I have a young bitch bred this way but I don't think she is gonna work to any decent standard as she broke her leg 3 month ago nearly and will have screws and a plate in for good but even though she looking good on it and I let her have a run off the lead the other day she eemed fine just a little sore next morning but a working dog takes so many knocks bangs tumbles I will just be happy to get the odd rabid with her but I going to keep my eye out for another. Bred like this just hope I can get one like her as she is / was just a running jumping machine and a real pleasure of a dog to own so i
