Recently Rowen's been a bit shy around people. He's always been shy of little kids all the time we've had him, but never of adults/teens. Recently Rowen's been shying away from adults AND little kids even more so. Today we were down at the marina and a little kid wanted to pet him but Rowen ran away and i made him sit, but Rowen made a kind-of growling noise (which he's NEVER done!). I've heard him make this noise at his toys and our other dog when he's playing or when he sees someone outside and is about to bark, but I've always associated it to be one of his playful noises.. but now I'm not so sure. It's pretty startling. We take Rowen pretty much everywhere with us and people always want to pet him but are put off by his shyness.. Any suggestions in helping him building his confidence around people would be great. Thank you!
