Why does my dog bark (appearing aggressive) at other dogs when going for a walk? He seems to only do it when he is on a leash. At times, he will sniff other dogs while on his leash and then just suddenly bark at the dog a ton. He recently started this behavior. What can I do to teach him this behavior is not okay?

There are a few things that could be at play. One, some dogs can get leash shy or leash aggressive, and while they are fine interacting off-leash, may get too overexcited while on leash. Second, Chief may also be very excited and trying to initiate play by barking. Watching his body language can help you determine which is the case -- wiggly soft bodies and play bows can indicate play, while stiff bodies, tail up, hackles showing, etc can indicate distress.
Keeping meetings on leash brief (IE 4-5 seconds max), and then praising Chief and continuing on your walk can help him get used to greeting without it escalating to getting too excited and barking. If he is meeting a new dog that he'll be playing with for longer, several short greetings and walking alongside each other can help him stay focused on the walk without becoming too excited, or moving to an area where the dogs can play off leash can help.
