For a few months, I've noticed a giant black spot over the side of my 9 month, female, spayed corgi. Then it seems like a few more spots appeared. They look like bruises to me.
A few days ago I noticed a few more spots appeared. I also noticed a black area under her tail, by her butt. I'm now getting worried that it might be something serious.
Does anyone have any clues what's going on with her?
