Cooper did great last night. We put him in his crate at 9pm~ish right next to Parker's mattress and we never heard a peep from him. I went in and woke him up around 6:30 this morning to take him out. He will grab just about anything in his mouth, so we have to keep him contained. For the past hour or so he's been loose in the kitchen with me. He's been playing with toys and getting petted. He just laid down and is taking a nap. He loves to see what is going on around him. He has no problem with our stairs at all. In fact, he climbed up on a chair and then our table this morning and jumped over my baricade a few minutes ago. We will gradually introduce him to different spaces in our house.
Still no barking or wimpering, but he has 'marked' inside a few times. I am glad I bought that enzyme cleaner stuff yesterday. It's been raining since we got him and he's been good about getting wiped off when we come inside. He is a very nice dog! He was a stray and it makes me sad to think that someone lost him or abandoned him. He's very happy, loving, and well behaved. I think he fits in with our family well!
