Hello, I'm Dr. Kara. I have over 20 years of experience as a veterinarian and I'd like to help with your concerns about your dog's exposure to a wood chuck and then you eating food that she had licked.
There are several reasons that it is very unlikely you have been exposed to or may become infected with Rabies.
Woodchucks are not a species that is commonly infected with Rabies. When they do become infected they usually die pretty quickly and are unlikely to be healthy enough long enough to expose other animals.
Rabies is a very slow growing and reproducing virus. When an animal is bitten the virus needs to travel through tissue along nerves and make its way to the salivary glands, reproduce there, and then be released in the saliva. That cannot possibly happen within 24 hours.
Rabies is a virus that does not live outside the body for very long. The infected saliva needs to be injected into tissue via a bite. The virus sitting on food and then being eaten and exposed to stomach acid would kill the virus.
I can understand that you are concerned, and you may want to call your physician for reassurance, but on a microbiology level I don't believe that you had any exposure.
If your dog is current on her vaccination for Rabies then it is even more unlikely that any exposure occurred.
You do want to confine your dog for at least 2 weeks to watch for any symptoms. You may wish to revaccinate her now for Rabies just as a precaution if she is current on her vaccine for Rabies, or at the end of her confinement if she isn't current on her Rabies vaccine.
Best of luck with your pup, I hope this information helps.
