Blood-filled bump/blister on lip?
My dog's 20 months old, generally healthy, no issues lately.
Yesterday I noticed a bright red (blood filled?) bump on her lip, and it's still there today and seems to be larger. I've also noticed blood on the ball I was throwing around in the park half an hour ago. The bump seems to be bleeding. I don't think this is a spot she could have easily bit herself on.
Can anyone suggest what this might be? I'll be going in to the vet for the annual rabies vaccine next Friday (a week from now) - would you suggest going in earlier to have this looked at?
Any advice would be great. Thanks in advance!
