My family owns a 10-month-old dog and it's recently started chasing (and barking) after motorcycles as they drive past our place. It's very dangerous for our dog, and not a good experience for the motorcyclists either!

I've never dealt with a dog that chases cars before, as I've only ever had 100% indoor dogs. This dog is 80% outdoors, although he sleeps indoors at night.

Anyone have a dog that chases cars? How do you train a dog to stop doing this?
