Hello Everyone!

So Nanook just turned 9 months old, and we just moved into a new smaller place.
He is getting much better with his crate training, will go in willingly, and cries very little when hes in there with the door shut.

I know that it is going to take some time for him to get used to the new place, but until then is there anything I can do to help the process??
When I leave he begins to howl very obnoxiously, and he scratches at the crate. He has plenty of toys/bones/kong toys, I even cover the crate and turn on the TV when I leave. At the old house he was doing very well when I left, so I know a lot if this is due to moving.
I am going to try working him harder before I leave in the mornings as well.

He has a training collar that he responds to very well, he even does excellent off the leash because of it, and I am currently considering buying a bark collar for him. Does anyone have any good experiences with the bark collar?

(please keep all personal opinions of collar use off of the comments. I have had great results with the training collar and as a struggling college student a trainer is out of the options.)

I look forward to hearing your suggestions and advice!

Leaving for a few seconds or minutes, coming back, working up to a longer time just like begining crate training might help. (If you're not already doing that.) I'm sure he'll pick it up faster since he knows how it goes already and just needs a reminder that he'll be okay and you'll always come back.
Petsmart sells something called the sonic egg. It makes a high pitched noise when they bark. I haven't used it myself, but that might be an option you could look into.
I can't say about the bark collar. Hopefully others will chime in.
