A situation where punitive education method is applicable is to prevent dogs from biting indiscriminately. The first line of defense to prevent dogs from biting is to keep dogs from touching things they shouldn't bite. Put the shoes in the shoe cabinet and close the door; Put the expensive books on the bookcase, not on the coffee table. In short, put away everything that is precious and stay away from the puppy.
However, although it's a good idea to put things away, there are two fatal shortcomings. First of all, it doesn't teach puppies to avoid dangerous things and places. Secondly, most owners underestimate the puppy's ability to find chews. The only way to ensure the dog's environmental safety is to teach him what he can play with with peace of mind and what he should stay away from.
The first step of training is to teach the dog the password "No". Whether the timing of saying "no" is correct or not is an important factor for a puppy to know why he is punished. There is a good training product that can be used to extend the line for this training. Wires covered with rubber insulators are one of the most dangerous things for unsuspecting puppies. For puppies, the touch and biting feeling of the extension cord is exactly the same as that of the power cord of general electrical appliances, except that the extension cord is unplugged.
Put the extension cord in front of the puppy, then leave its sight, hide in the corner, and observe its action (you can also use the mirror to observe). Once the puppy found this new toy and began to want to bite, he immediately said "No" and sprayed it with water; Then give it a fluffy toy to bite. Do this practice regularly until it becomes taboo.
The same method can also be used in training to prevent dogs from biting shoes, books, magazines or other things. If you continue to teach the puppy to bite only what should be bitten by praising or stroking, the behavior of disorderly biting will be greatly reduced.
