Pay Attention to Their Wants
"Dogs tell us who they are. Some push toys on us all the time and others prefer to take naps," says Woodard. If your dog doesn't seem to be having fun, don't force it. Find what he does like and focus on that. However, if your dog goes from loving long runs to hiding under the bed when you grab your shoes, take notice. A sudden change in personality could be the sign of some sort of health issue.
