Are they kenneled inside or out side had a dog here like that couple year ago nonstop barking it was a pup I gave shovel shy and he gave him back at 9months old said he was over stocked I knew after 3 days why he gave him back this dog never stopped barking and bouncing of walls non stop it was. I gave to a mate that was low on dogs I asked him after a week how the was getting on he said fine no noise from him he just made out he had him in an open run seemed ta do the trick he still has him 3 yrs later.
