>and I'll be suffering separation anxiety
I'm smiling at that! Whenever I've had a bitch to stay, and the owner is worried about their bitch pining, I always say the same thing. You will miss her far more than she will miss you. I always take visiting bitches to bed with me, I then know exactly how they are acting.
I've only ever had one bitch that was distressed and she was demented. The owner was not happy that I phoned her to ask her to collect her bitch. She wanted to know if I could just make her bitch mate! Her bitch wasn't ready, but I was then told that the bitch slept in kennels with her GSD's. The poor thing was missing her mates, not her owner.
However, I took my bitch to be mated, and it was a long old drive, so we agreed that she would stay for a week. Bear in mind, I had already been shown the stud dog owners bedroom and dog beds by the side of her bed. And stayed a few hours, so knew my bitch was totally happy. Yet, as soon as I arrived home, I phoned to see if my girl was ok, as I was already missing her. :-)
