These plants and animals were subjected to artificial selection so that the traits humans wanted in the organisms were selected for and the organisms not having these traits were culled. This, with some modification, is a good analogue for natural selection and artificial selection shows how organisms can be shaped over time with the proper selective pressures. The selective pressure of humans in artificial selection and the selective pressure of the environment in natural selection.

Selective breeding is done to increase the likely hood of certain traits desirable by the breeder. If a dog breeder liked the shape of a dog's ears, she would mate that dog with another dog with similar shaped ears. Incestuous mating occurs quite frequently in animal breeding due to the increased genetic similarity. All dogs belong to the same species, and therefor can produce viable offspring. The reason a Chihuahua and a German Shepard are so different is because of the ancient practice of selective animal breeding.
Most members of a breed are genetically similar due to selective breeding practices that have emphasized specific traits. This similarity can lead to certain breed-specific characteristics and predispositions to certain health issues.
In selective breeding the owners of the pets will choose mates that have selected characteristics that are wanted in the offspring. They may also be repeated with future offspring. In natural breeding it is natural selection that choose and in cats their may even be more than one father and different offspring. In summary the main differences are: Selective humans choose partners with named specific characteristics where as natural if often more first come first served. Also selective breeding is often carried on through the generations whereas natural does not. Similarities are after partners are choose the rest of the process is the same.
Selective breeding, also known as artificial selection, is a process carried out by humans to develop desirable traits in plants and animals. In nature, natural selection is the driving force for change over time, where organisms with advantageous traits have a better chance of survival and reproduction, leading to those traits becoming more common in a population. While similar in principle, natural selection occurs without human intervention, unlike selective breeding.
Selective breeding.
Selective breeding involves choosing specific traits to pass onto offspring, similar to how natural selection acts on variations in a population. Both processes involve the differential survival and reproduction of individuals with certain traits, leading to changes in a population over time. By artificially guiding the inheritance of desirable traits in selective breeding, it demonstrates how the natural environment can also act as a selective force in shaping evolution.

Artificial selection interested Darwin because it demonstrated that traits could be modified over generations through selective breeding. This process allowed humans to intentionally choose which traits were passed on to offspring, leading Darwin to realize that a similar natural process could occur in nature, driving evolution through natural selection.

it is useful to humans because if they are looking into raising a foal, to grow up to be a great race horse they would want the parents to be healthy and quite fit. Also if they wanted to raise it to be a jumping horse, they would have to mate a healthy and muscular mare with a healthy and muscular stud. Hope that helps with your question? x
