The Collies play all day. The 3 month old has found a way out of the fence one time. She did not go anywhere because her cohort could not get out. She stayed next to the fence by Sawyer. Neighbor spotted her and put her back in the fenced yard. I hope in the next month her size will prevent any possibility of this reoccurring. I went around the fence and blocked any possible escape route I could find.
Most of the time when I go somewhere they go with me in the truck. A quick run to the store was the exception. I don't crate they have a dog door where they can go in and out of the house when they wish. They know when they need to potty not I.
