I have a Great Dane... He's had Canidae from day one. He loves it. Great food IMO!
Dane's stop growing between 2 and 3 years of age. My dane has already reached 36 inches from paw to back, he weighs somewhere in the 170+ lbs range and has the most amazing coat. The kicker is he's only 18 months old. So he's pretty much the size of an adult dane, and he's still got plenty of growing to do. He's not in anyway over weight, as a matter of fact he looks like he could use a meal.
Needless to say.. I'm a firm believer in Canidae.
