Is it True that Dogs Jump on you to show Dominance?

ANSWER: 
Absolutely Not! This is a common misconception that has been reinforced by those who still believe in the outdated "Dominance Theory".

Dogs do not jump on people to establish dominance. Dogs only jump on people because it is the way dogs greet each other. If you watch dogs play, they often jump into each other. Jumping reinforces the greeting for the dog because the human gives attention that results from the jumping. 

If you want your dog to stop jumping on people, stop reinforced for it. There are several things you can do to stop your dog from jumping up on people. 

Teach your dog to sit calmly when guests and strangers enter.
Reinforce your dog for remaining calm.
Turn away and ignore the dog when it jumps.
