2 hours plus now that my hound has been howling. He's stuck in his crate per vets orders basically though I'm going to take him out for a walk in a few minutes. I want to be able to click/treat when he's quiet in his crate, but so far he hasn't been unless he has a kong. As soon as he's emptied the kong (which he can now do fairly quickly) he resumes his howling. I'm never going to last a week this way.
