(2) The nose is moist and cool, not dry, hot or runny. It is especially important to observe the state of the nose. )
(3) The mouth is tasteless, and the teeth are white and neat. Generally, they all grow out in about two months, and the dog's tongue and gums are pink.

The above points are just choices from the perspective of health. Prevention is better than cure. Tell friends that puppies need to have some experience in feeding puppies before weaning in 40~50 days, so I suggest you try not to buy small dogs. (3~4 months old is the age when puppies enter training)
When we see a litter of puppies, if we find that they look roughly the same, of course, the guy who automatically comes over and shakes his head and licks his feet is our favorite. But if you choose, you may find it difficult to wear it in the future, which will make you feel at a loss when you first get a dog. On the contrary, the shy ghost who hides behind at first may be a good companion for those who value a quiet life, although most of them are disliked.
In addition, time also affects the choice of puppies. For example, after a full meal, the strongest often eat the most, and naturally feel sleepy after eating, ignoring you; On the contrary, the one who came out with a warm welcome was a soft little guy who couldn't beat others and didn't have enough to eat.
Experienced breeders can observe the behavior of puppies when they are only a few months old and evaluate their general character, but this is not an objective standard test, which is suitable for all dogs, or for everyone's reference. Based on years of research results, a group of British experts designed a set of "puppy test" method, which was applied to seven-week-old puppies and proved to be very effective. It can be used as a more objective reference, perhaps in the future. The exam lasts half an hour. The way is to take the puppy to a strange and quiet place where no one will be distracted when it is most active. The test includes 1 1 items, and the score of each item ranges from 1 to 6:
First, the social ability tester kneels in front of the puppy for a distance and calls the puppy over. If the puppy's tail is strong and straight, it must be a confident and sociable dog; As for dogs with independent personality, it may not matter; Timid puppies may come, but they will hesitate and hang their tails.
Second, follow the tester to stand up and walk slowly to attract the puppy to follow him, and the confident puppy will follow him actively; The strong will run forward or fall; Timid people will hesitate but stop, while independent people will go elsewhere.
Third, suppress the puppy from falling to the ground, press its chest with one hand, restrict its movement with a little force, and stare at its eyes for half a minute. At this time, the tough ones will struggle hard, and their eyes will not show fear. Timid people will give in and their eyes will wander. This exam is extremely important. The toughest puppies are only suitable for experienced people.
Fourth, after the suppression test is completed, immediately put the puppy in front of you, gently touch its whole body, talk to it gently, let it lick the tester's face, and then bend down. It is more difficult to train a dog that has not forgotten to be suppressed just now.
Fifth, raise your arms and hold the puppy on your chest and stand for half a minute; The purpose is to test how it responds in an uncontrollable environment. If you can relax a puppy in your arms, it will be easier to adapt to a strange environment when you grow up. On the contrary, struggling puppies will be unwilling to accept human domination when they grow up.
Six, find a piece of paper and roll it into a paper ball and throw it in front of the puppy. Usually, its response will be:
(1) ran to the paper ball, picked it up and walked back with the encouragement of the tester. This will be a good dog that is easy to train.
(2) Dogs are not interested in paper balls or even walk away, and their training level is low.
(3) Holding a paper ball and going to the corner to bite and play alone, this independent dog needs an experienced trainer in the future. This test is of course very important for choosing working dogs, and it is also very useful for testing whether it is useful to humans.
Sensory test
First, feel the skin web between the middle toe of the puppy's front foot with your thumb and forefinger, and count it from one to ten in your mouth, and gradually increase the strength of your fingers accordingly; If the puppy has struggled hard at first, it will be overly sensitive to the head circle, restraint and training in the future; Dogs struggling at the highest intensity need tough trainers.
Second, hearing, the sounding instrument makes a loud sound first, and then hides a corner-usually a metal cover or something. After making a sound, the puppy will be frightened and panicked. If it doesn't respond, it should be taken to the vet immediately to check if it is deaf. If the puppy can recover quickly and investigate the source of the sound, it is a dog with excellent grid sensitivity. Dogs with lingering fear and distant sound sources may not be suitable for noisy families.
Third, visually choose to wave some cloth strips in front of the puppy, and the confident puppy will quietly study what this is; Brave people will try to bite it; As for cowards, they have gone into hiding.
