i'm sorry Mika has mammary gland tumors (MGT). We actually did surgery on a chihuahua two days ago with this problem. the surgeon removed the tumors and sent them out to be biopsied, and he also spayed her at the same time. the Chi was 10 years old and did great.
I think Mika should have the surgery. It is completely necessary so the tumors can be analyzed to see if she has the dreaded C... a fine needle aspirate cannot tell you for sure if it is or isn't.
Good Luck! I'm sure she'll do just fine!
