I think my cocker spaniel might have rabies

Question
all of a sudden my 6 month old cocker spaniel is drooling every where it recently started after she got loose from my son while he was walking her. she found her way back home after a couple of hours right now I'm station in Korea what other signs should I be looking for. Please Help

Answer
Your cocker has had her puppy shots, including Rabies.  And there's only one way to get rabies and that's to be bitten by a rabid animal.
So don't worry about that.

What I'm concerned about is she's eaten something that's causing this.
Please have her taken to a vet asap if this doesn't stop fairly quickly.  

Perhaps your son is too young to be responsible for her?  At 6 months they're pretty strong.
