Why is professional grooming described as a necessity, not a luxury, for the Yorkie-Chon coat?

Due to the constant growth of their hair requiring clipping every few weeks.

The coat of the Yorkie-Chon is a direct product of the continuous growth pattern inherited from both the Yorkshire Terrier and the Bichon Frise—both possess hair that grows without stopping, unlike fur which follows a set shedding cycle. Because this hair grows continuously, if it is not managed through regular maintenance, it will quickly reach lengths that interfere with the dog's comfort and mobility. This necessitates professional clipping every few weeks to maintain a manageable length, particularly in sensitive areas such as around the eyes and sanitary regions. Neglecting this regular clipping, combined with the need for daily brushing to prevent tangling and matting, confirms that professional grooming is an essential, non-optional requirement for the health and comfort of the dog, elevating it beyond a mere cosmetic service.
