Why does my dog have musky urine and milky penis discharge? Infection?

Updated On September 23rd, 2025

I have a male cocker spaniel, 3 years old. The past 2 days I've noticed a very strong musky smell to his urine. No trouble urinating, no blood in the urine or visible discomfort urinating. He's eating and drinking fine and no change to his energy. He went to the groomer's on Thursday for a bath/cut and they expressed his anal glands. The smell is from the penis/urine, not his anal glands. Today I saw a drop of milky discharge from the penis. Could it be an infection? Or irritation from the bath?

The strong smell to his urine can be an indication of a UTI, and oftentimes there is blood in the urine but it is not visible to the naked eye, only under the microscope. I would have him seen by a vet first thing in the morning. The vet can do a physical exam, blood tests, and urinalysis to diagnose if he does have a UTI, and can prescribe medications for it as needed.
