Great food, ATROCIOUS service.

This food is fantastic, my Newfoundland thrives on it, but the price increases in the last year -- first in the form of shrinking bag size by 5 lbs, then by increasing prices by 40+% -- have been EXTREME. Tried to save a few bucks off the bags that now cost $105 (GASP!) by ordering directly through this company, but it has been a nightmare...I've been trying to cancel my autoship for MONTHS and they just keep charging my card and sending me boxes every four weeks. I am going to have to report fraud to my credit card company to get this to stop because their online contact and cancellation methods don't function.

Best kibble for giants hands down.

We've been blessed with two giant breed dogs and this food is hands down the best we could find for them and the only one they've both really loved. The ingredients are far and away better than anything but a raw style diet. And our English Mastiff would only eat this food, she wouldn't even touch anything else. Our Great Dane did prefer the breed specific choice but she doesn't like anything other than Royal Caning and pouts when we try anything else (we had to during the supply chain issues recently).

Amazing for Neapolitans

Ever since I brought my Neapolitan home as a puppy I have fed her Royal Canin, and I have to say, the formulas are the best I've found. The kibble size is spectacular for Neapolitans who have a lot of dewlap to work with. It makes it so easy for my girl to pick up and eat and she loves it! She is also a show dog and breeding dog and Royal Canin makes her look absolutely spectacular. I can only hope they make the giant starter available! If not, I'll use the maxi when my girl is bred.

We LOVE this brand!

We have 2 adult Great Danes, both 3 Years old. We started them off with a recommended large breed puppy food that was not Royal Canin, but they had so much stomach upset that we asked our vet what to do. The blood work and stool check showed no intestinal parasites, so the vet recommended that we look at the food that we were feeding. We went online and looked at the ingredients in many dog food brands and came across Bil Jac. We went with Bil Jac large breed puppy for a short time, but were not satisfied with the results. The Danes still had stomach upset and their coats were dull. Furthermore, the kibble was like rabbit food and hard for them to chew because of the size. We then looked at Royal Canin and saw that they have breed specific formulas and the contents were just what our vet recommended. So we began with the "Giant Breed Puppy" Formula. When our girl became pregnant we switched her over to the "HT 42d" Large Breed, which is for breeding females from the 1st day of heat to the 42nd day of gestation. We then switched her to "Starter Maxi Mother and Babydog" formula which is for Mother from the end of gestation until the end of lactation and puppies from 3 or 4 weeks to 8 weeks of age. Both mom and puppies loved this formula and did extremely well with it. Our veterinarian stated that they were the strongest and best looking puppies that he had seen. We kept mom and dad both on "Giant Breed Puppy" for 18 months as recommended by our vet. Following they both went on "Giant Junior" for another year and finally on to "Giant Breed Adult" We are so pleased with their weight, coat and stool formation. Neither have presented any health concerns and the vet stated that is due to good care and nutrition. So thank you Royal Canin for being a big part of good care for our babies.
