[Ponyup]

1st my Logan is never outside alone. We live in town so we always walk him on a leash. We have a retractable leash & he prefers to walk 16ft in front of us. Lately he has begun barking uncontrollably & chasing cars (he's 2). But it's only certain vehicles; such as: mopeds, motorcycles, horse & buggy, jeeps, diesel trucks, & children on bikes (this one really upsets me cause it scares the kids). My Logan is the sweetest & would never hurt anyone. I've found that if I notice a vehicle that will cause this reaction before he does & reign him in & tell him no he won't chase & bark at it. However, if I don't tell him ahead of time he will. How do I teach him that this behaviour is never okay?
