My dog is a mix Maltese and shitzu breed. 13 years old. She recently developed a large red lump on her abdomen (under her nipple) area. It was only a red lump at first but after a day it was filled with fluids. What is it? What should I do? And how much would the treatment be around? Thank you.

It looks like she could have an infection and/or a mass so she should be examined by a vet for treatment. She might need an antibiotic or it may need to be removed. The cost really depends on the vet and the exact treatment plan. If she just needs an antibiotic to treat an infection then it shouldn't cost more than $100 for the examination and antibiotic.
