Do you have a yard that isn't fenced? Here's an easy way to build a temporary fence fast and cheap. Many buildings will let you have their pallets. If you own a large dog make the pallet fence 2 pallets high so they can't jump out. Do your whole yard or just do an area for your dog to run in. Unfenced yards are a big hazard to your dog, they can get loose and become hit by a car, they can be stolen easily, and they can be hurt easily by people walking by.
