It doesn't look like a tick bite to me, aniech22. In our dogs, at least, a tick bite is pinker, more like a smooth lump, and drier than what I can see in your pics. So likely it's some sort of localized infection. If it's changed (developed pus) or you see more of them, you might want to at least call your vet clinic and see if another visit is in order.
And welcome to the board, btw!
