Calif. The Bedlington is the only terrier that has all curves and no straight lines. Pet or show there should be no difference in the look of the dog. Only the customers preference as to the length. Show dogs are to be no more than 1 inch on the body and slightly longer on the legs.
Lets start with the clipper work.
Start above the breast bone about 2 inches. The throat is a U shape not a V shape like the poodle. Follow this up to the bottom of the ear. Clear off the cheeks from where the top of the ear sits on head to the corner of the eye, from the eye to the corner of the mouth and clear off the whole underjaw. The inside is cleared off to the tassel.
