I did phone the vet and asked the Dr his opinion of bringing her in for testing. He said at this point, don't bother. She's eating-has never really stopped and her temp is more near normal, so rather than pick something up there, just wait it out. If her temp was down again and she wasn't eating, then he would be more worried. He said right now the fetus' are implanting so a drop may be normal for her. Her biting may have been because of jealousy at the baby gate/door. I had a baby gate up by the back door. My doorway has three steps down to a small landing that leads to either downstairs or outside. She could see outside, so I put the door back up, and she's been a bit better with the doorway thing. The one girl was petting all of them over the baby gate and I'm thinking Damisi got jealous and went to bite Shadow and hit the girl instead. And Sam (my daughter) was moving all of them away from the baby gate with her leg, and Damisi bit her then, but, again, I'm thinking Damisi thought she was biting at Shadow. She's better with the other dogs if I'm not here, she doesn't snark as much at them. But if I'm here, she wants to be right beside me all the time. Last night/yesterday, she laid in my arms for hours at a time, which is definitely not like her. So, it may be a bit better now with the door up there's not as much anxiety over what's at the back door. I asked the vet about an ultrasound (they do them at 28 days) but he said don't stress her out anymore right now, just to leave it be. I'm hoping to get her eyes done on Nov 13, they are having a clinic then, and I think that should be enough for her to get stressed out about. Hopefully, we have turned the tide now!
