Urine marking conveys information to other dogs about territory, social status, etc.
Hormones cause unneutered/unspayed dogs to mark more frequently.
Marking can arise with moves, new people, pets, furniture to claim space.
Some dogs mark over the urine of companion dogs.
Dogs may mark when stressed or anxious to self-soothe.
Use baby gates to restrict access to favorite marking spots.
Eliminate urine odors with enzyme cleaners so dogs aren’t drawn back.
