Dexter doesn't have much of a chewing instinct. He does have that bite and rip/ shake instinct down though. We were playing tug of war last night with his rope toy. Once he started to tire, I let him have control of the toy. He went to shake the rope and smacked himself in the forehead with the knotted end that wasn't in his mouth. I got the "wtf, man?" look, he dropped the rope, and walked out of the living room to go lay down in my bed. It was sad and adorable at the same time.
This story is related to the #longbone above. I wish I could find more toys for him to play with. The only things he shows interest in the majority of the time are bully sticks and stuffed animals.
He has stopped the car-peeing for now. I purchased a different enzyme based cleaner than what I was using and I think that got rid of his previous pee smells. He seems to be enjoying car rides more now, as well. I think he's stopped associating them with being left at the shelter and now thinks of them as what happens before he gets to go play with his friend.
