Is it normal for my dog to have white or yellow liquid from his penis?

Updated on September 23rd, 2025

Hi, I’ve noticed that my dog has some white/yellow liquid coming out the end of his penis, only a small amount every now and then. Is this normal? He also had high sodium levels in his blood recently (although the had been sick the day before) so not sure if it’s linked.

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!

What should I do about yellow discharge from my 8-week-old puppy?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Some discharge from the penis can be normal. I would use a mild soap and water to clean the area 2-3 times per day. When you have him in for his next vaccinations with your Vet have them look to make sure it isn't a bigger deal requiring antibiotics and prepuce flushing. Good luck!

Is yellow discharge from my male dog's penis normal? Should I worry?

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.

Is yellow discharge from my young neutered dog's penis normal?

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!

What's the discharge on my unneutered male dog's penis? Is it normal?

Thanks for using Petco Pet Education Center, formerly Petcoach! The discharge you are seeing is a normal substance that unneutered males produce to lubricate the penis. Sometimes the discharge comes out of the prepuce. The production of this substance is decreased when pets are neutered. You can continue to wipe it off it noted but no treatment is needed. Kisses to Simba!

Is milky yellow liquid on my male puppy's penis after pee normal?

This is normal. As long as he’s urinating normally, acting normal, eating and drinking, no vomiting or diarrhea, there is no reason for concern. The amount will increase some as he gets older, then decrease following surgery to neuter him. Thanks for asking Petco Pet Education Center, formerly Petcoach!

Why is my dog's penis discharging white fluid and wetting the bed?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Are you sure that the bed isn't wet form him licking his penis? If he has an infection of his prepuce or penis he may lick a lot. I would have a Vet examine the skin of the prepuce and see if there is an infection. We treat with antibiotics and prepuce flushing. I hope this helps and I wish Mars the best!

Is white discharge from my male dog's penis normal or concerning?

It is normal for male dogs to have a small amount of discharge from the penis. Some dogs do a better job then others in cleaning themselves. It is usually a whitish to yellowish substance. If it is just being noticed occasionally I wouldn’t be concerned, however if it is enough that he is leaving puddles on the floor then he should be evaluated by a veterinarian. Best of luck and thank you for using Pet Coach.
