A few months back Copper would not sleep through the night without waking us up to go outside and also to eat. Sometimes more than once. So,after a week straight we put him in his kennel to sleep. We covered the kennel with a light blanket. He would lay down and sleep until the morning. We've been doing this for a couple of months now.
A couple of weekends ago FI's friend came to stay the night. So we moved the kennel in our room. But he kept barking, so we let him out to sleep on the bed. Then we went back to the routine. Now since last Thursday every night when we put him in there to sleep he barks until we come get him. I want to just let him bark until he goes to sleep, but since we live in an apartment I think the neighbors would probably appriciate that we didn't.
I thought this morning about putting a Kong in there with him at night and see if that helps. I'm just at a loss for what to do next. Any suggestions?
