American Rotties tend to be much bigger than their German cousins.
In Germany, a dog isn't eligible for registration till he is full grown, and reg is denied if the dog exceeds size and weight limits, among other factors.
Bobeaser's beautiful boy is no doubt of some American breeding, and is undoubtedly as healthy as he looks :)
But, even after OFA screening of parents, hip dysplasia can occur spontaneously in some litters, or can actually be caused by growing too fast in some dogs.
Most Rottie breeders try to keep the pups from adding too much weight too fast as they grow.
If this gorgeous boy added his weight slowly, and in a controlled manner, there is no reason to assume he is dysplastic merely because of his size.
Nice dog, Bobeaser!
