Determining the quality of a Cavalier King Charles Spaniel puppy involves observing several key characteristics, including its head, coat, and overall body structure. Careful evaluation in these areas can help you identify a well-bred puppy.

Evaluating Head Features
A purebred Cavalier King Charles Spaniel should have a head that is of moderate size, slightly rounded on top, and appears relatively flat. The eyes are large, round, and a deep, clear brown, giving them a bright and intelligent appearance. The ears are set high, are long and wide, and hang down. These are adorned with plentiful feathering, contributing to their elegant and noble look.
Examining Coat Characteristics
The coat of a Cavalier King Charles Spaniel is of medium length, silky, and may have a slight wave. Notable feathering is present on the ears, chest, legs, and tail. The coat comes in several colors. One variety is a rich chestnut with pearly white markings. Another is a deep black with pearly white markings and tan markings on the cheeks. A third is a rich red with bright tan markings above the eyes, on the cheeks, ears, chest, legs, and under the tail.
Analyzing Body Structure
The neck of a Cavalier King Charles Spaniel is of moderate length, well-muscled, and slightly arched. The topline should be level at all times. The body is short, compact, and the chest is moderately deep. The legs are sturdy and strong, and the tail is set on at a moderate level, hanging down naturally. A key characteristic is that the tail typically does not move much when the dog is in motion.
Assessing Gait and Movement
When walking or running, the Cavalier King Charles Spaniel should move with a smooth, elegant gait. The front legs reach out well, and the hindquarters provide strong drive. From the side, the stride should be balanced and not rushed or hesitant. From the front and rear, the movement should be straight, with no extraneous motion.
Are Cavalier King Charles Spaniels Intelligent?
Cavalier King Charles Spaniels are inherently intelligent dogs. With consistent training, they can quickly learn various commands and are typically very cooperative. They are also active dogs that require daily exercise to stay healthy and happy. Therefore, owners should ensure they have ample opportunities to engage in physical activities.
