Any suggestions on helping a dog become less reactive to bikes and skateboards? He's a very friendly dog, but he always barks when bikers and skateboarders come by our house. He barks when people walk by, too, but it's a different bark. He's anxious when they're on wheels. Tonight, we took him on a walk, and he was wagging and greeting people. Then a child came by on a bike, and he was barking and wanted to turn and watch him. He got the growly kind of bark going. The child rode his bike into his driveway, all the while Spanky was softly growling. Then the child got off his bike and started walking down the road, and Spanky was wagging his tail and trying whimpering to get to him to greet him.......completely different than when he was on the bike. I'm pretty sure some kids have ridden by and found out they could get him barking with the skateboards and kept it up and got very loud. I came out that day and took Spanky in, but he was quite upset, and I think the kids were staying in front of our house to hear him, but I'm not sure. My son has a skateboard, and Spanky doesn't like it.....he shies away from it, but he hasn't really been around it in awhile. I didn't think he was as reactive as he was tonight with the bike. Any ideas?
