Giant Ratzer
The Giant Ratzer is a cross between the Giant Schnauzer 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 Giant Ratzer. Pay special attention to temperament, health issues, and care requirements, as your dog may express characteristics from either parent breed.
Giant Schnauzer
The Giant Schnauzer is a larger and more powerful version of the Standard Schnauzer, presenting a bold and valiant figure with robust and strongly built proportions. Males typically stand between 25.5 to 27.5 inches at the withers and weigh 60 to 85 pounds, while females measure 23.5 to 25.5 inches and weigh 55 to 75 pounds. The breed features a nearly square body proportion, with the height at the withers approximately equal to the body length. This creates an active, sturdy, and well-muscled appearance that denotes speed, power, and balance without appearing bulky or coarse. The chest is moderately broad with well-sprung ribs, and the forechest is distinctly marked by the prosternum. The Giant Schnauzer possesses a distinctive double coat consisting of a soft, dense undercoat covered by a harsh, wiry outer coat that lies close to the body. This weather-resistant coat protects the dog from harsh outdoor conditions and vermin while requiring regular grooming to maintain proper texture and appearance. The coat forms the breed's characteristic beard, prominent eyebrows, and leg furnishings that give the Giant Schnauzer its distinguished appearance. Weekly brushing and regular clipping or hand-stripping are necessary to maintain the coat's proper texture. The AKC recognizes two color varieties: solid black with black undercoat, and salt and pepper, which features banded hairs mixing black and white throughout the coat. The head is strong and rectangular, approximately half the length of the back from withers to tail set. The skull is flat and moderately broad, with a slight stop and parallel planes between skull and muzzle. Dark, oval-shaped eyes convey an alert and intelligent expression that combines spirit with reliability. The V-shaped ears are set high and may be carried erect when cropped, or folded forward naturally when left uncropped. The muzzle is strong and well-filled under the eyes, ending in a blunt wedge with a large black nose. The tail is traditionally docked to the second or third joint and carried high with confident carriage, adding to the breed's commanding and imposing presence as a working guardian.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament Giant Schnauzers are described as velcro dogs due to their strong desire to be involved in family activities. They do not adapt well to being isolated or excluded, and extended periods alone can lead to separation anxiety and destructive behaviors. When bored or under-exercised, these highly spirited and energetic dogs may create their own entertainment through unwanted behaviors such as digging, chewing, or excessive barking. They thrive with owners who can provide both physical exercise and mental stimulation through activities like obedience training, agility, tracking, or protection sports.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Additional health considerations include autoimmune thyroiditis, which affects thyroid function and can cause weight changes, skin problems, and behavioral alterations. Giant Schnauzers may also develop skin conditions such as seasonal flank alopecia, vitiligo, and follicular cysts. Some dogs are sensitive to certain immunosuppressive medications due to low levels of the enzyme thiopurine methyltransferase. Squamous cell carcinoma affecting the toenail beds is noted more frequently in this breed. Regular veterinary check-ups, proper nutrition, and maintaining a healthy weight are essential for monitoring these potential health concerns and ensuring early detection and treatment.
Rat Terrier
The Rat Terrier is a sturdy, compact, small-to-medium sized parti-colored dog that gives the appearance of elegance and fitness, denoting speed, power, and balance. Originally bred for ratting and farm work, this American breed comes in two size divisions recognized by the AKC. The Miniature variety stands at least 10 inches but not exceeding 13 inches at the withers, while the Standard variety measures over 13 inches and up to 18 inches. Weight typically ranges from 8 to 35 pounds depending on size variety. The breed features a body that is just slightly longer than tall, with height measured from ground to withers being slightly less than the length from shoulder point to buttocks. The Rat Terrier possesses a short, smooth, close-lying coat with moderate density and sheen that reflects the breed's overall good health. The coat is tight enough to be functional as a working dog while providing protection from the elements. Whiskers must not be removed for show purposes, emphasizing the natural appearance of the breed. Any variation of pied patterning is acceptable, described as comparatively large patches of one or more colors in combination with white. Acceptable colors include black, chocolate, red, apricot, blue, fawn, tan, lemon, or white, with or without tan points. White on the body is preferred to be between 10 and 90 percent. The head resembles a smooth, blunt wedge when viewed from the front or in profile, widening gradually toward the base of the ears in an unbroken line and well filled under the eyes. The expression is intelligent, alert, and full of interest. Eyes are medium-sized, obliquely set wide apart, and oval in shape, with color varying from darkest brown to hazel depending on coat color. V-shaped ears are set on the top outer edge of the skull, moderately pointed at the tip, and may be carried erect, semi-erect with tipped ends, or button style without preference. The overall appearance conveys a hard-muscled dog with smooth lines under taut skin.
Key Characteristics
Temperament Temperament Temperament Temperament Temperament Temperament Rat Terriers are highly intelligent and quick learners, though they possess the terrier trait of stubbornness and an independent mind that can make training challenging. They respond best to positive reinforcement methods with consistent, patient training that keeps sessions short and engaging. Their strong prey drive means they should be kept on leash or in secure areas, as they are impulsive explorers who will take off after anything that runs. These clever problem-solvers are notorious for figuring out escape routes from yards, making secure fencing essential. Despite their terrier heritage, Rat Terriers rank in the lower-to-middle section of typical terrier intensity, making them more adaptable family companions.
Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Health Considerations Cardiac disease, particularly valvular disease, is the leading cause of death in older Rat Terriers, though this typically does not manifest until the senior years. Valvular disease often presents without obvious symptoms initially but may be detected through heart murmurs during veterinary examinations. As the condition progresses, signs of heart failure including weight loss and fatigue may appear. Epilepsy has also been noted in the breed. Regular veterinary check-ups, maintaining appropriate weight, proper dental care, and prompt attention to any unusual symptoms help ensure Rat Terriers live their characteristically long, healthy lives.
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 Giant Ratzer 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 Giant Schnauzer and Rat Terrier to fully understand the range of possible temperaments, health concerns, and care requirements.
