Boy that really sucks! She should be okay... sometimes smaller dogs just get really knocked out when they get both vaccs at the same time for anywhere from 3 - 7 days. She may be lethargic and go off her feed for a few days also.
The really bad thing though, if they don't have an immediate reaction, is that the vaccines can't do as good a job when given together as they do when given separately. Their immune system can't make as many antibodies because it's busy trying to handle both vaccs instead of just one. That is what causes them to be lethargic too. I think it's more the Rabies though, cause even given separately mine are always a bit more 'off' for a few days after getting it.
Thanks for sharing though... my new rule is: dogs stay in the room with me for everything except surgery!
And I'm doing titers from now on too.
