Mainly, i'd just like sadie to have the mothering experience
Have to be honest with you here. She doesn't need the mothering experience, and she won't be missing anything if she doesn't have a litter.
Breeding takes a lot of time and effort (and MONEY!!!!!) to do things right. If you don't have your dog's papers and pedigree IMO that is a HUGE strike against breeding the dog. The fact that you are no longer in contact with the breeder also does not help your case. Why?
The pedigree doesn't just list the dogs behind your dog. The pedigree holds vital information such as health and temperament. And since you are highly unlikely to know any of the dogs beyond your dog's parents, and you definitely don't KNOW the parents like a breeder should know the parents, such a breeding should not take place.
A breeder should be able to tell you who produced what, both good things and bad things. Who produced weak toplines? Who produced strong, correct temperament? Who produced dogs with hip dysplasia or EPI? All very important things you need to know.
Also, if you cannot correctly state your dog's color (Your dog is black and tan), that's something else you really need to learn about before you breed.
You need to be studying the genetics of this breed. The health issues, the coat colors, the coat lengths. You need to study the AKC and SV standards. You need to understand what you're looking at both anatomically and genotypically (that goes back to pedigrees).
Breeding is SO much more than having a "nice family dog" and finding an intact male that is also "a nice family dog".
I've got a wonderful titled intact boy here that is also an active service dog. He's 6 years old. I've had many offers not only to buy him, but to breed him as well.
I always say no.
Just because he is intact (and even titled) doesn't mean he is of the quality necessary to reproduce.
