not had any problem with my dogs when bitchs are in season or my stud dog,no change tempertment.but all my the dog were laid back and have lived with bitches so they get to know untill the day was right to mate a bitch.my dog stay with the girls untill day 10 and back with them day 19..
but some owners can not afford the total price of a dog so a dog on loan{this in the dog world word term}may suit them better.and the dog is only go to be away for a couple of hours or a day or two at the most for stud work not like a bitch on loan where she go back to the breeder up to 2 weeks before the the puppies are due to when the puppies go to their new homes,
i am loaning my puppy to my sister in law on the contract that i have her back once a week for trainnig and on breeding terms as well. but i am luckly she only lives 2 miles away.so i will be see her weelky so she still know me and my dogs.plus i am doing the ame with a boy puppy to.
some breeder do this like in our breed the gene pool low so we got to keep back a good bitch and dog to keep the lines and breed going.
