Nowadays, most people who buy dogs pursue purebred dogs, and some even spend a lot of money to buy dogs with better pedigree. In fact, many times, raising a dog is just to relax. As long as the dog is cute, it doesn't matter if it is purebred. Recently, a mongrel dog named Cooper became popular on the Internet. This dog is a hybrid of charles king Terrier and Teddy Dog, but it is still loved by many netizens because of its lovely appearance.
In fact, you can get a cute dog by crossing breeds. And compared with purebred dogs, these hybrid dogs also have their own advantages. There are no real purebred dogs. Nowadays, many so-called purebred dogs are artificially bred by crossing two kinds of dogs.
Excellent hybrid breeding must be orderly and meaningful, not ordinary hybridization. Absolute pure breeding is bound to have genetic problems, such as hemophilia in humans and coronary heart disease in dogs, all of which are the consequences of this breeding. Therefore, pure blood dogs must introduce foreign blood at this time to break the congenital diseases brought about by heredity. Otherwise, this pure bloodline will naturally be eliminated, which is also the law of natural selection.
Hybrid dogs have many advantages. First of all, mongrel dogs are not necessarily ugly. Dogs with good looks can still be cultivated as long as they are properly raised. Cooper mentioned above is a good example. In addition, we all know that the physique of purebred dogs is not particularly good, and the physique of hybrids is usually better than that of purebred dogs. Most purebred dogs have some congenital defects. For example, congenital deafness in Damamachi, poodle-epilepsy, boxer-malignant tumor, Du Binquan (details)-bleeding problems similar to hemophilia. Visual diseases that plague purebred dogs include cataract, glaucoma and retinal degeneration that leads to blindness. According to a survey of thousands of dogs by Pennsylvania Veterinary University, they found that purebred dogs are three times more likely to suffer from congenital heart disease than mongrel dogs. According to Dr George padgett of Michigan State Veterinary University, each breed has an average of more than a dozen genetic defects.
Mixed-breed dogs may be in better health.
In addition, the IQ of mixed-race dogs is not low. It can even be said that the IQ of many hybrids is much higher than that of some purebred dogs. Although hybrids have many advantages, it is not so simple to match them well. First of all, the size difference between the two dogs should not be too big, otherwise even if the breeding is successful, there may be dystocia. Not only that, breeding hybrid dogs also needs to consider the problem of survival of the fittest, keep the excellent parts of the dog and make up for some shortcomings with the advantages of another dog.
Therefore, unless we have a clear goal about which breed to raise, it is a good choice for new dog owners to raise a good-looking hybrid dog. But the owner should know something about the characteristics of some purebred dogs, so as to avoid being deceived when he wants to buy purebred dogs in the future because he doesn't know this breed of dogs.
