What's this growing, hairless lump on my dog that leaks clear fluid?

Pet's info: Dog | Pit Bull Terrier | Female | spayed | 6 years and 1 month old | 85 lbs

Just wondering what this may be it’s been there about a year and has got bigger and hairless. If slightly squeezed clear liquid comes out of pores. It doesn’t seem to bother Marley. Thanks I would appreciate the feedback.

Based on the picture it looks like Marley has a small cyst. Cyst will fill out with clear fluid but can also have different color fluid. Cyst are typically non cancerous and nothing to be concerned about. However you should never decide what a mass is based only on looks. Some cancerous masses can look like anything for example mast cells tumors. I would recommend taking Marley to a vet for an aspirate of the mass. The vet can look at the cells under a microscope and tell you what the cause it and if it should be surgically removed. hope that helps
