Please don't attack me. I love my dogs. We don't own where we live and putting up a fence isn't an option. From the time we got him he was always on a leash to potty. When he proved that he would stick right with us, he was allowed to go out without a leash. When he showed us that he would potty and play in the yard with the other dog, we allowed him to do so. He had been excellent about staying in our yard and the surrounding property (farm fields belonging to my landlord) and coming right back home. When he strayed too far, he would return immediately if we called his name. When we'll be gone for a short time he is kept in his crate in the house - when it will be longer, we tie him out (even though he absolutely hates it). We do try to watch out for our pets, even if you don't think so. I'm sorry that my post upset you.
snowydiamonds... I'm sorry, but only allowing him out to potty and then make him stay inside would make him absolutely miserable.
