I am looking to breed my Boxer, where do I start my research?

i started by talking to breeders i found online and ones that advertised pups in my local paper...i even talked to my vet a lot about breeding...your vet would know more about it then anyone...i breed pomeranians and pomchi mixed...and in 2011 will be breeding golden retrievers and english golden retrievers...i talk to breeders online a lot about the breeds i'm breeding...we email each other back and forth all the time...made a lot of friends that's breeders online...i don't breed by kennel club breed standard...
