I needed this last week!
While my parents were away in Mexico, I was walking their dog — Pete — four times a day.
With this ingenious device I could have stayed on the internet and indoors even longer.
I think I’ll get one for all my dog owning friends for Christmas!

Cesar Millan (aka Dog Whisperer) touts this as a necessary tool for energetic dogs…it is definitely on my to do list ….. right now, Oliver gets 3 or 4 walks a day….and still has too much energy!
