This is Kai...  I have had him for three weeks now and got him when he was 14 weeks old. Pretty good little pup, he is just struggling with being in the crate with the door closed.

What a cutie <3 Love his ears! Welcome to the forum

To answer your crate question, it takes time for them to acclimate to the crate. There are some threads in the forum to search on crate training. Best advice wait it out, eventually the crying will stop.

He's absolutely beautiful! Welcome to the forum! My little girl hated her crate at first as well. It took her quite a while to be okay in the crate as long as I was in the room with her. She has separation anxiety so every time I put her in the crate and I leave the room, she freaks out. Now as long as I'm in the room, she's fine. It took her a couple weeks to be okay in the crate while I was in the room, but she wouldn't even go in the crate unless we put her there. We've started feeding her in her crate and giving her treats in there to try and get her more comfortable in the crate and now she goes in there more but she won't stay in there to nap or play with toys. We put her toys in there and she goes in and takes them out to play with them. It just takes time and a lot of work. Also don't let him out if he's crying. Make him sit and quiet down for even a couple seconds before you let him out so he doesn't think he gets whatever he wants by crying.

Welcome to the forum! What a cutie.
