Bad picture sorry...
Its dry and crusty like and its getting a little bigger. I had it looked at when we went to the vet the Wednesday before last. he said he wasn't sure what it was but to watch it.. I noticed it the Friday before we took her in for her shots.
She also has a small rock like lump on her right side by her shoulder (kinda where they gave one of her shots) I'm not sure what it is and she also has a small pea size lump about 3 inches from her neck on her chest.
I am thinking the larger size lump is from the shot??
I have to wait an hour before I can call the vet they are out to lunch right now...
