Love the video. The simplest thing make dogs happy, and they are very happy dogs to have all that room to run! When they came at you the first time I thought, "watch the knees" Niko used to barrel into me, take me if I wasn't paying attention!
My mom has a little Italian Greyhound.. shes fearless! She'll shamelessly run up to any dog to instigate a chase! Its her absolute FAVORITE game ever.. zooming around racing other dogs. Shes just so darn fast. I'll rent her out to you guys for a nominal fee hehe
