I don't see any photos attached to this post so I am not able to see the lump. If the lump is getting bigger than you should have him examined by a vet to determine the cause. Your vet can do a needle aspirate to help diagnose and then your vet can recommend a treatment plan. He may need an antibiotic, anti-inflammatory, or your vet may want to remove the lump.

    Hello and welcome to Petco Pet Education Center, formerly Petcoach. This lump needs to be checked and analysed as there are many conditions and types of tumors that could look like that. take Jed to the vet, they will perform a fine needle aspiration on the growth and send it to the lab for analysis. when the result comes, the vet will advise what needs to be done according to the diagnosis.
