My pit bull has a hard lump under her left side rib cage. I'm curious if it's an organ or something concerning.
It is difficult to assess what it could be without examining your dog.
It could be small pustules provoked by something that has caused her allergy, small abscesses or even tumors. Most abscesses get broken when they reach a certain size.
If your dog acts normally and has no problem eating and drinking, it doesn't seem to be urgent. Follow the growth of the lump and if it starts growing, if you notice that it is causing pain, or if it doesn't disappear in approx. one week, you should take her to your veterinarian to examine the lump and determine the cause.
If you want to be sure it is not something harmful, take her to a vet, so they can determine better what lump is.
All the best for you and Blu.
