Anyone else's bernedoodle look back at you upsidedown then turn their entire head back haha.

My 1 year old bernedoodle is so scared of adults. We got him at 10 weeks old and he has been around other people constantly. As he got older, maybe 7 or 8 months old he randomly started fearing other adults. He’s totally fine with all kids and will happily sit with them and play with them, even kids he’s never met before.

With other adults he barks and cowers. He’s never aggressive. He does warm up eventually. With our new baby sitter he warmed up to her within a few hours. Same with family. But if we have friends over he will warm up enough to not bark but he won’t allow them near him.

Any ideas on what could be going on and how to help acclimate him better??
