“A canine’s penis has a bone in it, and in the midst of the bone there’s a gland inside it that swells up when the male’s copulating,” Dr. Wardany explains. “The aim is to maintain the penis inside the feminine.”
As soon as that occurs, the canine are caught collectively for a brief time period till the swelling goes down. That is sometimes called a male canine “tying” a feminine.

You shouldn’t see this discharge all that always and solely in small quantities.
Nevertheless, if you’re seeing a whole lot of discharge and it’s accompanied by your canine licking his privates excessively, it could point out a critical well being downside akin to a urinary tract an infection or canine cancer.

My sister’s household has acquired to expertise this on a number of events, a lot to my utter mortification.
So, why do canine do that?

Canine smelling and licking one another’s non-public areas is completely regular dog-on-dog interplay; nonetheless, there’s at all times one or two canine that seemingly go overboard and gained’t put their noses or tongues away. This could result in uncomfortable conditions between pet mother and father, some who won’t perceive what’s going on.
