when would be the best time to start breeding my pup ay what age?

Dave we need a lot more information about your bitch, if she is still a pup you have plenty of time so come back to us and tell us more about her and what you hope for when you do breed her, I don't mean pups, we all hope for that, I mean are you breeding because you need another pup or because you want to show and are looking to improve on her or for some other reason. You will also need time to find a suitable stud, your bitches breeder should be able to help with that because they will know what will suit your bitch. Still as I said plenty of time. Please get back to us. Ja:)kie
