This is probably me over thinking it, but please bear with me. We were visiting my parents, with Jasper, when my father's friend popped in. He was wearing a beret (don't ask). Pup went mental. He was growling and barking, yet hiding with his tail between his legs and even tiddled under the table he was that wound up. As soon as the friend took his hat off, Jasper ran over to him licking and cowering. It was really odd and upsetting to watch, but I put it down to him being a stranger. Anyway, this morning DS2 wandered in to the living room wearing a baseball cap and the pup reacted in exactly the same way. He was clearly frightened, but showing false aggression iyswim? Of course, DS2 took his hat off and put his hand out to Jasper, and he ran over to 'make up'. You may remember that I'm the numpty that fell for what might well be a puppy farming scam. So now I'm feeling awful for him and wondering if he has been mistreated by someone in a hat. Is this total bollocks and just the sort of thing bonkers puppies do? Or is this potentially a sign he was mistreated? Either way, how can I help him to not panic/react if someone walks past in a hat? Because with winter around the corner, there will be a lot of hats...
