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!
