My Morkie has mammary tumors. Is surgery safe? Should I spay her?

Updated On September 23rd, 2025

Pet's info: Dog | Yorkshire Terrier | Female | unspayed | 11 years and 10 months old | 4 lbs

My 12 yr old 4 lb Morkie has 2 mammory rumors at the lower half of her breasts and they are hard. She is still intact. What’s the life expectancy once the tumors are removed? Should I get her spade during the surgery? Do you think she’s too little to go through all that? She is nit sick and acts her normal self. She has begun to loose her hair asymmetricaly. I had blood work done to check her thyroids per the vet. They are also going to test her urine.

Mia's life expectancy after the tumor removal depends on if the tumors are benign or malignant, and if the cancer has spread should they be malignant. If the cancer has spread, the extent of the spread determines the outcome. I think having her spayed is a good idea, as she will still be prone to developing a pyometra with her uterus left. A pyometra is an infection of the uterus that is fatal without treatment, and that would require another emergency surgery to fix should she get one. No, she's not too little to get this surgery, and I strongly recommend it. Best of luck.
