Noticed small lump under skin on right rear side in front of thigh. Tonight, there's another one twice the size of the other on right side mid-body. No response to pain when pressed. No lethargy, vomiting, problems urinating/defecating, no loss of appetite. Female unspayed shih tzu 16mo old. Has given birth first 2 heat cycles. Vet closed tomorrow. How urgent is this?

They aren't urgent, but these lumps do need to be checked out by a vet, as any suspicious lumps should be examined. They could be cysts, abscess, or benign tumors. The vet can perform a test called a fine needle aspirate on it. To do this, the vet sticks a small needle into the lump to get a sample of it's cells, and examines the cells on a slide under a microscope. It's usually painless to the animal, and relatively quick to perform. I would have Princess seen by a vet tomorrow to have these lumps examined and diagnosed so they can be treated as needed.
