Hi BigBlueTyson
I am assuming you are a registered breeder, who is going to show your boy and do all the relevant health and temperament testing on your dog before breeding?? And if he doesnt turn out, desex him? Just having a quick look on the dogzonline breed profile for staffordshire bull terriers there are a few hereditary diseases that responsible breeders test their dogs for (PHPV, PPSC, Distichiasis, and HC and DNA for L2-HGA and Hereditary Cataracts).
There are more than enought dogs suffering from preventable hereditary diseases because BYB and unresponsible registered breeders, looking to make money dont test their dogs before breeding. Please do the right thing.
