One of the things that we do when a foster dog barks at night is to put a sheet or blanket over the crate to make it darker and more isolated. Make sure you don't reward the barking by responding and giving the dog attention.
At night, we keep our foster dog (sometimes dogs) in a crate in a separate bedroom (VRWCboy's old room that is now "the dog room") with the door closed. If the dog is barking, sometimes we will stand outside the door and wait for a while and when the dog barks again we will bang loudly on the door and yell "Quiet!" in order to equate a startling unpleasant noise as a response to barking. Only after several minutes of silence will we then go in and talk to the dog and give it attention. Sometimes we will then take the dog outside to see if it needs to take care of toilet business, then encourage the dog with positive reinforcement back into the crate. Reward calm and silence with attention; do not reward barking.
Thank you for the tips. I had him in a crate that is mostly enclosed, like an airplane shipping crate. The collies have their own and that’s where they like to sleep or just get away for quiet time. He is so timid that I am reluctant to use any kind of loud stimulus with him. I have taken him out every time he starts barking but he only has the need for it about 1/3 of the time. He had zero accidents in the house yesterday which is huge. He has chewed through most of his new harness in one spot so I’ve tightened it up. The dog he has bonded with here is getting a little weary of him but hasn’t barked or snapped at him. Oliver will sleep laying right next to Chumley and Chum will let out a big sigh.
