HIV and 2 consectutive dog bites

A friend of mine has a dog who began choking and could not breathe. I reached my hand inside the dogs mouth to try to unblock its throat and was bitten. I did not see any blood from my hand at this point. My friend also tried to unblock his throat and was bitten more severely-visibly began bleeding a decent amount. I continued to try to unblock the dogs throat immediately afterward, and may have been bitten again. I did not think about the cuts on my hand at the time, but now I am worried that blood from my friend's wounds that was in the dog's mouth may have entered mine, especially if the dog had blood on its teeth and then bit my skin. There are only a few cuts on my hand. They do not appear to be severe and are mostly shallow, but one or two may be deeper puncture wounds, it is hard to tell. What is the risk of transmitting blood-borne infections like HIV or Hepatitis in this manner? I am not aware of the other person involved having these diseases, but they may not know, or may not have thought to have said anything in the commotion. Does this kind of exposure warrant testing? Thank you.

P.S. The dog was taken to the vet and now doing ok ! :)

Not an HIV concern.

I knew that dog bites were not generally a concern, but did not know if this changed when it involved another person being bitten at the same time-sorry if the question was still unnecessary. Thank you
