Hi, Our 10 week old puppy's "living area" is arranged according to Ian Dunbar's setup (crate and potty patch inside the exercise pen). The pup is fine with the crate as long as the crate door is opened. He has no issues sticking his head in to get at a Kong or step in/out as he pleases. However, the moment we close the crate door on him, he starts desperately whining/semi-barking and scratching the inside of the crate. We ignore him even though he goes on for the whole hour. His crate is a full size one (one that will fit him when he gets bigger) with a plastic box inside to make it smaller but with enough room for him to turn around. With or without the plastic box, he goes crazy when he is locked in. He has no issue with the crate when we are driving around with him in it. However, if we are home and we put him in the crate, he goes nuts. Each night, he sleeps outside of the crate within the exercise pen area. We want to crate him so that he can start to train himself to hold his pee/poo. Right now, he pees/poos whenever/whereever he wants to. We tried to keep an eagle eye on him, but, he had peed several times on the floor and the crate already.
