@beth314 You don't need to go to any expense. An old towel is perfectly OK and she may not even leak much. This is a case of taking things easy and just relaxing.
@DonC said We had a female who, the first time she went into heat, carried on and on and on. So much so that we started singing the Annie Lennox song "I Need A Man".
We had one who screamed for a man from about Day 4 into her season. Not only that, but she wouldn't eat. She went on and on, discharging paler and paler, and in the end I took her to one of our own line (line breeding on Donner) - not really expecting anything. It was probably Day 22 or so.
Result was four beautiful puppies, two tris and two reds and they all lived to be well over 14 - our own Trouble making 16.5. We had to keep a tri bitch !
But - the power of a good man - she starting eating normally and stopped screaming from the moment I got her home after the mating. She really had been screaming for a man !
