Just started marking in house
We have a rescued male GSD that we adopted from the pound at 18 months. He is now 5 years. Cody is a highly intelligent dog. He does have a doggie sister.
Just recently Cody started marking inside the house. It only happens if we are home, but in the back of the house. We have a baby gate as Cody has started to get into the trash in the bathroom. We close those doors. Normally our dogs are with us. If we are not home, they are in the house and we have pet sitters.
Cody does not have a UTI, so my second guess in behavioral. Again, if we are present, it does not happen. We are a rottie family and this is our first GSD.
Cody is also very sensitive and the approach must be positive. We immediately take him out after the incident.
Does anyone have any suggestions on this?
Thank you for your time.
