Re: How many of you take your females???
What Chris said about the chance of pregnancy.
I generally do not take mine to class when they are in heat. I have so many that my trainer lets me sub in a different one when one goes in heat. This gives some of the older dogs three weeks of classes.
So when I have a bitch in heat, I let them live a life of leisure.
Dogs will get interested, try to sniff her and probably be a bit distracted, but unless you are training in SAR with both dogs off lead and able to go a distance, there would be no way people would not recognize and stop a mating from taking place in a class.
At the same time, you do not want to do ANY off lead work with your bitch at this time in an area that is not secure. It is not just dogs that want to procreate. Bitches can and will do anything to go after them, this includes climbing or leaping fences. Places that were 100% secure before might not be now. It is really not worth it to take chances. She will not make good decisions at this time. Her hormones may override your recall command, and then she is out there with the very real possibility of being run over or shot besides the possibility of becoming with puppies.
