Why does my dog have sudden red spots with black dots like bites?
Updated On September 23rd, 2025
My two dogs have little red round spots on them. Looks like it could have a small black dot in the middle like they were bit. They almost look like blood spots. They look like they could be getting worse on one of the dogs, bigger around. These just occurred in the last few hours

It is hard to tell for sure it if both dogs have it I would be most suspicious of black fly bites, which are often just a local irritant. However, the other big concern would be petechia hemorrhages- which could come secondary to things like rat poison exposure! If they are feeling fine and were exposed to flies recently this is more likely but if they seem to feel off or had any other signs of concern it would be safer to take them in!

It does look like fly bites. If he isn't scratching or licking, then I think it is safe to just monitor. If they spread, seem to bother Duke, or if new areas show up, then I would have him checked out by a vet. The sudden onset is unlikely to be caused by something else, but these lesions can also appear with several different clotting disorders and it is always better to have it checked out by a vet.
