Standard American Bulldogs

Well I may get hammered here, Mrs.LousianhogDog I do really like your muzzle length on your dog, and believe you are absolutely correct in your thoughts behind your dogs performance being related to his breathing and recovery and abilities due to that in your dog. One thing we took serious in our dogs and never looked back. At the time were unable to find others with purebred dogs of same type to breed and keep the same phenotype and ended up outcrossing to keep our performance in our catch dogs.
THATS MY OPINION. I like Your DOG! I would seek others that have similiar types of dogs with build straight legs in backgrounds and parentage and grandparent and great grandparents, those mater intensly!
Our main male alsways threw some really Bully dogs when bred to pure AB females, and thats why we outcrossed for consistant "type" long muzzles, straight legs, deep lungs not wide, long back, high hip,long neck angled into shoulders, ect are very important to me in movement and performance

TEMPERMENT- CATCHING ITS ALL A PACKAGE DEAL part of performance,
