Poppy didn't bark at all until he was a year old. He's seven and a half now. He isn't neutered. He's very affectionate with us and is always right at our heels. He's quite aggressive, but only with other males. He lives with an old cat. He starts barking hysterically when we feed the cat in the basement,
when I get out of the car and leave him inside, when the intercom rings, on walks, in the woods... He also chases after cars, barking all the way along our garden fence by the side of the road. We feel like this erratic behaviour is getting worse as the years go by. What can we do to re-train him, or is it too late? Should we see a dog behaviourist? Thanks for your help.
