Hi I'm wondering if anyone has any advice to lessen my dogs barking. He is only 10 months and I'm pretty sure the barking is an attention thing. I don't mind the occasional bark if he is barking at the door but this is a constant almost howeling noise until I stop what I'm doing. I'm at the point where it is bothering my neighbours. He is a very smart dog but also very stubborn. Anyone have any ideas? Thanks
