Today my 6 month GSD puppy behaved very oddly. When we arrived at our usual walk (with him and my other dog) he was very antsy & his back was up. He saw some people through the trees and barked a bit. OK, a bit unusual but on with the walk. Then we came into a clearing (we do this walk nearly every day) and he saw a woman walking along the grass. He froze, then started barking at her before turning and bolting in a blind panic. He scared the life out of me, after 2 minutes calling he finally came back to me and was less than his usual self for the rest of the walk. I've been racking my brains to work out why. He's been extremely well socialised to virtually every situation I can think of, and is a quietly confident dog. Now I'm thinking that i've left some ghastly gap in his socialisation that has caused him suddenly to be so fearful of apparently - nothing. I do know that they go into a second 'socialisation' window, when they become suspicious of things and that life experiences need to be ongoing - but I really hope someone else has had this happen, and it just was a 'one off' or a phase. I work so hard to socialise my shepherds, as a fearful one is my worst nightmare. He did have a scary incident on a different walk on saturday, where a dog bit him on the nose, but I took him back to the same park later the same day and the next morning and he was fine. Could this be a delayed reaction?
Any ideas/experiences welcome. If I need to take remedial action I need to do it now, but I really don't know what caused this. Thanks all
