I have some problems with a new dog and I was wondering if you guys could help me out.
My wife and I took in an abandoned dog that a friend of ours found. We've had her for about 10 days now. We've both done a little research and we think we have been following some good practices.
The dog is a 9 pund mixed breed. We think it is a whippet/chihuahua/terrier mix.
The vet estimates she is at least 1 1/2 years old, but no older than 3 years. We have no idea what her history was before she was found.
The majority of the time she is a quiet, good natured dog. However, when it comes time to go to bed and 

ut her in the crate, then we have issues.
We put her in her crate shortly before we go to bed, usually around 10:30pm. Although we don't have to force her to go in, she begins to bark and yelp loudly after we close the door to the room where she is in. It goes on for about 1 hour or even more. We do not go back in the room, hoping that she will finally quiet down.
Eventually she does.
Then, usually around 5am she begins to bark again. We usually get up at 7am so this has not been fun.
When we do let her out she usually goes to the restroom. However, today we discovered that she has urinated in the crate at some point. In addition, she went once again in the crate today when we left her for a couple of hours.
We are looking for help. Although it has been less than 2 weeks, it doesn't seem like anything is working to calm her down at night. We've tried a radio, white noise and even a heartbeat bear made for babies. Nothing calms her down.
My wife and I are home at various times during the day but there are many times when we will have to leave the dog alone for hours without supervision. Eventually we want to get a doggie door, but if she can't get into a routine now, it seems pointless to install it.
We felt like we were doing a good thing taking in this dog. However, if we aren't the right fit for her, we might have to find her another home.
