General Appearance 
A toy dog, intelligent, alert, sturdy, with a thick-set short body, a smart carriage and set-up, attracting attention by its almost human expression.  
Size 
For the class of dogs and bitches of a small size, the weight should not exceed 7 lb. (3 kg). 
For the class of dogs and bitches of a large size, that is weighing more than 7 lb. (3 kg), the weight should not exceed 11 lb. (5 kg)
for dogs and 12 lb. (5.5 kg) for bitches. 
Note: Type and quality are of greater importance than weight, and a smaller dog that is sturdy and well proportioned should not be penalized. 
 
Coat and Colour
There are two distinct types of coat - rough and smooth. The rough coat should be wiry and dense, the harder and more wiry the better. On no account should the dog look or feel woolly, and there should be no silky hair anywhere. The coat should not be so long as to give a shaggy appearance, but should still be distinctly different all over from the smooth coat. The head should be covered with wiry hair, slightly longer around the eyes, nose, cheeks, and chin, thus forming a fringe. 
The smooth coat is similar to that of the Boston Terrier or English Bulldog, with no trace of wire hair. In the rough-coated type, coat is either: (a) reddish brown, with a little black at the whiskers and chin allowable, or (b) black and reddish brown mixed, usually with black mask and whiskers, or (c) black with uniform reddish brown markings, usually appearing under the chin, on the legs, over the eyebrows, around the edges of the ears and around the vent, or (d) solid black. The colours of the smooth-coated type are the same as those of the rough-coated type. 
Any white hairs in either the rough or smooth coat GROUP V TOYS V-7 are a serious fault, except for “frost” on the black muzzle of a mature dog, which is natural. 
 
Head 
Skull large and round, with a domed forehead. Nose very black, extremely short, its tip being set back deeply between the eyes so as to form a lay-back. The nostrils large, the stop deep. Lips edged with black, not pendulous but well brought together, giving a clean finish to the mouth. Chin must be undershot, prominent, and large with an upwards sweep. The incisors of the lower jaw should protrude over the upper incisors and the lower jaw should be rather broad. Neither teeth nor tongue should show when the mouth is closed. Eyes should be set well apart, very large, black, prominent, and well open. The eyelashes long and black. Eyelids edged with black. 
 
Ears
small and set rather high on the head. May be shown cropped or natural. If natural they are carried semi-erect. 
Medium length, gracefully arched. Forequarters Forelegs of medium length, straight in bone, well muscled, set moderately wide apart and straight from the point of the shoulders as viewed from the front. Pasterns short and strong. 
 
Body 
Back level and short, brisket should be broad and deep, ribs well sprung.

Toes well arched. Black pads and toenails preferred.

Set and held high. If docked to about one third. 
 
Faults
