I'm at a friends house. She has a small dog that has a large lump on her neck. She left the dog with a babysitter for about four days so this lump came over that period. The lump is very hard and I can't move it around. It doesn't seem to be as painful as it was a couple days ago but she still needs help. Its very large and I'm unable to move it around. Please help me ASAP
Thank you
Kaylee
