puppy rough with older smaller dog

Question
We recently got a male yellow lab who is now 10 weeks old.  We have a 2 year old female 3 pound yorkie.  Before we got the pup we asked our vet if the size would be a problem and he said the yorkie would put the pup in his place.  Every time we have them together the lab gets super excited and jumps at the yorkie.  The yorkie growls and snaps but this only makes the puppy more excited.  It doesn't effect him in the slightest.  He could really hurt our yorkie without even meaning to.  I don't think he realizes he is 4 times her size already.  Our yorkie is scared to walk around the house and spends most of her time hiding on the couch.  What can we do to make it clear to the pup that the yorkie is top dog and he should submit to her.  Help before he really hurts her.

Answer
This is a problem.  My daughter is now fighting it again with her third puppy, a 5 month old Lab and their terrier mix.  What you need to do is not teach him the Yorkie is top dog, but that you are.  The key to most behavior problems is approaching things using the dog's natural instincts.  Dogs see all the people and dogs in the household as a pack with each having their own rank in the pack and a top dog.  Life is much easier if the 2 legged pack members outrank the 4 legged ones.  You can learn to play the role of top dog by reading some books or going to a good obedience class. A good obedience class or book is about you being top dog, not about rewarding standard commands with a treat.

Here are some other useful ways of getting that lesson across to your Lab puppy.  

''Elevation for small puppies:  Sit on the floor and gently put your hands around your pup's middle, below his front legs, and lift him up.  He is facing you.  Hold him for 15 seconds.  Repeat until he no longer struggles.  If he is past 10-12 weeks, lift his front feet off the ground, but don't pick him up.  

Cradling for small puppies:  Hold your puppy gently on his back, as you would cradle a small baby.  If he struggles, hold him firmly until he quiets for 10-15 seconds.  With larger pups, you can do this as your sit on the floor, with your pup between your legs.

Quiet lying down:  Place your pup on the floor on his side, with all 4 legs pointing away from you.  Use your hands on his neck/shoulder area and middle, to hold him in this position.  When he is quiet, praise him.  Lengthen the time that you keep him quietly in this position.  When he accepts this position well, handle his paws and muzzle, while keeping him quiet.''

The quotes mean this isn't my original work.  It is copied from my Puppy Raising Manual.  I have long used these or minor variations of them, and they are very effective.  You may want to give him a belly rub while he is on his back too.  Helps bonding.  There is a big difference between him rolling over and demanding a belly rub, and you choosing a time to roll him over and rub his belly.  The latter cements your place as pack leader.

Support the Yorkie with an ''Ut, ut, ut!'' at the first sign of unwelcome roughness.  You also need to crate the lab when you aren't around.  
It is only natural that a puppy resists its crate at first.  What the puppy
wants more than anything else is to be others, you, anyone else in the
household, and any other pets.  In our modern society, even if we are home,
other things distract us from the attention an uncrated puppy must have.   The
only real solution is to crate the dog when you aren't around.  The dog may be
happier in its den than loose in the house.  It relaxes, it feels safe in its
den.  It rests, the body slows down reducing the need for water and relieving
its self.  Dogs that have been crated all along do very well.  Many of them
will rest in their crates even when the door is open.  I think the plastic
ones give the dog more of a safe, enclosed den feeling.  Metal ones can be put
in a corner or covered with something the dog can't pull in and chew.  Select
a crate just big enough for the full grown dog to stretch out in.

Leave it some toys.  Perhaps a Kong filled with peanut butter.  Don't leave
anything in the crate the dog might chew up.  It will do fine without even any
bedding.  You will come home to a safe dog and a house you can enjoy.

A dog that has not been crated since it was little, may take some work.
Start out just putting its toys and treats in the crate.  Praise it for going
in.  Feed it in the crate.  This is also an easy way to maintain order at
feeding time for more than one dog.

The "shut the puppy in a safe room" is a fallacy.  Very few houses even have a
safe room.  How many of us have a room with a hard surfaced floor and nothing
else?  Most rooms have electrical cords to chew if nothing else.  In addition
to destroying anything a bored puppy finds to chew, it may choke or have
intestinal  blockage from the pieces.  I had a friend that left her dog in a
"safe" room.  It ate a hole in the floor covering.  The safe rooms fail to
give the dog the comfort of the enclosed space their instinct requires.  Nor
do they restrict activity extending the time the dog can go without relieving
itself.

Here is a link to a picture of my daughter's terrier and the Shepherd they had a year ago.  The black ''Lab'' was actually half Golden.  She had a great time playing with the Shepherd.  The 2 older dogs were not pleased.  http://www.photolocker.net/images/Labman/4dogsin05.jpg
