It's not necessarily the dogs on the market that have problems. Maybe many of your friends didn't pay attention when they raised them. Dogs should also be taken care of. What you can eat and what you can't eat, the VIP you mentioned, if it is pure, it is difficult to raise if you don't pay attention. Generally, the reason why dogs get sick is because they run outside and are infected with too many bacteria, which will not be found if they are not careful. When the symptoms appear, it will be too late. It's also important to pick a dog, depending on your eyes. Some dogs can tell at a glance that they are not energetic. They touch their noses, and when they are dry, there is something wrong. The nose should be oily and wet, and the season of buying dogs is also very important. It is generally difficult to raise in winter, so it will be better to raise it when the weather is warmer ~! ! !
