Product Change Notice:       Hill's Prescription Diet i/d Digestive Care Dry Dog Food

Hill's Prescription Diet's i/d Digestive Care range is undergoing  a portfolio reset  across it's products (excluding Low-Fat varieties) 
Existing i/d dry and wet products will have minor formulation changes, and now be categorized as “adult-only”.  This change allows for the new growth stage specific dry diets for puppies and kittens with digestive upsets to be introduced.  The improved i/d recipes are fortified with Hill's breakthrough ActivBiome+ ingredient technology clinically shown to rapidly activate the gut microbiome to support digestive health and well-being.

There are no expected changes to palatability, however with veterinary diets and sensitive pets a 7-10 day feeding transition is recommended to support pets through any adjustments to their diet.

During this time you may receive either variety as the updated products begin to arrive to retailers. Subject to change and stock levels.

  • October 2025 onwards - Cat Wet (canned 156g )

  • "Hills Prescription Diet "
    Posted byDavid Senioron9th Dec 2022

    Our dog loves this food!

  • "Hill's Prescription Diet i/d Digestive "
    Posted bySarena Payneon14th Jun 2022

    I have a mini schnauzer who has a very sensitive gut, that flares up if not on a strict diet plan. This Hills I/d food works for her so well, been on it now for about 4 years. It is always in stock and delivery is super fast!

  • "Immediately effective!"
    Posted byJane Butleron13th Mar 2022

    I have a 3year old Swiss Shepherd who has a sensitive gut. I’ve tried various quality dog foods and yet her stools continued to be overly soft and messy to pick up. I changed to Hill’s Prescription i/d and within a few days her stools were much-improved and firm to collect without being a squishy mess!
