Junior has had this lump on his left front leg, at first I thought it was maybe from them playing rough since the boston's are good at that. He's had it for awhile now and it feels kinda hard. His leg is white and it looks like a bruise kinda and he always licks and bites at it. Any idea's what it might be? Iam taking him to the vet on friday at 10:30am to have it looked at. I was thinking maybe its a cyst or something. Its under the skin so looks red/brownish and funny color due to him licking it.
