I tried putting this on the pets board first, but I can't make the PIP work over there, so any advice would be appreciated!
I just noticed my dog has a rash looking thing on her back armpit. She's four years old and has never had this before, so I'm not sure if it's an allergy or injury. Part of it is little red bumps, and part of it looks like a cut. On Saturday she bolted after a squirrel while I was walking her, and ran through a lot of brush into a ditch. She may have come into contact with a plant she doesn't normally encounter, or she may have cut herself in all of the bushes and weeds, or it could be from something totally unrelated. She is not scratching at it, but she is licking it. Other than that, she is acting completely normal and is in a good mood.
Does anyone have any idea what this is? Do you think I should I take her to the vet today, or just put something on it and see if it gets better first?
