Excellent advice
Thank you, Lisa Allen for the tag and for promoting positive training methods! I couldn't figure out how to respond in the thread, but first of all, know that I am fond of German Shepherds. I grew up with one! And secondly, oh my, the bad advice on that page! It hurts my heart!
Here's the answer to the question of puppy biting. Puppies bite like babies use their mouths when exploring the world around them. You are correct in that some of this biting is associated with teething. Puppies go through a teething period around 4-6 months, like human babies.
Would you (physically or verbally) punish a baby? I certainly hope not! Well, don't (physically or verbally) punish a puppy either for being a puppy! That's cruel and inhumane!
Puppies are separated from their litters when they're just weeks old, and their human owners assume responsibility for the remainder of their parenting. Puppies should not be separated from their littermates and mother before they're at least 8 weeks of age. They need this time to learn how to interact with other dogs, including how hard to bite when playing.
Once in our care, we continue to teach them. We should not try to be dogs, but rather aim to teach our puppies how to get along in our human world and interact with humans.
One important thing we can and should teach our puppies is how to interact with people, including how to inhibit their bite. The proper way to teach this is by simply withdrawing attention when the puppy places its teeth on your skin.
This means you should withdraw touch, avert your gaze and SAY NOTHING. Puppies bite because they want to interact. They want attention. When we want to modify behavior, one of the things we do is remove the reinforcement that would encourage the unwanted behavior to continue.
When you do this, the behavioral term is negative punishment. Negative because we are taking something away (attention), and punishment because if the behavior stops (and it will over time, if you're consistent), the behavioral term for the consequence that stops the behavior is "punishment." In other words, when an unwanted behavior stops as a result of the consequence which follows the unwanted behavior, we call the consequence, "punishment."
So, understand this: punishment does not have to be painful or fear-provoking to stop a behavior. And it should NOT be!
If the puppy starts biting before an interaction starts, in other words, the puppy initiates interaction with biting, then simply avoid reinforcing this behavior. Do not look at the puppy, do not say anything, and do not touch the puppy. This is withholding reinforcement. You are withholding the attention the puppy is seeking, which, if consistent, will cause the behavior to extinguish, or fade away.
Again, the key here is consistency. If the puppy sometimes gets attention, in any form, the behavior will remain strong. What the puppy learns is that biting sometimes works to get attention, and so he'll keep biting because it works! It's like putting money in a slot machine. If a whole bunch of coins falls out of the machine, you're apt to keep putting money in the machine, even if the pay-out is random and infrequent.
I will only mention a couple of things NOT to do. Don't yelp! Don't try to be a dog! You aren't one, and your puppy knows it. Yelping, according to the former director of the Purdue Veterinary Behavior Clinic, Dr. A. Luescher, can further stimulate some puppies, so just don't do it.
Another thing to not do: don't hold your puppy's muzzle and say "No bite!" Again, whether mother dogs bite their puppy's muzzles, I do not recall, but just don't try to be a dog. You aren't one! And don't say, "No bite!" If you think about it, this is rather silly. Saying "No" before "bite" doesn't simplify the command for a non-verbal animal. You could just as well say, "Don't bite" and your puppy would understand just as well.
But rather than trying to communicate with your dog in human language, just use what we call operant conditioning and withhold reinforcement for biting. Operant conditioning is training based on behavior science. In simplest terms, dogs repeat what works, and they don't repeat what doesn't work.
I always tell my students, it's only fair to also teach the dog what to DO instead. So, you can also divert your dog's biting behavior to an acceptable chew toy. The message is, "Chew on this INSTEAD."
Additionally, look for behaviors, such as quiet, calm behavior that you would like to see repeated and praise that behavior. See your puppy chewing on a chew toy you gave him? Praise him! Give your puppy attention for the behaviors you want to see repeated. This is teaching, and that is what you need to be doing with your puppy.
Remember, your puppy is a baby, removed from his littermates and mother and now in the care of another species with whom he has to learn to communicate and interact and get along. Please be kind and help your puppy learn using best practices based on what we know about behavior and learning.
