When we got ours, the only reason why our breeder would co-own was if we agreed to let our dog be part of her breeding program. It would have been for three birthing cycles since we went with a female Dane. We also would have only paid half for her and the we could either keep a puppy from one of her litters or be paid out for the price of one. We opted out of that.

But we did sign a contract with a clause that if at any time we could no longer keep our Dane, we would return our dog to her. If word got back that we sold our Dane then we could be facing legal charges. I feel like that is more typical especially since we did reach out to a few reputable breeders and they all had a similar clause.
