When your puppy reaches adolescence, he may be unable to control his impulses and start to test limits (just like a human child). Adolescent jumping up can turn into “nose boinking” which can lead to broken glasses or even a bloody nose. Jumping up often combines with mouthing behavior where the pup bites and grabs your hands, clothing or even your derriere in a grabbing game of tag.
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.
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.
Puppies should be told from day one, "no jumping." Anything you do not wish your cute little puppy to do when it is full-grown should not be allowed when it is a puppy. Think about the behaviors you allow your puppy to do; is it something you will always allow him to do even when he is full-grown? If the answer is no, do not allow your puppy to do it from day one.
Puppies in human households try to lick the weird, flat, usually bald body part we have instead of a muzzle. When a cute little puppy jumps up to lick face, many people can only say “Awwww!” Hey presto! Jumping up has been rewarded. The puppy’s natural inclination is now a learned behavior. Too bad for the dog when he’s nine months old, bigger and less cute, muddying the pinstripes and knocking Granny to the ground.
