I am so sorry, but there is nothing you can do at home for this, other than try to keep it clean if it breaks open and bleeds (which it looks like it could do at any time). Short of taking her in, there really just aren’t any options... this would require surgical removal. If she’s comfortable, eating, and happy, it’s not wrong to just love on her for the time she has left and not pursue treating the tumor. Again, I’m sorry I don’t have more options to offer you. Thank you for asking Petco Pet Education Center, formerly Petcoach.
