Just a quick question about crate training. He quite likes his crate and being in it, but he doesn't like being separated with the door closed, which I know is normal. I'm trying to teach him that whining and barking won't get him out of his crate, and reward being quiet. Unfortunately, he doesn't give much opportunity to reward calmness while stuck in his crate. My question is, if he's been whining/barking for a few minutes, how long of a silence/calmness is enough to reward. If he is briefly quiet for 5-10 seconds is that enough for him to associate the treat/release from crate with his calmness or will he still associate the treat/release with the whining he just got done with 5-10 seconds ago? I don't want to reinforce the wrong behavior, but I'm eager to reward silence so I can use the crate as a potty training tool more effectively when I can't watch him every second, and I'd love if it wasn't a howling match each time. Any additional advice about crate-training would be appreciated.
