I have to say that if at all possible I prefer to avoid arrangements like this - buying outright is usually far less complicated. I was once offered co-ownership on two bitches by their breeder. She flattered me saying she didn't do this with just anybody. This wasn't exactly true!! Having thought long and hard about this, and whether I wanted these bloodlines in any case, I decided agin. Not only was she wanting me to use her stud dogs when the time came to mate them, but she also wanted pick puppies. Nice - I did all the work, she sweeps in and walks off with presumably, the best.
If you go for this, and the cynic in me suggests that some breeders who have a promising male puppy but no room for another male, will welcome finding somebody to house the dog ......, do GET IT IN WRITING. All the things like vet bills, entry fees, stud fees he might attract and so on. Even with the best of friendships things can go wrong, leading to lots of problems.
By all means use her as a mentor, travel to shows together etc.etc. but for me I'd far rather buy this dog outright. This does rather come under the heading of 'there are no free lunches' you know.
ps Who knows whether there will actually BE a show-quality puppy in this planned litter, or whether by the time he's ready for the ring, he will still be as good!! What then? I guess you could keep your options open, for now. Also I had to home a male I'd kept from an all-male litter. By around 2 he'd started challenging his uncle, big time and try as I did, I couldn't get him to settle down. So I found him a super home with a girl who was experienced in the breed, with 2 bitches. However, as I really didn't know her that well, I decided to co-own him with her. However, as time went on, and I got to know her better, I ended the coowner ship and signed him over to her. It does mean somebody going into the unknown, has time to get to know the new owner and whether they can be trusted!! Especially when it comes to stud rights.
