my parents have two shist tzu (sp?) who mark inside and outside. They are 2 years old and spayed. Slowly my parents have been replacing the carpet with hard wood because it seems like they prefer to mark on the carpet when inside. I have two boys, a boxer, and 7 month yorkie who only mark outside. Even when my boys are at my parents house they will sniff the spots that are marked by my parents dogs , but still would never go in the house. |
