Ummmh, this is a very "active way" to walk a dog.

"...พ่อปั่นแม่ซ้อนท้ายแล้วให้โก้วิ่งตาม..."

Somehow, (I think) the original aim of walking the dog is "to establish bonding (communication) between man and dog" and to get benefits of physical exercises.

With a 'proper' leash, a dog learns to 'walk with' us -- sensing and anticipating our direction, speed and 'mood'.

Through a leash, we learn to see the dogs' world -- their interests, their body language, their mood (fear, fun and who's boss).

It may be fun to prove that 'most' dogs speak the same language - no matter what their breed; no matter their owner's breed ;-)
