(1) are all shipped from distant kennels at low prices. On the one hand, there are hundreds of dogs there, and many puppies that have traveled long distances have been ruined.
(2) In addition, when dogs sleep together, bacteria and other diseases can easily infect and carry each other.
(3) In addition, many dogs have congenital physical defects.
(4) What's more, in some dog farms with bad nature, in order to improve the breeding speed, the dogs are even given hormones and pregnancy-promoting injections.
Originally, dogs came into this world as a living life, just to please people and become friends with human beings. Now they are increasingly commercialized. In fact, there is not much difference in the appearance of puppies. Many businesses dye dogs and use high-tech methods to shape them, so customers are more vulnerable. In order to maximize profits, what they want is not quality, but cheap, which leads to their high mortality rate.
Nowadays, buying a dog is the same as buying anything. You can't buy it in a place with strong commercial nature. It is best not to buy in shops, pet shops and other places. Now e-commerce is also developed. Many people like to buy dogs online, but they can't. In large and small urban networks, dog dealers often pretend to be "why do you want to find a new owner to keep the dog at home when the dog is transferred?" I wonder, where did you get so many dogs and move them here by yourself? I calculated that almost 90% of dogs sold online are pretending to be "self-supporting", and the online content is true and false, and it needs your own eyes to identify it. Remember to sign a contract to buy a dog and keep healthy for at least 15 to 20 days. As long as the seller is unwilling to guarantee for so many days, there is probably something wrong with the dog. The more you talk about it, the seller who is anxious for you to buy the dog back must be an "old hand" and will never buy it.
Personally, I suggest you go to Xici Pet Forum and find some pet shops with a slightly better reputation to buy, but most of the puppies in pet shops are not kept at home.
