Hi, I went through the same exact thing. my baby would cry at night. the best thing is to get her a crate or a play pen( that is what I have), so she can see out, a half bath isnt a good idea, the puppy feels like it is totally cut off from its environment. put it next to your bed... and be tough... when it starts to cry, just ignore it and in a calm but stern voice, tell it to be quiet or No. ITs gonna be tough but remember to spend lots of quality time with your puppy, and let your puppy know when its time for bed. My puppy learned quickly... took about 2 wks. and now she doesnt mind being in the crate.

Maybe he cried at 3:30 because he had to go to the bathroom. I take mine out at 10pm, 2am, and 6am.

Mine always cried in the crate. I did the crate at night thing for about 2wks but my husband gets up at 2am to go to work every morning and he'd disturb the puppy so I decided to just put him in bed with me. It made my life easier. :)

Gracie *hates* the half bath! Occasionally I put her in there if we are going to be gone more than a couple of hours so that she has room to move and go potty (on peed pads) etc. She cries when I shut the door, and when I get home and open it, she screams and runs around frantically! Even when I pick her up she tries to wiggle out of my arms.

She sleeps in a small kennel, it's plenty big enough for her to move around in but small enough that she feels secure. We put her beside our bed the first night and she whimpered at first when we turned the lights out, but I would just tap on the top of the kennel and say "Quiet" and eventually she figured it out. She cried maybe 5 minutes the first night, 2 or 3 the second, and never made another sound from that time on.

I think your little one is definitely showing separation anxiety. I'd try something small beside your bed so he knows you are there within touching distance and that he's safe and secure. Put him in it several times during the day and DON'T let him out if he's crying. Tell him to be quiet and then when he is, he can come out.

It's hard training him, and even harder if he trains you! :)

Update...It actually took 3 nights, and the puppy started sleeping through the night. The first couple of nights were really bad and then on the third night, he started only crying in the early morning. We have a night light in there with him and I would say within the week, he wasn't crying at all. I cannot put him on our bed because he likes to walk around and our bed is VERY high and I was afraid if I was sleeping and he decided to walk off the bed he could get very hurt. I didn't really want to leave him in a crate near my bed because I have two other dogs and I didn't want him to see them and then cry when they got up and started moving around. Also my children come into the room during the night and I knew that would disturb him too. For now things are going very good. He goes in there when I leave during the day and at night, and he has some quiet time. It is his time to sleep and he has food and water there that the other dogs can't get to. I think we have a busy house, and a little time to himself to sleep has to be good for a such a little puppy. Thanks for all of your advice and I am happy that he has gotten used to it, and is happy and resting peacefully when in there.
