Hi! This is Sweetie, my collie mix! She’s about 15 years old but still gets around great and has energy like a puppy! She recently got this gland/mole looking spot on her upper back side. It doesn’t seem to hurt her and doesn’t mind it being touched. However it gets nasty gunk in it (as pictured) and within a day of me cleaning it all off, it is back again and has a bad odor to it. Any idea what it is or what to do about it?
