They will cry the first few nights. You can tell the diffence in a "I have to go potty cry" and a " I'm lost and scared cry". Put a radio on for him, have it on a low volume. Throw in a old shirt of yours, this way he can smell you.
Rocky did that when we first got him, he was 4 years old then and had been in a crate every night sence he was a pup. Finaly i decited to just let him out he was totaly potty traned and never chewed anything. We had no problems he sleeps in our bed now and does not use his crate at all.
It's entirely natural for a new puppy to call out for someone to come when separated. Pups alone in the wild would not survive without this alarm system. Therefore all your new dog is doing is following instinct.
Either in the nesting box or in the wild, a puppy learns very quickly that when separated from the pack, calls for help will allow other members of the pack to quickly locate him.
The first thing you need to know about how to overcome this noise problem is you must ignore it, to go down and scold the puppy would be counter productive, irrespective of whether your appearance is positive or negative the fact that you appeared at all in response to the cries will have reinforced this crying instinct. If noise never elicits a response, then the pup will learn that this method of communication doesn’t work.
What never works is waiting whilst the puppy makes more and more noise then finally becoming annoyed or exasperated and going to the puppy. All that would teach the little horror was being especially PERSISTENT really works!
Punishment does NOT teach your dog to be quiet, any more than it would a baby crying. Punishment or anger would stress him more' and could create behaviour problems or affect your future relationship.
You can help your puppy accept the separation more quickly by introducing the area you want the pup to stay gently and carefully. Feed favourite treats in this area, if you are using a crate then you can leave a stuffed Bone or Kong in the crate as you go up to bed
Crate training, when correctly introduced, speeds up the toilet training process, gives the pup a secure and comfortable den and a bolthole in times of stress. It can also be an invaluable asset when the pup gets older. Situations where a dog may need the ability to accept and relax in a crate include: recovery from medical problems, travel, emergency, and adjustment to a new home or a new family.
have you ever tried putting something in there top help remind him of you... or maybe it's afraid of the dark you can put a night light in side and have it sleep with a couple of toys and a shirt of yours... at lease a shirt you dont want anymore.
When I got Sadie, I spent all of my time the first day working with her and the crate. I would put some treats in there, tell her "it's crate time" and put her in for about 5 minutes to begin with, increasing a little more each hour. She did cry off and on the whole first night, but has been fine ever since. I was also told to put a sheet over her bed because she had a relapse at one point and that has helped. Now she only cries to go out at night.
I put the crate on top of a tote and put it beside my bed so in the night I could put my hand in there to comfort our pup. I moved the crate away from me a little way at a time. Is the crate in the same room with you? Dogs do not like to be separated from you. All of our dogs have their own crate that they sleep in at night and it only took a short time to get them used to it this way.
You just adopted him, sounds to me like yesterday? I'd call the rescue and ask exactly what type of environment he was in in his last home and try to mimic that precisely, down to noise, lighting, etc. if you can't / don't want to let him out for some reason.
Are you sure he slept in the crate at night there? Were there other dogs around? Is he in a room by himself and lonely? Try it a night with letting him out of the crate/in your room, whatever and see how he does. Dont assume he'll be naughty, he might not be ;)
