Urine Marking in Dogs

Dogs mark with urine to tell other dogs where their territory is.

Urine marking is a common behavior in dogs, especially males. By depositing urine on different surfaces, a dog leaves scent markers that communicate to other dogs. Urine marking is mostly a way for dogs to mark their territory.

Urine Marking Is Communication for Dogs

When you are out taking a walk and your dog is sniffing around everywhere and leaving small amounts of urine on various surfaces, he is communicating with dogs that have already urinated in those spots and those that will come later to sniff around.

It turns out that dogs can glean a wealth of information from sniffing the urine of other dogs. They can probably discern each other's sex, health status, and even mood.

Territorial Marking Is Most Common in Intact (Un-neutered) Male Dogs

We've all seen a male dog lifting his leg up to urinate on something. This commonly begins around 6-8 months of age in male dogs, when they hit puberty. If a dog is neutered before he begins lifting his leg to mark things, the behavior may never develop. If he's neutered after he begins lifting his leg, the surgery may end the behavior, but not always.

Some dominant female dogs will also lift their legs to mark territory, but it's not terribly common. Still, un-spayed female dogs urine mark by squatting much more frequently than spayed females do. They are leaving information about where they are in their estrus cycle: they're advertising to neighborhood male dogs.

Note: dogs also use feces and scratching at the ground to communicate information about territory to other dogs.

 

 

What to Do When Dogs Mark Inside the House

When dogs mark their territory outside, it's not usually much of a problem for the owner. However, some dogs urine mark inside, and then something must be done. Here's what to do if your dog is urinating in the house:
