For pups that ambush you and bite your rear end while playing outside, hide a toy or two in the backyard and ask them to find the toy. Bad weather can give puppies cabin fever when they don’t have adequate time outside to run off the energy. Mental stimulation can wear them out, too. Show your puppy a favorite toy and then roll it up inside an old towel and knot it to make a puzzle. Encourage the pup to unravel and get the toy. You can even tie the first toy-in-the-towel inside a second one for more of a challenge to relieve boredom.
With a tie-down, you simply attach your dragline to a fixed object like a fence, stair rail or another immovable object like an eye-bolt in the wall. This exercise uses the same principles as teaching the “wait” command, only instead of closing a door or gate, the pup is confined by the leash. That keeps you safe from mouthing and claws and prevents the pup from jumping up and grabbing. Practice puppy sits and downs while you stay out of range. Only reward the puppy with contact from you when he stays calm with all four feet on the floor.

1. To assert dominance. Whether it's jumping on people or jumping on furniture, both instances illustrate a dog that wants to raise his station in life. By jumping on you or jumping on the couch, he's saying that he's the pack leader--something that you DON'T want to happen, as a dominant dog is much more difficult to train (and can become quite aggressive). In either case, you'll definitely want to institute the proper alpha dog training techniques, if you haven't already.
Why do dogs jump up? A plausible explanation arises from their ways of communicating with each other. A puppy greeting an adult dog often licks the adult’s muzzle -- a polite, deferential behavior. Dogs, of course, descend from wolves, among whom muzzle-licking is how pups get the grownups to regurgitate food for them. Domestic dogs rarely nourish puppies this way, but muzzle-licking has survived, maybe because deferential behaviors are handy for a social animal. Think of humans saying “No, after you.” Muzzle-licking is also an appeasement behavior -- something you trot out to de-escalate a fight. A human might lift up his hands, palms toward the person he’s arguing with.
