Your dog’s bark might sound aggressive, and in some cases, he may actually feel threatened. An alarming bark could mean he's trying to send out a warning (look for other signs like a stiffened body and forward pounces each time he barks). But most of the time, barking is just a pup’s way of getting your attention because he wants to take a walk, eat a treat, or play. “If you want him to stop, the best thing to do is continually ignore it,” Sotelo says. Eventually, your dog will get the message.
