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. I take a #40 against on my showdogs or a #10 against on pets faces. 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 ear I use a #40 or #50 against regardless of showdog or pet. The tassel will be the bottom 1/3 or less of the ear. Make an inverted V. The inside is cleared off to the tassel. The bottom of the tassel should be trimmed straight accross to the desired length.
The tail is clippered to form a V at the top base of the tail just to where the testcles or vulva start. The underside is cleaned off. Clean belly as normal.
The pet I will take a #4f,5f or 7f (depending on customer preference) off the breast, down the sides of the neck starting under the ear,shoulder blades down to the front leg. Leaving the back of the head and neck. This you will blend later. The sides of the body I use #1duck,1 1/2 duck or 2 duck depending. Starting where you left off just behind the shoulders. Duck him along the sides to the rear. Leave the top of the back, that will be scissored later to form the "roach". Remember the Bedlington is supose to be a slab-sided dog not barrel chested. They are supose to be a fast looking dog, which they are.
Now to scissoring the head. Part the head from the nose to the top of the head. Scissor anything that is sticking out straight up and down from the side of the cheeks. Muzzle should be the same length as the top. The top of the head should be left longer to give it that long look. Turn the dogs head to profile and scissor from the nose to the top of to give it a slight arc look. Don't cut eye holes. If the above is followed they should be able to see without cutting any eyeholes. The neck should follow the same procedure of parting the hair.
The top of the shoulder blades should be short. The "roach", the top of the back, should be parted also. The highest part of the roach should be even with the tuck up. The tuck up should be as high as possible sloping down to leave the chest just past the elbow, to be as deep as possible. Scissor the rear so it slopes off with the tail. Scissor your V on the tail.
The forelegs are to be straight and wider apart at the chest than at the feet. There is a slight bend to pasterns which are long sloping. Stifles well angulated. Hocks well let down. The feet should be hare feet.
Well I think that completes the dog. It also helps to have a picture of a well groomed Bedlington along with you to refer to. Most of all don't stress and have fun. If you have any questions please feel free to e-mail me at wildwynd@juno.com
