So, I got Bella cut much shorter on her body this past trip to the groomer and now I've noticed a quarter size lump on her back - on the right side closer to her butt than her shoulder. You can't really see it visibly unless you were really close and looking for it, but you can feel it when you pet her. It's not round- it's an odd shape and somewhat flat- sort of feels like the skin there is thicker. It doesn't move and doesn't seem like it is causing her any pain or discomfort. She is running about and healthy, but I'm still really concerned. I made an appointment for the vet for Friday morning to have her checked out. I don't know if it could be scar tissue from some early incident? or could it be a tumor? I really hope it isn't serious. I am not aware of any trauma to that area. I did a seach of older threads and it seems like people have found lumps after shots. I have had Bella since April and she got up to date on shots from the rescue back in April. Actually- she did get a steroid shot in her back in late July when the emergency vet thought incorrectly that she had degenerative disk disease... could that be why she has a thickening of her skin? I don't even know if that's the spot where she got the injection. Would it be hard and not moving like that? Would it still be there over a month later?

Anyone have any ideas for me?
