Sometimes males in my main breed will appear to go to sleep in the tie, lying across her back but not 'turned'. I've never had one actually lie down. Ouch! If there's pain involved when he does this, you may have to prop him up during the tie, so he can't. If you saw a mating in my breed, you'd know how much 'propping up', usually the bitch, with him on top - double ouch for the handler - has to be done. If we weren't there to assist, I do believe the breed could die out! We did have one who did his own thing - he hated anybody to interfere!! He was rare!
How would there be a premature release? Once tied, they are tied in the fullest sense of the word, and to be released before the dog has 'gone down' would certainly involve pain, and potentially injury to either or both.
" it is down to her to release him though." Not as far as I'm aware - he won't be able to part with her until HE goes down.
