My 2 year and 4 month old female doberman has this lump on her neck that has grown rather quickly. She had a fine needle aspiration done at her vet. Results show not cancerous. I was told to monitor it but they recommended it be removed if it is growing quickly. Anyone else have this issue with their dobie? She's had this lump for almost 2 weeks. She has had several other lumps in same area but those seem to have disappeared.
