I have been babysitting difficult child#1's dog until they get moved. She has been a real pain: ate the cushion on my windowseat, several pillows, the lip off my bottom step, a piece of my bed (the wood part), my bedspread, a chair cushion, etc. However, I love dogs and have managed to cope. When he wanted to bring her here, I pointed out that she was almost old enough to go into heat and I have one male dog that has not been fixed. Not a problem, he said. Ha, ha. Famous last words! She is now in heat and male dog has been enjoying himself. I tried to shut her in my back room, away from him, but she ate a 3' x 2' hole in the door. So..... I know you can take your dog to the vet and get a shot which will abort the supposed puppies. My question is, how much time do you have after the "event" to do it? And would it be pointless if I can't keep them apart? Who knows the details?
