My dog has a small bump under his jaw it’s hard but he doesn’t seem to be in any pain. I’m thinking it could be a mosquito bite because there is a lot in the are where I live. He is acting normal running eating drinking water everything like normal except for the bump what could it be?

It could be from an insect bite, but it could also be from an injury or a growth of some sorts. Keep an eye on it for now, and if it gets bigger, starts to bother Peques, and/or doesn't go down in the next couple of days, I'd have him seen by a vet. Best of luck.
