The first groomers or more precisely, the first "shearers" came onto the scene during the Second Empire. The poodle craze among the bourgeoisie at the time had much to do with it. In fact, the "lion" or, Continental clip, still used today dates back to this period. Back then the shearers set up shop in the streets with wooden boxes to provide more extensive services than the superficial grooming that is part of the general care of the dog.
Ever since then, professionals with specialized equipment have been providing grooming services. Grooming in fact is no longer considered to be a luxury, but a necessity for certain breeds.
The first thing you notice about a dog is his coat. The health of the animal is reflected in his coat. Therefore, it is very important to take good care of it. However, everyday grooming performed by the owner in the interest of cleanliness is not to be confused with aesthetic grooming. This type of grooming is what highlights the morphology and the character of a breed, and covers blemishes so as to give the perfect shape. For professionals, grooming is good when it is not noticeable and when it respects the animal.
In fact, country dogs rarely need to be groomed (except for certain breeds such as poodles, for example), unless it is for the personal pleasure of the owner. Professional grooming is required, on the other hand, for show dogs that are carefully scrutinized by the trained eye. In this case, the animal represents his breed and must be perfect.
Clearly, a dog must be in good health in order to be groomed. He cannot suffer from any contagious diseases or dermatosis and must have up-to-date vaccinations (especially the rabies shot in case he bites).
