Excellent food Sunali on 8 July 2021

My two Tibetan Mastiffs enjoy this as a supplementary meal to their raw diet.

Experienced purchaser newfi family on 8 December 2018

We have fed all our newfoundlands on Royal Canin Giant for the last 20 years and they have enjoyed it and have been healthy and fit. The large size pieces is ideal and they eat it at a sensible rate. There is never any change in the product it is always the same high quality. The coat has a nice shine and a rich colour. We are delighted with the product.

Louie just loves it !!!!!!! Jenny on 1 December 2017

Our Blue Great Dane Louie is now just over 2 yrs old and loves Royal Canine Giant Adult Food .He has had the same brand since a puppy just changing the sizes as he has grown..Never a problem with the food or portions..Now feed twice a day.The prices and special offers on the RC make this a good buy. When there are v good offers we usually buy two of the 15kg bags. The delivery is so very quick ,driver always so helpful and the online order no problems.I have always used PetPlanet for many years and will continue to do so. Thank you.

Best food for my boy Dantes Mum on 2 October 2017

Excellent food from royal canin. We fed this to our 3 great Danes for years, now our bullmastiff. He loves it, fills him up easily, costs less in the long run than buying cheaper foods. Always gets comments on his size, shiny coat & how healthy he looks. There is no substitute for giving my dog the best & this is the best by far. Always excellent service & price from pet planet. Wouldn't shop anywhere else for any other product. Top marks!!!
