Best dog food on the market.

My GSD has been on Royal Canin food since she was old enough to eat solid food. Her coat is great and I can highly recommend Royal Canin to any and all dog owners.

Quality dog food at a good price

by CKC -

My dogs enjoy this food and it feels very rich, not dry like some other foods we've tried. The Bottomless Bowl seems to be a good deal too.

My Alsatians

by Michael -

Royal Canin Large Dog dry food has been a hit with my two Alsations!! The bites are larger than my previous dry food & they finish the food eagerly!! I did a comparison feeding & the dogs immediately went to Royal Canin! So grateful I made the switch (healthy formulation) & very happy with the speed of delivery with vetshop.com.uk!! Much appreciated...

Great product!

by Hannah -

My two Bluetick coonhounds love hunting around the garden for their dinner and will work their socks off whilst training for this kibble. I get 2x15kg every 6 weeks on subscription and it works really well. They are always on time and if I need to move it to an earlier delivery slot they are super helpful and change things around to suit the need! It is a nutritional balanced meal.

Very consistent in quality. Dogs snaffle it eagerly. We also like the fact that from a puppy, adult and senior stages of life, the product adjust to suit.

I have used Royal Canin for all my dogs for many years now and their overall health has been excellent. This, I am sure, is mostly due to the excellent formulation of their diets.

Excellent Product From A Very Efficient Supplier

by stuart hutson -

our Husky Zeb remains active and healthy on this food and with him having a sensitive stomach its the only one we will remain using. its nice to have a supplier that charges a sensible price rather that being ripped off with high street prices, and have an excellent delivery process. Well done. regards Mr Stuart Hutson factory Manager
