Hmmm -
Well, it's not a bad contract overall but #12 really disturbs me. IMO, $1500 for a co-owned dog with 3 breedings back is a bit much. (Actually IMO $1500 for any dog is a bit much unless it is from a long-line of BISS/SOM/DOM champions or is already finished, but the going rates in your area may be higher.)
The only monetary refund I see is if the dog is diagnosed with a "debilitating genetic defect" within 2 years of the purchase date.
This contract also reads to me that these breeders are not screening for Aortic Stenosis, and are not requiring stud dogs to be screened for that or Boxer Cardiomyopathy or Hip Dysplasia.
As for Other Terms, I'd include something about not signing a litter registration that includes in the count any puppies of a color disallowed by the breed Standard (this is a violation of the ABC Code of Ethics -
http://clubs.akc.org/abc//ethics.htm ). Also outline what happens if the required breedings don't take or result in only white puppies or the pups don't survive. I'd imagine you'd take him to the bitch as opposed to the bitch coming to you, and if they're local that's no biggie, but you might want to outline who pays medical bills if the stud is injured while at their kennel for breeding (or, if you will be taking the bitch, who is responsible for her fees while she's there) - most of this is outlined in a separate stud contract but since they're the co-owners, they probably wouldn't use one.
Also, what do they mean by "show the dog for 2 years?" Every weekend? Twice a month? I guess since there's no monetary recourse for not finishing (unless I missed it) it really doesn't matter - but it might come back to haunt you.
The way I see it, if you're going to be getting a puppy or a litter (much less 3) back from a dog you sell, co-owned or not, you should be discounting the purchase price. We got our brood bitch *free* on a co-ownership, the first litter belonged to the co-owner but we got pick puppy from that litter (we also got final choice of stud from her selection of 3-4) - after that she was ours free & clear. (We left the co-ownership out of gratitude & respect, but that was our choice.) This is not your common co-ownership arrangement, and we already had purchased a pet puppy from this breeder and knew her well, but it is an example of the other extreme
But, this is really not a horrible contract, if you're comfortable with them and trust them and think they would be good mentors (and, IMO, if they are very successful in the conformation Boxer community), it might be worth the strings.
I certainly will look at a pic of the pup,
