Hi, we have a 1 yr old mixed breed female dog that has a blister on her axilla. Does this look like something serious or something we can clean and treat with neosporin? I would like to add ahe does have a history of demodectic mange as a puppy, but recovered well with treatment. Thank you

That could be a growth, from an insect bite, or from an infection. In order for it to be treated properly, it needs to be diagnosed, which I cannot do from a picture. I would have Esme seen by a vet to have this diagnosed and treated.
