We got a bassett hound from the dogs home where he had been a stray. He is a great little dog apart from him barking when we are out of sight. He is kept with 2 other dogs, we have tried the spray collar and also a vibrating collar , none of them work. The main problem is bed time , he is left to sleep in the kitchen with the other dogs but all he does is bark. We have tried to leave him but he will not stop. We have to let him sleep upstairs as to not upset the neighbours. We have also tried to crate him. Does anybody have any idea how yo stop this problem.
