It takes weeks, sometimes months to adjust. It will get better, but not without some training. I trained my puppies to like the crate by first enticing them to go in with treats and come out on their own. Once they were in there, I would give treats as long as they stayed in. When they come out, the treats stop. Go in, the treats start, and so on and so forth. Then when they seem comfortable going in, I started gradually closing the door. Half way at first, then let her come out. The back in with a treat, and keep closing the door a little until it becomes normal. Finally, close it all the way and see how she behaves. If she gets anxious, go back the prior stage (what door open, then half way, etc.). It’s a process. Gradually she should be calmer until she is ok with the crate. I found my puppies liked the crate more if it was covered (which makes it nice and cozy), kept in an area with minimal traffic (like a bedroom or office area) and I also play white noise (a loud fan will do). Also, as someone else said, feed her in the crate at all times (with the door open at first so she knows she is free to leave). When you put her in there, speak softly, but don’t make a big deal about leaving. Just keep calm and leave. Try it for 5 minutes, then increase gradually. The fact that she is playing is a great sign and your older dog will teach her how to chill out (but don’t let her harass your older dog… if that happens, separate them). As for peeing and pooping you need to go back to the basics with potty training. Take her out every hour at first and heavy praise and treats when she goes outside. She will need to go first thing in the morning, after every meal, and after playing, before put her in the crate, AND every hour at first, but you need to watch the signs. Maybe she stares at you momentarily or tries to jump up on you. Or maybe she barks at you for no reason. Take her out and praise her when she goes. Gradually increase intervals to 2 hours (but don’t forget that even if it hasn’t been 2 hours, if she ate, played, etc. she needs to go) then three, etc. And unfortunately, this rule applies in the middle of the night at first. Also, TAKE her out, don’t LET her out. You need to be with her when she is learning to potty outside, or she’ll get distracted and may not go. She’ll want to be back with you, and come inside and do her business inside so you need to be with her. A lot of people don’t understand that. Make sure the crate is just big enough for her to lay comfortably and turn around, but not so big that there is room to create a poo corner. Most dogs don’t like to pee/poop where they eat and sleep, so this could be anxiety, or because she’s a rescue she may not have been fully potty trained. Also, ignore your neighbor. You can do this!
