Oh, boy! Homer is scared of bangs and noises. This has been going on for a while. We've been through a few moments especially Oct/Nov last year. New Year we were ready with 'happy drugs' for him which helped a lot and recently he's been a lot better. Last week we were away while storm Katie came over, I sent his dog sitter a message to find out how he was getting on and mentioned he wasn't fond of storms and she replied he was terrified. This week I got the dog desensitising tracks and have started playing them on a very low volume. Yesterday we got caught in a thunderstorm on our afternoon walk. There was not a lot of thunder, a few loud-ish short rumbles then heavy rain and a bit of hail. At the first rumble he turned back to go home. He was reasonably good as he went ahead of me but stopped every now and then to check I was coming and stopped at the usual place to have his lead put back on, but in no uncertain terms he wanted to get back home! This morning he was a little reluctant to go for a walk but as soon as we got going he was fine. we went a slightly different way turning off onto a different path to play ball. This afternoon he was all keen to go for another walk but as soon as I opened the front door there was a bang from builders down the street, a good 10 houses away and not a very loud bang but quite sudden. He would NOT step outside and turned to go upstairs. I left him for a bit, made a cup of tea and got on with some gardening out the back and he came out to the back garden with me. He settled down so after a while I said 'let's go for a walk!' He jumped up all excited, I picked up his led and went to open the front door and he legged it halfway up the stairs. I left the front door open played ball with myself but he wouldn't come down. So I took myself for a walk on my own up to the vet. Had a good chat to the veterinary nurse. I've come home with some Adaptil plug in spray which is now plugged in in the kitchen. Homer has spent all his life in London with traffic, aeroplanes, helicopters, sirens building works (nearly every house in our street has been renovated including our own new roof). He was fine until about two years ago, but I cannot think of any specific trigger.
