Hi everybody, this is my first time posting so sorry if its a little chaotic. We just got a new rescue dog, she is about a year old and was a brought in as a stray, so no idea of home life prior. Ive rescued 2 dogs before but now I'm thinking they were easy. We brought her home about a week ago, and we are struggling to get into a routine while we are at work. We immediately started doing crate training multiple times a day, but she never got more than like 10 minutes without completely freaking out, even while we were home. We hired a dog trainer to come and she worked really well with us on the crate. She slept for the first time while we were home, and she slept overnight. So when we left her for work, she did okay for a bit but then was howling, whining, barking, you name it. So, I did a test of leaving her out of the crate with my other dog and just gave her a peanut butter Kong and was able to just sit outside for 45 minutes and she didn't make a peep and eventually just laid down. So we bought a pen, and blocked her off to just one room of the apartment and removed all the pillows and blankets and gave a few toys and we give her a chew/Kong when we leave. Thursday was okay, she didnt really do anything, but today she really seems to be testing boundaries. She seems to keep finding little things and I just don't know what the best thing to do is. I am still working on crate training and she sleeps overnight in the crate, but I don't know how to train her while working a full time job and making sure she stays safe, but isn't stressed out. She doesnt seem to cry and become inconsolable when we leave her out, but I'm scared she's going to get into something she shouldn't or eat something she shouldn't. Literally any and all advice is welcome. I have an appointment with our vet today to get some professional advice as well. I want to get her into a routine, but I dont want to keep changing the environment, but I also just feel so stressed out all the time about what to do.
