My dog has a sudden, movable lump on her back. Should I be worried?

Pet's info: Dog | Great Dane | Female | spayed | 108 lbs

My Great Dane just got a lump/bump right on top of her back on her spine. It can move around when I push on it/touch it. It seemed to just appear one day out of nowhere. Any ideas ?

These skin lumps can arise from a few different causes and they are usually not a big concern. The first thing I would check is if Juna has had any vaccines or injections lately. These are often give in the back near the shoulder blades and can sometimes swell a bit. They also sometimes get these from bites or other trauma. In these cases, the lump is just some fluid buildup under the skin. These usually start going down within a couple of weeks. Other causes can be from a blocked gland, fly warble, abscess or a tumor. You can safely wait a week or two to see if it goes away on its own. If it continues to grow of doesn't go down, then it's best to take her into the vet to get it checked out.
