Thank you all for your quick replies. And yes, it is " a bit" hot here in Dallas
Can't wait 'till morning to take her to the vet. I have a feeling that she is ok, but have to know for sure, so I can stop worrying. My husband said whatever happens tomorrow, he is not giving her back, she already loves her. Me on the other side, I am not so sure what would I do if she has serious health issues.
We had a German Shepherd who died at the age of 7 from kidney failure and a cat who died at the age of 5 from heart desease. I don't think I can go thru that kind of pain again.
I also thought that is kind of weird from the breeder to recomend antibiotics, and there is no way I would give it to a dog without vet prescription.
She ate very good today too, and seems overall very happy and playfull.
Will keep you updated, and thanks again for your replies.
