Kennelling is invaluable with a lot of breeds. They just tend to get into trouble if left unattended. Hopefully he won't howl and fuss. You might try putting him in for very short periods of time and just leaving the room or stepping outdoors then letting him out with a treat for quiet behaviour. Then extending the length of time slowly....might work well with him. He's a great looking dog but northern sled breeds are all high energy and usually big talkers lol.
