Male Dog Penis And Sheath Discharge

The phone call started in an ordinary way, “Dr. Randolph, I need to make an appointment for Gus.”

A quick glance at Gus’ file in our computer system showed he wasn’t due for a routine visit, so I inquired of his owner about possible problems as a reason for the visit.

“He has a yellow-green discharge from his penis.”

A yellowish to greenish small-volume discharge from a male dog’s sheath is normal.

I closed the appointment book, and pressed F1 on the keyboard, sending the computer software back to the Main Menu.

“No appointment needed,” I explained to Gus’ master. All male dogs have a yellow-green discharge. It’s actually coming from the sheath, not the penis. Quantity can vary from undetectable to a drop, but it’s all normal.”

The material, which looks much like pus to the naked eye, is actually made of cells and lubricant fluid in the prepuce that surrounds the penis inside its protective sheath. It has a pungent, acrid smell and will sometimes be noticed where a male dog has lain.

Discharges from the sheath with other characteristics, such as blood, or a large volume of material that resembles pus, would be a cause for concern.

As for me, I’ll just have to wait for a big, sloppy Gus-kiss until another day.

See you tomorrow, Dr. Randolph.

  1. My dog is excessively licking his private area and it only bothers him when he is standing up and when he sits down he doesn’t whine when he urinates

  2. My 5 year old dog is not neutered and he has recently been aggressively licking his penis and then when he gets up there’s a little wet spot (clear and odorless) on the floor – nothing appears swollen or wounded. Is this normal?

  3. My dog’s a rescued dog, and not spayed yet, ( it’ll heppen next month) is this kind of discharge gonna stop after the surgery?

  4. My pup I rescued got neutered and fo The past 2 months he’s been having discharge and been licking himself like crazy? He’s going on 18 months? Is this normal?
