Glad to hear he is doing better on the new food. I was wondering how he was doing. We do the same with Spiel. When he gets too wound up, mostly with the two kids because they basically have trained him that they are chew toys by the way they play with him, into the crate he goes. When he comes back out after timeout, he knows he has to settle or right back in he goes. I have tried a million times to "train" the two kids not to play with him the way they do if they don't want small nicks and cuts all over their hands and feet lol but I know both will grow out of it. Not to mention Spiel is twice as easy to train than a 15 year old daughter and 11 son. Spielmans' favorite two games are to chase my son as he runs full speed around the house and up and down the stairs with a reward of chewing on an ankle when he catches up, or his other favorite game of chewing on my daughter wherever he can get his mouth while she lays in the floor throwing him around. We have not had any problems with him going in or staying in the crate.
Spiel sounds like he is a little more hard headed than Bogey. He does well with commands when he wants to. Even if he knows he will get a treat. "Come" is the hardest for him. Sometimes he comes running as hard as he can, other times he stares at you with a look like "no, I don't feel like it right now". He really has a mind of his own. He knows there are certain things he is not allowed to chew on, ie the legs on the furniture, and he will walk over, open his mouth wide right next to the leg of the chair two inches away and just stare at you like, "I can if I want, go ahead, look away and see what happens" and as soon as I snap at him he swings his head around like he is pissed at the world.
