Hi. I just got my 7 week old chihuahua baby last week. I am already so attached to her. I am having a hard time leaving her to go anywhere. I want to cry everytime I put her in the crate. Are they okay being in their crates or do they cry the whole time? I haven't left her longer than an hour yet and even that is very hard for me. Is it as hard for her as it is for me?
