I have recently been to an Amstaff specialty in Australia. I was appauled by the standard of dogs. It was like being at a pony/horse show!
Correct hight for an Amstaff is 18 to 19 inches at the shoulder (Male).
Most of the dogs stood atleast 25 inches at the shoulder, I'm sorry but these dogs are not mastiffs but are a terrier and should move with style and grace.
Breeders need to take a hard look at the standards and breed to them before the Amstaffs of Australia become a joke world wide.
