Housetraining a skiddish dog

Question
I have a Chaweenie who is almost six months old. I got her from my in-laws who didn't want her anymore. She is very skiddish. When she has an accident and I approach her to take her to her puppy pad, she pees all over herself. She has been doing this since day one. Also, when she gets excited, she pees. I would take her outside and try to potty train that way, but she's afraid of everything out there too. What can I do?

Answer
You have 2 problems, housebreaking and what is called submissive wetting.  Many dogs eventually outgrow the submissive wetting, but you can reduce it by building the dog's confidence up.  Start with obedience training.  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. Start at http://www.dogsbestfriend.com/  As you praise the dog for following your commands, it will build its confidence.  

Play tug of war with the dog and lose.  However at the end of the game, take the rope or toy and put it up, less the dog becomes confused about who is top dog.  Ropes from the pets' store quickly turn to hazardous shreds.   Ones I made  lasted much better.   Go to a hardware or home center that sells rope by the foot.  Buy 2' of 3/4" poly rope. Melt the ends, and tie  knots in it.   Get them as tight as possible, put it in a vise and pound it with a hammer.  Watch carefully, and be ready to discard when it comes apart.

Finally, make sure it has a den to live in.  If you are not using a crate, buy one.  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.

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.

I think you need to go ahead and start training her to go outside.  Learn to recognize when she needs to go out, and gently carry her out before she starts, and then walk her around until she goes.  
Much of housebreaking is not training the puppy, but making it easier for your
puppy, you, and your carpet while its body to catches up to its instincts. At
around 8 weeks when the puppy goes to its new home, the time from when it
realizes it has to go, and when it can't wait any longer is a matter of
seconds. Only time will fix that. You can hardly be expected to be attentive
enough to avoid all accidents. There is no sense punishing the puppy for your
inattention. It is not fair to punish you either, but you still have to clean
it up if you didn't have the puppy outside in time.

Housebreaking starts before you get home with the new puppy. If you don't have
a crate, buy one. I prefer the more enclosed, den like plastic ones. Skip the
bedding. At first it gets wet, and later it can be chewed into choking
hazards. A wire grid in the bottom will help keep the puppy up out of
accidents at first. They are available with the crates, but expensive and hard to find. A piece of closely spaced wire closet shelving from a home supply place is cheaper. I am now using a plastic vegetable bin with plenty of holes drilled in the bottom. It helps block off part of the crate for the smaller puppy. If you already have a metal crate, covering it may help. Just make sure you use something the puppy can't pull in and chew. Dogs that start out in crates as little puppies, accept them very well. Never leave an unattended puppy loose in the house. If nobody can watch it, put it in the crate. I suggest letting the dog have its crate all its life. A crate needs to be just big enough for a dog to stretch out in.

Choose a command and spot you want it to use. The less accessible to strays,
the less chance of serious disease. If it is a female, choosing a non grassy spot will avoid brown spots later. When you bring it home, take it to the spot and give it the command in a firm, but friendly voice. Keep repeating the command and let the puppy sniff around. If it does anything, praise it. Really let it know what a good dog it is and how much you love it, and maybe a treat. Note, being out there not only means you can praise it, but it also keeps it from being snatched by a hawk. If it doesn't go, take it inside and give it a drink and any meals scheduled. A young puppy will need to go out immediately afterward. Go to the spot and follow the above routine. Praising it if it goes is extremely important. If it doesn't go, take it back inside and put it in its crate and try again soon. Do not let it loose in the house until it does go.

At first it is your responsibility to know and take the puppy out when it
needs to go. It needs to go out the first thing in the morning, after eating,
drinking, and sleeping. If it quits playing, and starts running around
sniffing, it is looking for a place to go. Take it out quickly. You will just
have to be what I call puppy broke until it is a little older. How successful you are depends on how attentive you are.

By the time most dogs are about 3 months old, they have figured out that if
they go to the door and stand, you will let them out. The praise slowly shifts
to going to the door. Some people hang a bell there for the dog to paw. If
your dog doesn't figure this out, try praising it and putting it out if it
even gets near the door. When you catch it in the act, give it a sharp ''Ah, ah, ah!'' and take it out. Clean up accidents promptly. I mostly keep the little
puppies out of the carpeted rooms. Still I need the can of carpet foam
sometimes. First blot up all the urine you can with a dry towel. Keep moving
it and stepping on it until a fresh area stays dry. A couple big putty knives
work well on bowel movements. Just slide one under it while holding it with
the other. This gets it up with a minimum of pushing it down into the carpet.
This works with even relatively soft ones, vomit, dirt from over turned house
plants, or anything else from solids to thick liquids. Finish up with a good
shot of carpet foam. Note, do not let the puppy lick up the carpet foam.
Once the dog is reliably housebroken, your carpet may need a good steam cleaning.

Many people strongly strongly push cleaning up all evidence of past accidents. I am slower to suggest that. Dogs will return to the same spot if they can find it. When you see one sniffing the spot, that is your clue to run it out.
