How big is a fully grown Lancashire Heeler?

The Lancashire Heeler is a small dog.  It is the smallest herding dog, being the same height as the Pembroke Welsh Corgi.  According to the Kennel Club Breed Standard the ideal size for a Lancashire Heeler dog is 10 inches (25cm)  to 12 inches (30cm) and these tend to be average measurements rather than definitive.  In general a Lancashire Heeler bitch will be at the lower end of the scale and a dog at the higher.  The length of a Lancashire Heeler is approximately  1 inch (2.5 cm) longer than height at withers.
