How to tell whether a dog is healthy or not?

The first thing to consider when raising a dog is a healthy dog. Today, let's talk about how to make a dog healthy, regardless of the type and quality of the dog. I will give you some intuitive references to help you judge how to choose a healthy puppy. First, choose a healthy dog. Whether buying a puppy from a dog club or getting a puppy from a friend's house, it is best to choose a puppy born three months later. Because after three months, the puppy's physical condition has been basically stable, the immunity brought by the mother has been exhausted, its own immune system has been established, and its adaptability to environmental changes or resistance to germs is relatively high. Moreover, I have been vaccinated against Dog 2 and Dog 6, and I have adapted to the vaccine. At this time, the puppy's body is much stronger than that of a month or two. In other words, it is easier to choose a healthy dog from three-month-old dogs. Second, judge whether the dog is strong or not. When you face a litter of puppies, you may think that each puppy is healthy and cute, so I tell you not to decide which puppy to have in a hurry, but to observe it for a while. There will always be some differences in the size of a litter of puppies. You should choose a stronger dog. If you like a litter of petite dogs, be careful not to choose the weakest one. Although the weakest one looks delicate and touching, it makes people really want to hold it in their arms. However, for the sake of your dog's healthy growth in the future, don't choose it, because there are usually one or two thin puppies in a litter, also called a litter. Some of them were born with some defects, and some of them died at a very young age. Third, observe whether the physique and organs are sensitive. According to the body shape, choose a few that you think are ok, and see if they have any defects in exercise, congenital bone problems and coordinated walking. Then hold it in your arms (don't stink, because most three-month-old puppies don't take a bath seriously, and they don't hold back their urine, so they often get dirty). Observe the puppy's eyes, nose, teeth, ears and ass. The puppy's eyes are bright and childlike. You should observe whether these lovely eyes are bright, rotate freely, are eager to see new things, have too much secretion around their eyes and shed tears. Check the dog's nose to see if it is cool and moist. A healthy dog's nose should not be dry, nor should it have too much runny nose. It also depends on whether the dog's teeth are neat. The front teeth of the three-month-old puppy have grown up. If the dog's teeth are uneven at this time, it may be a sign of calcium deficiency in the dog, indicating that it is not a completely healthy dog. Open the dog's ear and check it. There are some dirty things or dirt in it, which is not a big problem. The key is to see if there is too much secretion and local redness. Does it feel pain when it is opened? Smell it gently to see if there is a strong smell. You can make some strange sounds to see if its ears are sensitive. Also look at the dog's ass, see if there is sticky stool near the anus, and if the anus is red and swollen. If so, it means that the dog's digestive system is not very good at least at present. In addition, if you want to choose a male dog, you should also touch its reproductive organs (you are going to be its parents, don't be embarrassed), mainly to touch whether its small balls are two. At this time, its balls are still very small, so feel it carefully. Because many male dogs, especially the larger male dogs, have cryptorchidism, which means that there is only one egg. Although it does not affect the reproduction of future generations in theory, it is not very good after all. If it is a dog race, it is a serious problem and you are not qualified to participate in the competition! Fourth, observe the fur of healthy dogs. There are no particularly serious dandruff-like things, no large hair loss or inflammatory skin diseases. Don't worry too much, because some minor skin problems are caused by malnutrition or cross-infection with other puppies, and you will recover soon after you take them home. In short, healthy puppies are lively but not particularly noisy. It moves freely and harmoniously, is sensitive to sound, smell and light, has no diarrhea, and all its senses are clean and tidy. Only such a puppy, if you take it home, can it quickly adapt to the changes in the environment and grow up healthily and happily in its new home! Finally, the standard of healthy dogs is strong body, sensitive and flexible senses, no excessive secretions from eyes, ears, nose, mouth and anus, no peeling and redness, and flexible and active dogs.
