I just got my 8 week old pit bull yesterday.
I know that she may still be a bit anxious since leaving her mother and her litter, but I think that she may be shaking and trembling so much because something is wrong.
Could there be something wrong with her?
Hi
Yes, there could be something physically wrong that is causing her to behave this way, or it could simply be the stress of leaving the only home and family she's known in her short life.
First of all, you should always have a new puppy checked out by your own veterinarian within 24 - 48 hours of bringing him/her home. You need to be sure that she's healthy and up to date on her puppy shots and deworming.
Secondly, check out my Bringing Home A New Puppy page as it has lots of information on what to expect during the first few days with a new pup.
Hope this helps. Best of luck with your puppy.
