My daschund is heat and chewing & humping on everything. There is a throw that she like to lay under, but now chewing it to pieces . Is there anything to calm her down until her cycle is over. Please help I'm beside myself.

Try giving her melatonine. It's a natural herb that will help calm your dog down.

I hope your bad experience with a dog in heat urges you to get her fixed. Not only will her personality be better, but she will also be less likely to develop breast cancer or pyometra.
