OMG.... what a handsome fella! Look at Curley face.... he is so not happy --- Momma, get him away, he is invading my sleep space!!! LOL What is his name?
I do not know much about GD's, but the breeder I got all my bulldogs from also breed Dane's for many years so I could ask her the questions you have and maybe help you along.
I so LOVE his ears... big and floppy
