The world is set up in these times for people to keep their dogs inside most of the time but mostly if someone spends so much for their dogs and all the care and love for thier dog then it stays important to keep their collie protected from elements, theft, bugs, dirt, escape, and from bothering neighbors.  I expect you to keep your collie inside at night and most of the day. I do not check on you or stalk your home.

Now a days, especially if you live in a neighborhood you should keep your dog or collie inside most of the time anyway. It is even required in some neighborhoods if you are away from home or sleeping at night. It really works out great.

You will find that a collie house trains easy very young, will stay cleaner, healthier, and less chance of digging in gardens, bothering neighbors, or running off with other animals.

If you leave your dog or collie outside too long they often will begin a habit of barking. They can hear well and will hear plenty of things far off to bark at.

It is unfair to others to keep dogs outside to hear barking while you are gone or while you manage to sleep through it in the night. Collies are happy inside and it is not difficult to let them in after they finish their outing. I used to think they needed to stay outside longer but they can run fast in circles in the yard for enough exercise to get done quickly.
