I was out walking this evening on a quiet country route with my baby (in pram) and my dog (labrador) who was on a lead. I had just reached a gate when a man appeared at the other side of it with what I am fairly sure was a pocket bully dog who wasn't on a lead. The man shouted over the gate that the dog was friendly. I'm well used to dogs but It was honestly the scariest dog I've ever seen in person (fortunately never encountered an XL!) It probably only came up to my knees but it was so muscular, had an absolutely massive head, very wide stance etc. I waited on the other side for the man to try and get the dog on the lead (there geography of where I was meant I couldn't turn back easily and he was coming that way anyway) which he tried to do, failed to do, and so opened the gate, shouting out that the dog was playful. Said dog then lunged at mine, flinging them both into the pram. My dog was howling and my baby was crying. The dog was still trying to get at my dog and I panicked and ran us all through the gate whilst the man shouted at his dog still completely failing to get him on a lead and the dog ran after us, eventually just stopping and staring us down. I can only assume it actually was playful, as the dog definitely could have hurt mine if it was so inclined, but absolutely nothing about the interaction felt playful, I genuinely felt terrified for my baby's safety. I've absolutely never felt like that around a dog before and still feel really shaken up. AIBU to be so upset? I know it was only a 'pocket' dog but it was much scarier than any other 'scary' dog I've ever seen!
