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.

Best food for my boy
Dantes Mum
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!!!

My boy loves it
My rescue dog came from Romania in February this year a four year old St Bernard cross From his time on the streets eating a piece of bread if he was lucky and whatever food he could find in discarded rubbish his digestive system was not good I tried various products without success for the first five weeks gentle introducing him to each one and decided it was time to phone a friend She has Great Danes and she suggested trying Royal Canine Giant dog food and to my delight he reached a turning point and with the large nuggets it helped him to slow down his eating and digest it properly I am so pleased to have found the great delivery service of pet planetcouk I am a very happy lady with one happy dog thankyou x
