The one dog that fits this whole discussion perfectly had a severe case of OCD, alot of anxiety, scared of everything and had alot of quirks. She had these little rituals that she had to do or she wouldn't be comfortable. She had to be picked up a certain way and held facing to the left. If anything touched her while she was on a blanket (like a flea or mosquito), she wouldn't touch the blankets for awhile or until you washed them.
When I got her as a puppy, she didn't know how to bark or couldn't, so she would spend hours at the front door grunting/practicing til she finally pulled it off and she often jump at the sound she would make she finally did. Eventually, She got to where she just had to make this coughing/grunting noise for 5 to 10 mins before she could work out the sound right. Oddly, She was the most human acting dog I've ever seen.
Also, I've had two dogs who had astraphobia. If starts to storm, be prepared to pet or baby a shaky dog til it's over.... It can be cute or really annoying when that happens.
