Re: My dog is playing with my painting materials!
We used to have to keep a dog in a crate. We called it his "house". It had comfortable blankets for him, enough room for him to turn around. He would use it for a den when he wanted to feel secure and would go lay inside even with the door open. Whenever we needed him to go inside we would tell him "go to your house" and he would run to get in. Then we would give him a couple of saltine crackers, or a small dog treat and he would lay down and eat them while we closed the door.
They say you're only depriving them of about ten minutes of running around free, then they just go curl up somewhere and sleep anyway. If you make it a chance for reward and never use it as a punishment, they view it as a safe place to be, their place.
