Friendly, Skinny and Skittish

He's so skinny and today shows him in backyard with friend and her two daughters who rode over on their Mule - he is now friendly to everyone, all ages,- skittish -like when they got out the golfclubs and then he was scared of the golfbag when it was just outside the door and he wasn't used to it being there - also - afraid of leash.
