Ahhh see my staffy that had the 2 C lumps, Hers was aggrovating her, She kept trying to itch them and rub them.
Just see what the vet says and keep an eye on the growth of the lump.

Is the lump under her neck or on the top of her neck? coz my daughter nearly had heart attack a few weeks back when she felt a lump on her staffy dogs neck underneith at the side ..when i felt the other side there was one the same, It was his glands lol.
