What these breeds have in common
The Non-Sporting Group is where the kennel club put the breeds that did not fit anywhere else, and it is honest to say so. Poodles, Bichons Frises, Bulldogs, Dalmatians, Chow Chows, Shar Peis, Boston Terriers, Lhasa Apsos, Shiba Inus, Keeshonden and Schipperkes all sit here.
There is no common ancestry, no common job and, most importantly, no common coat. This one group contains a curly coat, a silky coat, a smooth coat and one of the heaviest double coats in dogs, and two dogs in it can need appointments with nothing whatsoever in common.
It is therefore the group where owners most often guess wrong about what their dog needs, and where the group name is least worth reading.
What this group means for grooming
No single coat type, which makes it the group where owners most often guess wrong. Bichon and Poodle sit here alongside the Bulldog.
What actually decides the grooming
The coat type, not the group. It sets the tools, the interval and the price, and two dogs in this group can need completely different appointments.
