Cub, my four month old Labradoodle is very scared of sounds like our diesel pick-up truck, the lawn mower, a cycle passing on the road, etc. The other day my husband started the chain saw to trim a limb and he took out running. He was so scared that he sat a distance away and wouldn't come back until he was sure the chain saw was off. I would like to know if any one else has ever had this problem. I don't know what to do to get him used to these sounds. We are going on our winter vacation in less than two weeks and we will be walking him a lot. We will be at a very nice camping park that is very dog friendly. The only problem is that there will be traffic near on the road ways. How can I get him used to it and not be afraid? He isn't a shy dog like being afraid of people or other dogs. He is very happy other wise.
