The French Spaniel is one of the two tallest spaniel breeds, being taller than the English Springer Spaniel. Males can range in height from 22–24 inches (56–61 cm), and females are about an inch shorter. Dogs can range in weight from 45–60 pounds (20–27 kg). A normal dog has a muscular appearance with a deep chest and strong legs. The French Spaniel has eyes of a dark amber colour, and a thick tail that tapers towards the tip. The hair is medium, dense, with long feathers on the ears, backs of the legs and tail. It has some waviness on the chest and otherwise lies flat on the body. The normal colour of a French Spaniel’s coat is white with brown markings rather in shade from a light cinnamon to dark liver.

The French Spaniel has a friendly and outgoing personality and is well balanced and patient. It is not a naturally aggressive dog, is eager to please and thus can be trained easily. A dog of this breed will form a strong bond with its master, being typically a working dog. It has a high level of stamina and requires vigorous exercise.
