Updated on September 23rd, 2025

Pet's info: Dog | Dachshund | Male | neutered | 22 lbs

My dash hound dog has a lump first appeared to be a nipple looking then it look like a skin tag that swelled to size of small. green grape. Over aprox. 6 months time Skin color and didn't seem to bother him, somehow it were open and he keeps licking it won't leave it alone and it stinks ? I cut the hair away from it today and put peroxide on it and then Neosporin and bandaged it . Is there something else maybe I need to know or do

It sounds as though this lump bothers Avery quite a bit since he keeps licking it. The lump could be caused by a benign or malignant mass, cyst, etc. and may have become infected due to Avery's licking. At this point, there isn't anything that you can do at home. A vet should examine Avery and will likely need to perform a fine needle aspirate (using a needle to draw out a few cells from the mass - it's quick and relatively painless!) so that the sample can be examined microscopically. From there, Avery may need oral antibiotics to treat any infection. Until you can take him to the vet, put an e-collar (cone) on him to prevent further licking and irritation of the lump. Try to avoid putting any additional hydrogen peroxide on the lump, as repeated use can delay healing. I hope that he's on the mend soon!
