I don't have a dog, so I don't know much about the issues or challenges that might arise in the process of washing a dog. From what I know, most Korean dog owners seem to wash and groom their dogs at home. However, most Koreans live in apartments without a separate garden, so they have to raise dogs inside the house, and the number of people who want to provide special services to their dogs and spend much money is increasing, so more and more people are looking for professional dog groomers. I think that if dog owners bathe their dogs at home, the house may become messy and it may be difficult to trim the dog's fur considering the characteristics of the dog's fur. On the other hand, professional groomers are likely to be able to provide a variety of services taking into account the various characteristics of dogs. I think that, just as people, especially women, go to hair salons to get their hair trimmed, in the future, most dogs will have their fur trimmed by professional groomers.
