Rattle Griffon
The Rattle Griffon is a cross between the Brussels Griffon and the Rat Terrier. Because each hybrid inherits a unique combination of traits from both parents, we recommend thoroughly researching both breeds before choosing a Rattle Griffon. Pay special attention to temperament, health issues, and care requirements, as your dog may express characteristics from either parent breed.
Brussels Griffon
The Brussels Griffon is a small, sturdy toy breed that presents a distinctive appearance often likened to that of an Ewok from the Star Wars films or described as possessing an almost human expression. This compact dog typically weighs between 8 and 12 pounds, with the breed standard specifying that quality should never be sacrificed in favor of size and that dogs should not exceed 12 pounds. Height generally ranges from 7 to 10 inches at the shoulder, with a square, thickset body that conveys robustness despite the breed's diminutive stature. The overall impression is of a well-balanced, alert little dog with remarkable presence and personality. The Brussels Griffon comes in two distinct coat types that are considered variations of the same breed in American registries. The rough-coated variety features a harsh, wiry, dense coat that stands somewhat away from the body and produces the characteristic bearded face with profuse eyebrow furnishings. The smooth-coated variety, sometimes called the Petit Brabançon, displays a short, tight, glossy coat that lies close to the body. Both coat types require regular grooming, though the rough coat demands more extensive care including hand-stripping for show dogs or clipping for pet maintenance. Acceptable colors include reddish-brown, black and reddish-brown mixed with a black mask, black with uniform reddish-brown markings, and solid black. The head is perhaps the breed's most striking feature, being somewhat large in proportion to the body with a distinctly domed forehead. The skull is round when viewed from the front and in profile, with a deep stop creating the characteristic pushed-in face. The muzzle is very short and set back under the eyes, contributing to the brachycephalic structure common to the breed. Large, dark, widely set eyes project a warm, expressive quality that gives the Brussels Griffon its famous almost-human expression. The black nose is extremely short with large, open nostrils set back between the eyes. Small, high-set ears may be cropped or left natural, with natural ears carried semi-erect. The tail is set high and typically docked where permitted.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament The breed's interactions with children and other pets require careful consideration. Brussels Griffons may not be ideal companions for households with young children, as they do not tolerate rough handling and may become defensive if treated too boisterously. They typically get along well with other dogs in the household, especially when raised together, but may display aggression toward unfamiliar dogs regardless of size differences. The breed's terrier heritage occasionally surfaces in prey drive toward smaller animals, though this varies considerably among individuals. Brussels Griffons require a moderate amount of daily exercise consisting of walks and play sessions, but their primary need is for human companionship and interaction.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Orthopedic and neurological conditions also warrant attention in the breed. Patellar luxation, where the kneecap slides out of its proper position, occurs with notable frequency and ranges from mild cases requiring no intervention to severe cases necessitating surgical correction. Eye problems are common due to the breed's prominent eyes, including conditions such as cataracts, progressive retinal atrophy, corneal ulcers, and eyelid abnormalities. Chiari-like malformation and syringomyelia, conditions affecting the brain and spinal cord, have been documented in Brussels Griffons and can cause pain, sensitivity, and neurological symptoms. Dental disease develops readily due to the small jaw and crowded teeth, requiring diligent home dental care and regular professional cleanings. Additional concerns include hip dysplasia and various skin conditions.
Rat Terrier
The Rat Terrier is a compact, well-muscled small to medium-sized dog that presents an appearance of elegance combined with athletic capability. This breed comes in two distinct size varieties recognized by major kennel clubs: the Miniature, standing between 10 and 13 inches at the shoulder, and the Standard, measuring over 13 inches up to 18 inches in height. Weight varies proportionally with height, though the breed standard emphasizes moderate bone structure and a well-balanced physique rather than specific weight requirements. The body is slightly longer than tall, with a level back, well-sprung ribs, and a moderately wide chest that extends to the elbow. The breed's coat is short, smooth, dense, and characteristically shiny, requiring minimal grooming to maintain its healthy appearance. Rat Terriers display a distinctive pied coloring pattern, featuring comparatively large patches of one or more colors combined with white. Acceptable colors include black, chocolate, red, apricot, blue, fawn, tan, and lemon, often appearing with tan points. The breed standard specifies that white should comprise between 10 and 90 percent of the coat, and solid-colored dogs without white markings are not permitted. The intense, dark shades with clearly defined color delineation are preferred in show specimens. The head resembles a smooth, blunt wedge when viewed from the front or in profile, widening gradually toward the base of the ears. The expression is intelligent, alert, and full of interest, achieved through obliquely set oval eyes that are positioned wide apart. Ears are set on the outside edge of the skull and may be carried erect, semi-erect, or tipped. The muzzle is strong and slightly shorter than the skull, tapering slightly toward the nose. The tail may be naturally bobbed, docked, or left full length, carried from slightly below horizontal to nearly erect depending on the dog's mood and attention level.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament Rat Terriers generally do well with children when raised together, though their terrier instincts may surface around very young or boisterous children. They can be somewhat reserved with strangers, making them excellent watchdogs without excessive barking. The breed typically coexists peacefully with other dogs, especially when properly socialized from puppyhood. However, their strong prey drive makes them unsuitable companions for small pocket pets. Without proper leadership and consistent boundaries, some individuals may develop small dog syndrome, attempting to assume pack leader status within the household.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Eye and cardiac conditions also warrant attention in the breed. Progressive retinal atrophy, a degenerative eye disease that gradually leads to blindness, has been documented in the breed. Regular ophthalmologic examinations can detect early signs of this condition. Some lines may carry genes for primary lens luxation, another serious eye disorder. Cardiac disease, including various heart murmurs and conditions, should be screened through veterinary cardiac evaluations. Additionally, the breed may be affected by congenital hypothyroidism, Von Willebrand's disease affecting blood clotting, and dental issues common to small breeds. Maintaining proper dental hygiene through regular brushing and professional cleanings helps prevent periodontal disease.
Important to Remember
Each hybrid dog is unique and may inherit any combination of traits from either parent breed. The information above represents the characteristics of the purebred parent breeds. Your Rattle Griffon may favor one parent over the other or display a blend of both. We strongly encourage you to read the complete breed profiles for both the Brussels Griffon and Rat Terrier to fully understand the range of possible temperaments, health concerns, and care requirements.
