Dogs HATE to be hugged (and I do it to mine multiple times a day - yikes!) are some other things we do that they dislike:

1.  When we use words more than body language

2.  Petting a dog's face or patting her head

3.  Going for walks without time to explore and smell

4.  Forcing your dog to interact with dogs or people she clearly doesn't like
