My girl is a 16 years old Cheweenie (chihuahua and dachshund mix). Last month the vet found a small mass on her spleen. She has some arthritis and get’s monthly Librela injections, also have some heart issues, but they said is minor and no need of medication, just have to monitor it. Her sight is starting to fade, but overall she’s in a good shape, enjoys little slow walkies and have tremendous appetite. We have an appointment next week to discuss the option of a surgery. I’m just worried if she’s going to survive the surgery and heal. What can I expect if we don’t get the spleen removed? Should I insist to get the surgery or not? Please share some insights.
