Nice food

Have always feed Iggy Royal canin, He always clears his bowl, his coat is very healthy and he's had no health issues, I have tried other brands but he won't eat it all, so I stick to this.

My dog reared on raw, then onto wet meat prefers this!

My female dogue de bordeaux was reared on raw food, then onto wet food. She never really thrived on either diet. I bought RC giant and she loved it. Clean bowls after every meal and wanting more. Something she's never done before. She now looks absolutely amazing, she's a great healthy weight, everything about her is so much better. It shows that giving the proper nutrients they need is better for them than fancy natural diets

Leonberger heaven!

I tried my Leonberger - now 2.5yrs old - on many different dog feeds & he was basically happy on them but after asking my vet which one she would recommend, this came out on top. From the first bowlful he was hooked! He is in top form & loves his Royal Canin Giant! He chews each piece & makes far less mess with the giant pieces! This will be my default choice for every dog I am lucky to have in my life! By the way - Simba agrees with my comments!🐾

Best kibble for very large dogs!

My rescue American Bulldog is thrilled with this food. Always licks the bowl clean; he tends to be fussy but he loves this food, and the size of kibble means he must chew his food rather than inhaling it. His coat is great, and we have had no gastrointestinal upsets since starting him on RC. I feed this along with some bits of raw meat as toppers and enrichment, and will continue to do so for every dog I own!

Kibble too big for a fast eater

I have been feeding Royal Canin to my Newfoundlands through all their life stages for over 15 years now and they are doing very well on it. However, I just started to feed my 20month-old Newfoundland on Giant Breed and the very large kibble gives him bad indigestion as he eats rather fast and doesn't chew very well. Soaking the food doesn't work because the kibble doesn't absorb water very well.

Ideal for Bullmastiffs

This was suggested by his breeder, and a friend who fed his Great Dane on it to a record age. We used puppy, Junior and now adult, and he is in immaculate physical condition, a good lean 68kg. We sometimes slip in some Butcher’s Tripe to vary it.

Best for Newfoundlands

Feeding only Royal Canin to my 2 newfies since 8 weeks old first giant puppy then giant junior and now adult giant, the dogs have amazing teeth, coats no allergies, dry stools and zero health issues would highly recommend this food

Rottweiler and Company perfecto

I have always fed my dogs on RC and now with my Rottweiler it’s perfect, she loves it and looks brilliant on it and the bonus is straight to your door with no issues trying to lug giant bags of food.. zooplus is a great company albeit some things are maybe pricey but great quality all round and no issues with returns! Will always use zooplus and RC Giant ..

Fantastic product

Have fed seven Great Danes on this without problems. Only one had to be transferred onto another product because of sensitivity Would recommend this to anyone who owns a large breed

THE ONLY FOOD FOR GREAT DANES

I have rescued Great Danes for over 20 years and there is no food better than Royal Canin Giant. My dogs have never looked better, less visits to the vets and prevents bloat. I would highly recommend this product and is worth every penny.

Saw a Great Dane through to double figures

Fed my Great Dane this all his life, he made it to ten years old in good health to the end. Now feeding an Irish Wolfhound the same, again very healthy.

Excellent all rounder

My Labrador Rosie is now 2 years old, she has been fed Royal Canin puppy and then adult dog food since she was weaned, she has a glossy coat, boundless energy and is in excellent health. I would not consider changing her food under any circumstances.

Two cocker spaniels

Both love this food and as cockers can sometimes have delicate stomachs I'm pleased to say this has not been a problem with either. Empty bowls every time. Healthy, active and happy dogs.
