The odds of that dog having rabies is slim to zero. I wouldn't put my child through those series of shots if it were me. How many times did I nick myself skinning raccoons, opossums and muskrats as a kid when I ran a trapline? Countless times, and here I am.
Has there been any confirmed rabies infections in Genesee county this summer, and if yes, what species was it and what was the location? I see a few fox around that look pretty skanky but I think that's just a mange infection. The fox aren't acting aggressive or unusual.
With a dog bite, I'd be more worried about a simple infection turning into something much worse like a MRSA infection than rabies.
