I want to ask your oppinion on something during mating. When the dogs have been mounting and flirting and mating but as soon as the dog is about to tie the dam runs like chicken away and stand again and it seems like he is about to finish his work but she prevents them to tie by this behaviour. He has thrusted few times but no tie. Would it be cruel holding her collar so she will not run. She has been flagging for about a week now. Hopefully for reasonable answer.
