Is this a flea bite??

Factual Questions
1

I debated whether or not to make a new topic after a thread I made asking if this was a flea. I decided to start a new one since it is a different topic. Anyway, I found a few fleas on one of my dogs a week or so ago. I’ve been maniacally cleaning my house and vacuuming since. I’ve been combing my dogs and not finding anything. I’m not finding flea dirt on my sheets, either. However, I just found this on one of my dogs due to his fur being wet. When I examined his wet fur around his front leg, this is what I found:

It’s like a small, fluid filled sac. There isn’t a redness halo around the sac; just a red sac. There seemed to be a finite amount of blood around the sac, presumably from scratching.

To me, it doesn’t necessarily look like a flea bite; however, it is quite coincidental that I did find a few fleas not that long ago. Any input would be appreciated.

Maybe if it’s infected? In my experience flea bites are little red circles, but a few sites on google say that an infected flea bite might develop into a fluid filled blister instead.

I doubt it. It could be any insect bite, or a random skin growth. You could send those pictures to your vet and ask him/her. That’s probably the best way to get accurate information and head off your freak outs.
