Right on the top of his head closer to his right ear.
Size: I have not messured it but it looks like a good 3in wide and an 1in high
color is hard to say he is a white boxer with some brown spots, It looks like a dark brown to black (maybe its blood)
the bump has been their for a while it was the size of a penny then it would go away.
When it came back I thought he had hit himself and was waiting for it to go down like the last time. This time the bump just got bigger. But like I said he is acting normal without pain. Hope this helps I can email a picture if it helps
4 weeks ago. Yes he had it las year but very small, then it would go away. Could it be a bite from a spider?
4 weeks ago but not that size it was small, just about 4 to 5 days ago did it get this big. and just yesterday it started to bleed or discharge something.
