I just read this story on FB of a bully baby dying from abuse during a Petco Training Class. I guess the puppy was barking at another pup, so the trainer used the leash to pull the pup by the collar... long story short the pup died of injuries to it's trachea. Everyone responded w/the same lecture... why would a so-called trainer not tell the owners to get a harness for their puppy? Or why on earth did the trainer pull the puppy's front legs up in the first place?!! I'm sure a lawsuit is pending... but you are correct that the owner has to do his homework to understand the needs of the breed!
