Hi, our dog is 11 y.9., mixed breed pittie, has developed a big hump between her shoulder blades. It's hard to the touch but when I bear down on it, she does not react, so it is not painful. She is eating and drinking. No vomiting or diarhea, no fever to the touch. We are in SE Arizona.

However, she is walking very slowly and acts sleepy. The hump has appeared literally over the last couple of hours; the dog has been indoors, did not bump into anything.

Google offers all kinds of scenarios, but has anyone had this happen? Thank you.
