Dog do not naturally like to be hugged. Some learn to enjoy it because of the relationship that we build with them, and they just want to be touched.
Others find it constraining and will only tolerate being hugged by their families, but not enjoy it. A dog may tolerate or enjoy a hug from a loved family member, but may not be comfortable with a stranger hugging him/her. Hugging a strange dog, or one who is uncomfortable can be dangerous because our faces are right at teeth level if the dog should be pushed beyond his/her tolerance and bites.
