The American Cocker Spaniel is the smallest member of the gundog group.
It's slightly smaller than the English Cocker Spaniel, with a much heavier coat, shorter muzzle and a more domed head.
Although the American Cocker Spaniel will point and retrieve game in the field, it is more often kept as a family pet, you will also often see them as show dogs.

The Cavalier King Charles Spaniel is a different breed from the King Charles Spaniel, although it is a direct descendant.
The easiest way to differentiate between the two is by looking at the head. The Cavalier King Charles has a fairly flat head, whereas the King Charles Spaniel's head is quite domed.
They're small but well-balanced, eager and affectionate dogs. Their are around 30-33cm (12-13") in height, and can weigh between 5-8 kgs (10-18 lbs).
The Cavalier King Charles Spaniel has eyes that are very gentle, large and round but not prominent, and their ears are long and set quite high. They have wide open nostrils.
Their coat is long and straight, and very silky, sometimes slightly wavy, and has plenty of feathering. They share the same coat colours as the King Charles Spaniel; black and tan, red, white and red, and a tricolour, white with black and tan markings.
