Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Unfortunately, it is very hard to say what the lump is without full clinical examination. I suspect it could be a cyst, hematoma or a skin mass. Please, take Frankie to your regular vets for an appointment after the weekend. Your vet may want to do a needle aspiration of the lump (so sticking a needle into the lump) to make the final diagnosis and recommend adequate treatment.
