Is it a lump or is it her dewlap? It's definitely not just fur.

I'm not sure , but my dad said it's getting bigger

A dewlap would generally be even across the front and under the chin. It will just feel fleshy. If it's a lump off to one side and is hard or firm, it could be an abscess. Abscesses under the jaw are commonly associated with an infected tooth. Other possibilities would be tumor or cyst. So if it's not her dewlap, she needs to be examined by your vet. If it's a dental abscess and it's left untreated, it can spread to the bone, and it's not a good prognosis after that.
