Hi There. My coonhound (3 y/0) seems to have developed a purplish mound recently next to one of her teets. She licks at it a little, but it doesn't seem sensitive to the touch. She's acting normally and went for a good run this morning. Any idea what this is? Because she's acting alright, this doesn't seem to be an emergency so we can wait until Tuesday to go to the vet. However, I'd be interested to see if you think that is ill-advised.
Thanks for any help.
