Hi everyone. I’m a new member and hoping I can get some advice. I have recently adopted a 4 year old border collie for a shelter after him being there two months, his first day has went pretty well so far but I noticed that when a train went by two separate times (I live up a hill from a rail way line) he left the room to go outside the 15 minutes and just sat by himself and then the second time he left the room and sat at the front door. I’m worried in case he is scared of the sound, it’s not a terribly loud noise but it would certainly be strange for a dog who hasn’t heard it before. I had a dog before him who never cared about it. I understand this is his first night so of course it is a massive change for him and it will take time. I am just really hoping he likes it here and would anyone have any tips of how I can desensitise him to the noise and help him settle even more in my home?
