The Bob is a large, square, solidly built dog that somehow manages to look even larger than it is because of the sheer volume of coat surrounding it. Strip away that extraordinary shaggy coat and what you find underneath is a muscular, compact herding dog with a broad head, powerful neck, and a body built for working across difficult terrain. The coat is not decorative - it is functional weatherproofing developed over centuries of working in Britain's wet, cold conditions - but it does tend to dominate the visual impression completely.
The head beneath all that coat is large and capacious. The skull is broad and square, with a well-defined stop. The muzzle is strong and the jaw has a scissors bite. What most people notice first when the face hair is parted, though, are those dark brown or blue eyes - sometimes one of each in individuals with merle genetics - that carry an expression of intelligence and gentle curiosity. The nose is large and black. Most pet Bobs have the hair around the face regularly trimmed for vision and cleanliness, though working standard allows the full natural fall of coat over the eyes.
The neck is fairly long, strong, and well-arched, flowing into a short, compact body. The back is described in the standard as shorter than from withers to ground, creating a characteristic square profile. The topline has a slight rise over the loin that gives working Bobs their characteristic rolling, bear-like gait - an ambling movement produced by the dog's tendency to move both legs on the same side in a lateral sequence. This distinctive gait is part of what makes Bobs immediately recognizable in motion, even from a distance.
Fore and hindquarters are well-muscled, with straight, heavily boned forelegs and well-angulated hindquarters. The feet are round, compact, and thickly padded - built for working on varied terrain in varied weather. The tail, in countries where docking is still permitted, is removed at birth close to the body. In countries where docking is prohibited, the natural tail is long and well-furnished with coat, carried low when relaxed and lifted when the dog is alert or working.
The coat is the breed's most defining physical characteristic and the primary maintenance challenge. It is a double coat - a soft, dense undercoat and a rough, shaggy outer coat that is waterproof when in proper condition. The texture should be hard rather than silky or soft, and the coat should not be flat. Colors accepted by the standard are any shade of grey, grizzle, blue, or blue merle, with or without white. Puppies are born black and white and develop their adult grey coloration over their first two years of life, a transformation that can be quite dramatic.
Male Bobs stand a minimum of 22 inches at the shoulder, with taller dogs common and preferred in the show ring. Females are slightly smaller. Weight typically ranges from 60 to 100 pounds depending on sex and frame, though the coat makes visual weight estimation unreliable - you have to actually put hands on a Bob to get a realistic sense of the animal underneath all that coat.
One detail the coat hides until you look carefully: this is a surprisingly agile dog for its size. The working heritage required a dog that could turn quickly while herding, respond to the sheep's sudden changes of direction, and cover uneven hillside terrain without losing footing. The physical machinery for that agility is there in the well-muscled hindquarters and the sound, compact feet, even if a pet Bob rarely needs to demonstrate it.
Affectionate With Family
★★★★★
A deeply devoted family dog who wants to be in the middle of everything you do - the Bob thrives on closeness and doesn't understand the concept of being excluded.
Good With Young Children
★★★★★
Legendary patience with children earned this breed its reputation as an ideal family companion; they tend to treat small kids as charges to be watched over.
Good With Other Dogs
★★★★☆
Generally sociable with other dogs; the herding instinct occasionally surfaces during play but rarely causes conflict.
Shedding Level
★★★☆☆
Moderate shedding overall - most loose hair stays caught in the outer coat rather than landing on furniture, which regular brushing takes care of.
Coat Grooming Frequency
★★★★★
Among the highest grooming demands of any breed - daily brushing is genuinely necessary to prevent the coat from matting into a solid, uncomfortable mass.
Drooling Level
★★☆☆☆
Not a heavy drooler, though the beard and mustache area tends to collect moisture around the water bowl that transfers to nearby surfaces.
Coat Type
★★★★★
That extraordinary double coat - weatherproof, profuse, and covering everything including the eyes - is the breed's most defining and most demanding feature.
Openness To Strangers
★★★☆☆
Reserved at first introduction but not fearful or sharp - a Bob that has been well socialized warms up steadily and is usually quite pleasant with visitors.
Playfulness Level
★★★★☆
Playful well into adulthood with a genuine sense of humor - one of the few large breeds that maintains a puppy-like silliness for years.
Watchdog/Protective Nature
★★★☆☆
Attentive and will alert on arrivals with a substantial bark, but protective aggression is not characteristic of this breed.
Adaptability Level
★★★☆☆
Adapts reasonably well to different living situations if exercise needs are met, though the grooming demand remains constant regardless of environment.
Trainability Level
★★★★☆
Intelligent and genuinely responsive to training that keeps them engaged - they pick up concepts quickly but may offer creative alternatives to what was asked.
