Welcome to Pet Talk!
You'll find that a lot of us here are pro-rescue and adoption, not that we all are against breeding, but we all feel the need to save the animals that have been dumped.
My first question to you is why?
What made you first want to get into breeding?
Is it to make money or is it to better the breed and the bloodline?
From what I've heard, Bulldogs can not reproduce or give birth naturally, you will want to look into every aspect of breeding and keep the dogs health and well being as your first priority.
