Product details

Hill's Prescription Diet Canine z/d is a hypoallergenic dog food that's designed specifically for pets with food intolerances.    

How it works   

Hill's Prescription Diet Canine z/d is a complete dry dog food mix that helps to limit your pet's contact with ingredients that could be causing their intolerance. It's an effective way to control your pet's allergies. 
The mix uses protein in the form of hydrolysed chicken pieces. Hydrolysed protein is broken down into small pieces, making it harder for your pet's immune system to detect. Your pup can also digest smaller pieces more easily, meaning they can get the most nutrients out of every bite of food.    
This dry mix contains naturally occurring antioxidants that help to keep your pet fit by fighting off free radicals. This is especially important when their immune system is low due to an intolerance. Diet Canine z/d is also rich in fatty acids to keep your pet's coat and skin in good condition.    

Key benefits  

  • natural ingredients cut contact with likely culprits of allergy 
  • complete hypoallergenic dry food 
  • fatty acids restore the condition of their skin and coat 
  • hydrolysed protein that's not detected by your dog's immune system 
  • antioxidants keep their immune system fighting fit. 

When to use it  

If you think your dog might have a food intolerance, there are a few common symptoms that you can look out for: they might become lethargic, vomit or have diarrhoea. If you notice these changes in behaviour, take them to the vet as soon as possible for a diagnosis and treatment.    
You can exchange your pet's regular daily food to Hill's Prescription for life. Before switching, give them Canine Diet z/d for a trial period of up to eight weeks. If they're still showing signs of intolerance, take them back to the vet.

  • My lucky day
    My dog is 12 years old and has been on Hills ZD since he was six months old which I had to order and collect from the vets.

  • Helped my dog so much!
    This food looks very much like recovery food. It does however help with any stomach issues. My dog has been helped so much with this food which the animal hospital suggested I try him on. He is incontinent and this food ensures his stools are quite firm. His stomach issue appears to be under control with the use of this food.

  • Excellent Food
    My 9 year old dog has been exclusively on this food for about six weeks - on the vets advice. He has suffered from chronic colitis for most of his life. For the first time in years he is now off all medication and no sign of colitis.
