The volume of the fluid displaced can then be measured, and from this the volume of the immersed object can be deduced.
The ideal height for an English Cocker Spaniel dog is between 39 cm and 41 cm; (15-16) and for the bitch, it should be between 38 cm and 39 cm (15-15.5) tall.
All spaniels that weighed less than 25 pounds were classified as Cocker Spaniels. There was some dispute, however, over some of the weight designations, so eventually it was decided that type should be more important than weight in determining the breed of the dog. In 1885, England's Spaniel Club was formed.
