What causes urine marking?
The most likely cause of urine marking or urine spraying is to assert dominance.
Your Labrador may be marking in the house because he feels the need to take on an alpha role – Urine marking is a way to stake out his territory and assert his dominance within his pack. He could also be asserting his dominance over potential intruders.
If you aren’t taking the role of the Alpha dog, your Labrador puppy will start taking on that role at the age of about 8 months or so when they start becoming aware of the hierarchy.
In some cases, Labradors will even pee on their owners beds. This is because the bed is the safest and most important place. Thus, if they mark that, they don’t need to mark the entire territory.
