Normal can be quite difficult to define as it varies considerably from dog to dog. Does his sheath look inflamed at all ? Does his penis itself appear inflamed ?
I'll type out what it says in the book anyway.
A male dog normally produces a cream yellow lubricant (smegma) in the sheath of his penis. In young dogs this fluid can be quite productive, dripping out from the prepuce when the dog is resting.This preputial drip can be aesthetically unpleasant but it is not a medical problem.
An inflamed penis and prepuce is a sign of balanoposthitis infection. The preputial drip is excessive and foul smelling and the dog increasingly licks the tip of the penis. There are many potential causes of balanoposthitis including a bacterial or herpes virus infection, a foreign body such as a grass seed or a physical injury, or even a failure to secrete sufficient lubricant.
Bacterial infection can be cultured and antibiotic sensitivity determined. Viral infection is much more difficult to diagnose. Failure to respond to antibiotics could indicate a herpes virus infection which could be transmitted to the female during mating.
Excess smegma and foreign bodies such as plant seeds are flushed from the sheath with warm saline or dilute chlorhexidine antiseptic. Preputial flushing also reduces the quantity of normal preputial discharge.
So firstly when you wipe it give it a sniff, if it doesn't stink it sounds harmless and normal to me.
