Hallway speed bump

"Harvey, a 5-year-old red Golden Retriever, had a hard time walking down the hallway because another Golden, Jacques, was laying down taking up most of the hallway. Even with human 'coaching' he just couldn’t do it, yet Lily, a 6-month-old Cream Golden, was up to the challenge and showed him how to walk over the speed bump. Harvey was still not convinced."
