We staked out the perimeter to build our "dog park" last weekend. It will be about 1 1/2 acres of woods/creek/ravine to run in.!
Its going to be quite the project to fence the hills, but so worth. The dogs really love to just "lay it out!"
I cant wait!! Wildo..I will be considering bartering DVDS for dog park usage..lol!!
But, in answer to your question of letting him run loose, I wouldn't risk it. He still seems a bit impulsive. I think girl dogs are more clingy than males, too.
