Just got back from the vet. They did a full "blood test" along with a urinalisis and a Lyme test. All came back normal. She was a little dehydrated though.
As for the poisoning idea; they said if she had any toxin in her body the white blood cell count would be very high.
They think she is either having seizures or "mania". When I asked about "mania" they basically said anxiety. My "homework" is to catch it on tape; if she does it again they will put her on seizure medication. If she gets better, that is their way of dx it.
She is still not "right"; just not acting her normal self
. As soon as we came home she went right to her kennel (her choice); she doesn't even want to be around us.
Breeder said there is absolutely no current history of seizure in her lines. None of the other puppies are having a problem.
So, it is either a mental "break down", or Complex Partial Seizures. We will have to wait to find out. If it is a "mental" issue; how do I fix it?
