Hello. I am new to this site. Last night, I noticed a circular red spot on the belly of my 7-month old male boxer, near one of his back legs. The spot was about 3/4 inch in diameter and was not open or wet, just looked like a big blood blister almost. Now tonight, about 24 hours later, he has about a dozen of these red spots--none wet, all located around his lower belly, but they don't seem to be sensitive. And I noticed a tick that was attached to his belly. I removed the tick--I would guess it had been there for a decent amount of time because it was dug in pretty good. Any ideas on what I should do? We live in Minnesota and he spends a good deal of time outdoors. Any help would be appreciated. Thanks.
