's immune system is not functioning perfectly for the HA to be needed in the first place. These conditions are complicated and not fully understood, but the diet really is not likely to be the cause. It is sometimes simply a method of treating some of the symptoms. This can be very useful and a big help, but might not be a complete answer. Regular treatment of the yeast infections might also be something you need to do.

Sore paws - over licking

5th Feb 2014
Penny Storlry

We have a 6 year old Bichon/Westie who has started to chew and lick her paws causing irritation. The vet thinks this might be food intolerance, can the Purina diet help wtih this?

  • Non-Executive Director

It is very possible that this diet could help with your dog. I would say that your dog is probably licking and chewing her feet because of the irritation, rather than the licking causing it. The irritation is presumed to be an itchy feeling which dogs commonly experience when they react to certain proteins in their diet. This can come on at any age, a bit like hay fever in people. One thing we do know is that dogs like this very commonly stop all the licking and itching when they go onto a diet which does not contain any proteins which were present in their previous diet.

The Purina HA is designed specifically for dogs like yours because it is processed in such a way that it contains no large protein molecules. You have to feed the diet (and give water) but nothing else at all for at least 4 weeks, maybe longer. It often takes a few weeks for the itching to subside even after you start a suitable diet.

There are alternatives to the HA food which might work just as well. The most natural diet would be made up of fresh meat or fish of types not found at all in the diet previously (duck, salmon, venison etc) along with a different carbohydrate source (potato, sweet potato, tapioca etc) and a vitamin and mineral supplement which contains no protein. Making this sort of home-made "exclusion diet" is tricky to get right, so most vets recommend Purina HA or a different diet manufactured in the same way. Personally I would certainly suggest you buy the HA, do not give any tit-bits or treats or any other food for 1 to 2 months. Then if all works well and you want to, you can gradually introduce some other foods under your vet's direction.
