I'm bringing her in today - in four hours.
Yesterday after I posted I noticed a very slight hobble on her. I just knew something was up with her back right leg. Then this morning - it is a limp. She is unstable and doesn't want to put her weight on it. she is still crying when she gets up and is lifted.
My guess is that the constipation might be caused by the antibiotic she is on - don't think it is related to her other problems - but that this is what could be the onset of hip dysplacia. Of course I don't internet diagnose her ... never.
I hope her vet can get to the bottom of all this. Poor little thing - so soon in life and she has all this discomfort. It's not fair.
She is sleeping comfortably right now. Wish us luck everyone.
