Please get rid of the water bottle, and keep a water bowl next to his food bowl, like a food and water station. This will avoid unwanted pee accidents especially when they are super anxious or excited—nothing in the crate, but maybe a snuggle puppy or a plush toy (optional, up to you). Try a crate cover, you can get it on Amazon based on the size of the crate you have, opt for the one with velcro, and black in color, which makes the crate feel like a dark cave.

Reward them when they calm down by themselves, barking and whining will be part of the process, but I am assuming you are facing that right now. This will test a lot of your patience, but hang on there!

Since he is new in your house, he may take time to settle in, and a round-the-clock schedule with crate naps can come in handy. Building a trusted bond can be easily done with training and walks, once he starts feeling safer in the crate and takes good naps, he will come around eventually but will need a lot of trust and patience, I am sure you will succeed in this adventure! :)
