> And with some sensitive males, being put off eventually may put him off, period
Actually a male being allowed to work out when a bitch is ready and when she has had enough teaches him to be an accurate stud dog. the most experienced male rarely bothered to mate the bitch when not ready and also were quite happy to leave off once the bitch was no longer interested.
My mentor (over 50 years in the breed and known for reliable studs) always liked a bitch to come early (say day 8) and allow the pair to meet and the dog gauge her reaction, (of course they were supervised), if her reaction was negative the dog either left her alone (some young ones need a bit of telling) or the bitch was removed if distressed, or pestered.
By the time the more natural courtship was complete the pair were relaxed in each others company, and mating took place.
At the matings I have been present at (where the dog came to stay or I stayed at stud owners home) the pair didn't even need separating except when unsupervised, so most matings took place first thing after morning ablutions, and then they were set for the day happy just to be in each others company (if at home along with my other girls).
A friends dog came to me for all his matings, as she owned another male, he was six before siring his first litter (I had tried him as a maiden with my too domineering bitch, and he gave up on her), and got every one pregnant over his two years of use, including one that had been tried twice before, but never succeeded in being mated.
We could avoid all this testing travelling etc if we just allowed a more natural approach to the whole mating thing without this expectation of presenting a bitch and having her mated when we want within minutes. That sort of approach encourages the dog to assume a bitch presented must be mated there and then or she will be taken away, and being held perhaps encourages this.
The matings I have supervised or assisted in, the handlers did nothing until mating was in progress, discreetly steadying the bitch so she didn't move while the dog turned himself, and then stopping her from fidgeting too much during the tie, or in one of my own stopping her from trying to turn turtle once the tie was made.
I have helped at a mating with a large guarding breed where there were 4 people present, the bitch didn't even lay eyes on the male, eh was walked onto her, two people helped him turn. I found it quite distasteful and over clinical.
I boarded a bitch going to the same male, as studs own bitches would not have accepted her in the house. The bitch was sweet and easy going and had been happily playing trains with my lot.
Stud owner arrived and I suggested she simply let him off lead with her in my dog area (easy to intervene if needed). this time a little play and flirting lead to a lovely natural mating with both very happy. We only approached once the dog had reached the ladder climbing stage in case he needed help and to steady the girl, neither was actually needed we just gently had a hand on her chest while he got his leg around.
