My friend died and in her will she gave me her dog. Dog is co-owned and now they will not transfer registration to me. I have been dogs handler for 2 years. I have had possession of dog for 3 months. Friend had contract with co-owners that she was to get championship (she did at her expense) and to bring him for stud (she did) they agreed to help offset pro-rate expenses for shows with majors in the amount of 1/2 cost but not to exceed $150 (they never paid her anything). I have emails between my friend and co-owners saying they have no problem with me having the dog. Now they want me to return him for breeding and more confirmation showing. He is now neutered, they know this. Do you have any advice?
