Helps keep urinary crystals and infections at bay

by Cheryl -

Helps keep urine crystals away for my elderly spaniel who suffered an enlarged prostate and urinary infection. He loves the taste and it is available in a weight management variety. Although more expensive than standard kibble, its worth it to help maintain his urinary tract.

Good value

by Duncan Dicks -

All urinary care dog foods are a bit more expensive, but this is in the same ballpark as the price I pay for other food, and well worth it to avoid the health problems he's had. A pity they don't do these products vegan.

Excellent product in every way

by Janet -

Very good service at an excellent price. Unlike most dried dog food, our dog absolutely loves the taste of this one so there’s no waste. She eats her meals so quickly with this diet that the food is gone almost as fast as I can put it in her bowl. Apart from being recommended by our vet for our dog because of her urinary condition I would buy this because she loves it so!

20/2/2021 6:36 AM

A great dog food from a great supplier

by Janet -

This is a regular prescription order for our cockerpoo’s diet dry dog food. She absolutely loves it so there’s no waste and it’s usually disappeared from her food bowl within what feel like seconds. Service, delivery and price are all excellent from this website.
