As long as dogs are selectively bred for their aesthetic and physical characteristics, they will continue to suffer. Selective breeding is the process by which humans breed animals to produce desired traits in their offspring. Eventually, dogs were bred less for their ability to work than for their appearance. Selective breeding has its own advantages. Clubs keep track of dogs and their lineage, which is helpful in knowing if the dog has a family history of illness. When breeders use inbreeding or line breeding, it significantly increases the risk of genetic diseases. The alternative to purebred dogs and the health problems associated with them would be to purchase a mixed breed. Genetic diversity is important not only for dogs, but also for all types of animals as well as humans. Pedigree or poison: selective breeding is harmful to dogs. Dogs have been man's best friend for thousands of years and will continue to stand by humanity until one of the species becomes extinct. exist. Dogs have lived alongside humans since they were domesticated by wolves 15,000 years ago (Allan, 2010). This domestication has led to dogs being closely intertwined with the daily lives of many humans. People use dogs as workers, companions and guardians. For some people, dogs are just as much a part of the family as children. Some people even choose to have dogs instead of children. This could be due to a variety of reasons, such as cost, time available, or simply preference. Without dogs, many people's lives would be much worse, as pets impact their owner's life, whether positive or negative. Dogs can be friends and family, or dogs can be a leader to the blind. They can be used to brighten a sick child's day, or...... middle of paper ...... they are generally well diversified, a mixed breed is much less likely to have potentially illnesses fatal. A healthy dog ​​requires far fewer visits to the veterinarian and therefore costs less to maintain. Many people want a purebred dog because it represents value and luxury. What they don't realize is that these purebred dogs often end up in very poor health. It is best for the owners and the dogs themselves if dogs are not selectively bred for specific traits, especially when breeders are careless or unregulated so that inbreeding occurs. Even if a breeder is careful, the limited gene pools of some breeds can cause problems unintentionally. Genetic diversity is important not only for dogs, but also for all types of animals as well as humans. Selective breeding deprives dogs of their genetic diversity and is therefore very harmful to the species..
