I know what you mean about hyperventilating. When Chloe was a puppy I had to give her prescription ear drops and you would have thought I was trying to rip her ear off. It took two of us to do it and sometimes we just had to stop she got so out of control. She would squirm, wiggle, moan, groan, squeal, pant and just about make herself sick. After 4 days we gave up.
