AJ needs to get appropriate medical care, asap. The chances of an dog up to date on rabies vaccine being infected with the rabies virus from a wild beast in your back yard is VERY SLIM, however, the possibility of the wound site getting infected is very real.
I can tell you from experience that doing the right thing can be disasterous. I have a HUGE mistrust of the "system" - way too many of the "enforcers" are misinformed and will use their authority and outdated inaccurate information in inappropriate ways. My situation involved a BAT that I found in the wash rack of my barn during daylight hours. At the time I was just going on old wives tales about bats and rabies..... so I called my vet who referred me to the health department.
Rabies vaccination is NOT part of our state's rabies protocol for livestock and since my vet couldn't even tell me when the last documented case of equine rabies occurred, I elected to not do the rabies vaccines. But because I found a bat during daylight hours in my barn and tried to do the right thing, the health department planned to quaranteen my entire farm -- all livestock (at that time almost 30 head of horses) INSIDE the barn with the doors closed. Even though I had the bat in hand (gloved hand that is) the health department would NOT send someone out to collect the bat and test it for rabies before shutting down my farm business. You see, it wasn't their responsibility and they couldn't tell me who could/would, but they DID have the authority to quaranteen my entire horse farm and curtail all farm operations. To top it all off, I had only ONE horse in the barn at the time and he was at the opposite end of the barn

.
I was so disgusted with the health department that I hung upon them, and released the bat..... the poor thing apparently FELL from the barn rafters - somthing that I found out later just happens occasionally. More research revealed that although bats can transmit the rabies I could NOT find a single documented case of a rabid bat infecting a horse in the state of Georgia - ever.
The real concern is NOT rabies - especially if your little one is current with vaccinations. The real concern is secondary infectin at the wound site. I wish you the very best of luck with little A.J. I know it was a very scary thing, and if it was a raccoon, you are lucky that A.J. escaped with only a few scratches and bites.
