When dog and I are at hunting camp, cousin usually comes over from the farm on his Yamaha ATV. Dog can hear that thing coming 10 minutes before he gets there and is fired up.
Used to have a Kawasaki myself.and the dog never reacted to the sound of it coming out of the woods and into camp. Same for ATVs running down the gravel road past camp. Just looks, no reaction like when her favorite visitor is coming from a half mile away. Dogs can learn. Sometimes they even learn something useful.
