Why is my dog's penis oozing yellow discharge and he's vomiting?

Without pictures it is difficult to say what this is for sure. This could be smegma, which is the normal yellow discharge that is seen coming from a male dog's prepuce, which is a natural lubricant for the penis inside the prepuce. If it is not liquid at the prepuce you are seeing and a pustule, this could be infectious. If you could provide photos and post again it may help determine what this is exactly. Otherwise, a veterinarian should take a look at this so that the most appropriate diagnostic and treatment recommendations can be made. I hope this helps! Please let me know if you have any other questions or concerns and I would be more than happy to help you further.

Yes, it's normal to see a small amount of yellow-green discharge at the tip of the penis in male dogs - this is called smegma, and is comprised of oils and secretions from inside the prepuce (the skin sheath that surrounds the penis). As long as Chester is acting normal, this shouldn't be any cause for concern. If he is licking this area excessively or having any trouble urinating, then I would recommend having it checked by your vet as these can be signs of an infection.

Thanks for using Petco Pet Education Center, formerly Petcoach! Without seeing Harvey it is hard to say for sure what is going on. There is a normal yellow/green mucoid discharge (called smegma) that male dogs have to coat the penis inside the prepuce. There could also be an infection, like a bladder infection, but typically they have signs of increased thirst, frequent urination, and producing small amounts of urine at a time. To be sure, I recommend taking him to a vet for an exam and they can check the urine. If he isn't showing the other signs, I am suspicious this is the normal discharge male dogs have. I hope this helps. Kisses to Harvey!

Hello. Xavier has Balanoposthitis, an inflammation of the glans penis & prepuce with excessive preputual discharge. Mild cases are generally clinically insignificant, but if severe, treatment may be needed. Have Xavier evaluated by your veterinarian to make sure there are no lesions on the penis. A mild saline flush may be all that is needed, but it is good to just check things out just to make sure all is OK. Thanks for using Petco Pet Education Center, formerly Petcoach.

A certain amount of discharge, especially in intact male dogs, may be normal. This discharge is known as smegma. If there is an increased amount or if you notice a foul odor, excessive licking and difficulty urinating, then it may be that he has an infection either in the [urinary tract](https://www.petcoach.co/dog/condition/utis-in-dogs) or under the prepuce. Take him to your regular vet when they open for an examination and diagnosis. They will be able to provide appropriate pain relief and treatment.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! The elevated sodium likely has nothing to do with the discharge. The increased sodium while he was sick was likely due to dehydration. It is normal to have a small amount of discharge from the penis in male dogs. Excessive amounts that cause licking or urinary signs is NOT normal and can indicate a prepuce infection or a urinary tract infection. Use mild soap and water to wash the discharge away and see if you can retract the prepuce to see if there is a lot of discharge on his penis. If you see his penis coated in the the discharge that is too much and he should see your Vet. If you do not see any or very little he is likely fine. Good luck!

I would have your dog checked for a urinary tract infection. These types of infection can cause a change in the color and consistency of the urine. It is normal for male, intact dogs to have some discharge from the prepuce but if the urine itself is abnormal he needs to be evaluated by your vet and have his urine checked.
