Putting to rest previous assumptions that overmarking is done exclusively by males to hide female urine marking, this study reveals both male and female dogs do it. And they do it to urine marks of either sex, not just marks left by the opposite sex.

How do you stop a male dog from marking in the house?

Spay (or neuter) first

Spay or neuter your dog as soon as possible. The longer a dog goes before being spayed or neutered, the more difficult it will be to train them not to mark in the house. Spaying or neutering your dog should reduce urine-marking and may stop it altogether.

Why is my dog peeing on me all of a sudden?

Dogs will pee on a person suddenly due to excitement, fear, illness, territorial marking, as an accident, or due to not being spayed or neutered. It can be stopped though, particularly if due to a behavioural issue. If you want to know more details about why a dog would urinate on a person, read on.
