<human>: We have a male Schnoodle and he's a little over a year now. From the time we got him as a pup, every time we left the house he's cried. We thought he would grow out of it and have tried everything - from treat puzzles to kongs filled with peanut butter to distract him during our escape. We don't make a big deal out of leaving, don't make eye contact and walk out the door. 

He will howl, cry at the highest pitch scream I've ever heard, and go into panic mode when I begin to head for the door. I've sat outside and this goes on for about 10 minutes. He also does this when my husband or I get out of the car to quickly run an errand (while the other one stays with him). 

We recently moved into a new house and the neighbours have said they can hear him through the walls in the morning (townhouse). I can also hear him in MY CAR through the front door. He's all of 10 pounds! 

It's probably not good for his health either to be getting this upset. Does he just have anxiety? Have we done something wrong? How do we stop this?

Can you summarize the given text in a few sentences?
<bot>: MY dog has been crying every time we leave the house for the last year and a bit. How do we help him and why does he do it?
