A lump on the neck could be an enlarged lymph node, abscess or gland (thyroid). If your pet is weak, a veterinary visit ASAP is recommended. Small animals typically do not have much stored energy reserves, and by the time they appear sick, they have been ill for a period of time. Some of these conditions might respond well to treatments (infection) versus neoplasia, which can be treated but with difficulty.
