Classification of dogs: First of all, dogs are divided into several categories, and standards vary from country to country. I use the British standard here. Dogs are divided into working dogs, ornamental dogs, single hounds, pack hounds, sheepdogs and even dogs. Working dogs are generally smart, well-trained and obedient. It has practical value. Ornamental dogs are generally beautiful, but they have no brains, are difficult to train and have poor obedience, but they are very close to their owners. Single hounds are generally smart, energetic and active. Training is ok, and obedience is strong. Most of them are still very beautiful. Hunting dogs are generally smart, energetic, active and greedy. Can't train (although smart, but poor self-restraint). Close to the host, but don't listen to the password when going out. Most of them are beautiful, sheepdogs, very smart and energetic, most of them can be trained and very obedient. Very attached to the master. More canine, very smart, active, like digging holes. Can't train, poor obedience. Not very close to the host. All the above are general situations, but there are exceptions. The following is an introduction to common varieties. Shepherd dog; Scottish shepherd; Most of them are gentle and can be trained. Listen to the master very much. Take it out and stay out of trouble. Blindly priced by the dog market two years ago. Now it's down. It's time to buy it. The disadvantage is that I can't look after the house. Joy associated sheepdog; Timid, smart, trainable. I don't like people other than my master. I will look after the house. Like to scream. An ancient English sheepdog; Gentle and generous personality can be cultivated. It's good for everyone. You don't get into trouble when you go out, and it's suitable for raising anywhere. No housework. German shepherd: misunderstood dog! Stable personality, very easy to cultivate. Very attached to the master. You can do everything you can for your master. Going out without causing trouble (if it is a purebred dog, it often goes out) will look after the house. Du Binquan, working dog; More alert and well-trained. Very obedient to the master, will look after the house. It's dangerous to go out, ie if you've been trained, you'll be fine.

Not for people, but for other dogs (training can solve it). You can look after the house. I like screaming very much Husky; Seeing this dog reminds me of Sue a few years ago! The market is blindly speculating on dog breeds. She has no advantages except beauty. She is clever, but she can't be trained. Like to howl. Obedience to the master is average. I like everyone, so I can't look after the house. There is no danger in going out. Samoyed: Just like huskies. French bulldog; Very clever, but basic training. Have a bad temper.

Going out safely, STANLEY COREN, a professor of psychology at Columbia University in the United States, and 208 local dog training experts, 63 small animal veterinarians, and 14 experts who study alert dogs and guard dogs conducted in-depth interviews and observations on famous dog breeds, and the Vancouver Dog Obedience Club provided a lot of valuable information. Fill in a very complicated and huge questionnaire to rank the dog's work compliance and IQ. The rankings are as follows: 1, Cowley, Baode (also known as Border Collie) 2, Poodle (also known as Poodle) 3, German Shepherd (also known as German Black Back) 4, Golden Retriever) 5, Duberman (also known as Du Binquan) 6, Shetland Shepherd (also known as Hildi) 7, Labrador (also known as Labrador) 8, Butterfly Dog.

Even if the people who train them are inexperienced, they can learn well. Dogs ranked 1 1-26 seem to have to learn simple instructions 5- 15 times. The probability that they will follow the first instruction is 85%. Sometimes they are a little slow to respond to slightly complicated instructions, but this delay can be eliminated through diligent practice. When the owner is far away from them, their reaction may be slower, but even if the trainer is a little inexperienced, there are still ways to train these dogs well. Dogs ranked 27-39 belong to the upper-middle level, and will show incomprehensible reactions after repeating the instruction 15 times, which requires a lot of extra practice, especially in the initial stage. Their response probability to the first instruction is 90%, and their performance depends on the length of practice time. On the whole, the performance is as good as that of the top dogs, but the movements are not so smooth and coherent, and the reaction time is a bit slow. If the host stands a little further away, they may not respond to his instructions. If the trainer is inexperienced, too strict or impatient, these dogs will behave badly. Dogs ranked 40-54 are dogs with medium IQ and moderate obedience. In the process of learning, they basically understand the task after practicing 15-20 times. If they want to get satisfactory performance, they may need 25-40 exercises. If they don't practice, they may forget what they have learned. Their chances of responding to the first instruction are 50%, but only if they have to repeat the training first. If the owner stands close, they will behave better, and if the distance from the owner increases, the dog will behave worse. Better trainers can train these dogs like smart dogs, but inexperienced or impatient people may not be able to control them. Dogs ranked 55-69 may need 40-80 exercises to get the instructions executed perfectly. Even after so much practice, it can't become a permanent habit. If the practice is interrupted for a period of time, they will act as if they have never learned these movements. After practice, the dog's chance of responding to the first command is 30%. Most of the time, these dogs are easily distracted, and they only carry out their master's instructions when they are happy. If the owner stands a little away from the dog, he will spend a lot of time yelling at them, because they are likely to ignore them accordingly. Usually these dogs are rated as "independent, indifferent" and so on. Experienced dog trainer, as long as he is willing to spend a lot of time and pay firm and kind attention to dogs, can make these dogs respond to instructions immediately, but their performance is at best unsatisfactory. Dogs ranked 70-79 usually have to practice hundreds of times to remember the instructions, otherwise they will forget them as if they had never learned this action. Even if I am used to it, I still can't respond to my master's instructions every time. The probability of the first response is 25%. Sometimes they turn their heads to their masters, such as deliberately ignoring their masters or deliberately challenging their authority. When they respond to instructions, their actions are usually slow, uncertain or unwilling. Some dogs have to wear collars to obey, and once they take off their collars, they will be lawless. Ordinary trainers may not be able to control the performance of these dogs. -List of World Famous Dogs-Sports Dogs: Curly retriever, Flat Hair, retriever, German Bristle Wolfhound, Cocker Siddhartha, German Short Hair Wolfhound, chesapeake bay Hound, Golden Hair, retriever Labrador, Gordon Siddhartha, Ireland, Siddhartha boeing da, american water spaniel, British Cocker Cramb, English springer Dog, Field Hound, Irish Water Hound, Weimar Hound, Brittany Hound, Wesley Bristle Wolfhound, Gerry.
