Don't know what to think here...
I've noticed since day one that she "shakes", like she is shivering, but I just figured at first it was nerves being with new people, new place, etc. It's been almost a week and she is still doing it.
Today, I was cooking dinner, and had just put down a bowl of water for her. It was full, and she drank almost the whole bowl to herself. I kept watching her thinking she couldn't possibly keep drinking. Then she looked like she was going to be sick, and I figured she would have to really pee now, so I had my son take her outside. He wasn't outside a minute and he started yelling at me to come out. He said she looked like she was going to throw up. When I looked. She was sitting, but her back was hunched looking. She still had that look like she could be sick. He said she was shaking, so I picked her up and brought her inside. I held her for about 5 minutes (so it seemed) before she finally stopped shaking. She wasn't crying or whining or making any noise.
She drinks a lot, but doesn't eat much. I have even tried to hand feed her just to get her to eat more. She is skinny. When I picked her up, the breeder even said she was small and could use to gain a few pounds. I weighed her and she was only 12lbs! 9 week old Berner! I weighed her a couple days later and she was up to 15lbs.
