We’ve probably all had the experience of asking whether we could pet someone’s dog only to have the dog completely ignore us or try to run away, and it’s not uncommon for adult rescue dogs to be a little aloof at first. It’s easy to take this personally and think that the dog doesn’t like us, but that’s because we’re looking at it from a human perspective. When two human strangers meet, our rules say that we introduce ourselves and shake hands. Dogs don’t have that rule with other dogs or with humans. Dog socialization is different from human socialization.
