When considering bringing a Giant Schnauzer into your home, it’s essential to understand the typical health issues and lifespan associated with this breed. For an in-depth exploration of breed-specific health issues, refer to Dr. Alex Gough’s book, Breed Predispositions to Disease in Dogs and Cats.

Typical Lifespan

The average lifespan of a Giant Schnauzer is typically between 10 to 12 years, although with proper care, some may live even longer. Their longevity can be influenced by factors such as genetics, diet, exercise, and regular veterinary care.

Neoplastic Conditions 

Giant Schnauzers are prone to several types of cancers, including:

Cutaneous Melanoma: This skin cancer is more common in Schnauzers than in crossbreeds, as noted in a Swiss cancer registry.

Mast Cell Tumors (MCT): These tumors can appear on the skin and have a median occurrence age of 9 years. Schnauzers make up a significant portion of the cases in US referral clinics.

Osteosarcoma: A highly heritable bone cancer, particularly noted in large Schnauzers in Romania.

Metabolic Conditions

Overweight/Obesity: A significant number of Schnauzers are prone to obesity, which can exacerbate other health issues. Studies have shown high rates of obesity in Schnauzers attending veterinary clinics in China and among show dogs in Holland.

Drug Reactions

Low Thiopurine Methyltransferase (TPMT) Activity: This metabolic condition affects how Giant Schnauzers metabolize certain drugs, such as azathioprine, leading to potential myelotoxicity.

Renal and Urinary Conditions

Hyperuricosuria: This condition involves high levels of uric acid in the urine, leading to potential urinary stones. A notable prevalence of carriers for the mutation causing this condition has been observed in the USA.

Kidney Disease: Giant Schnauzers have a higher incidence of kidney disease compared to the general dog population, as seen in studies from Sweden.

Endocrine Conditions

Hypothyroidism: In addition to its genetic predisposition, hypothyroidism in Giant Schnauzers can lead to various symptoms, including skin problems and lethargy. The breed shows a significant prevalence of serum thyroid hormone autoantibodies (THAA) compared to other breeds in the USA.

Understanding these common health issues can help you better care for your Giant Schnauzer. Regular veterinary check-ups, a balanced diet, and appropriate exercise are crucial in managing these conditions and ensuring a healthy, happy life for your pet.

Giant Schnauzer Care and Maintenance

Giant Schnauzers are high-energy dogs that require regular exercise to maintain their physical and mental health. Daily exercise is essential for keeping them happy and well-behaved. Here are some key points to consider:

  • Giant Schnauzers need at least one to two hours of exercise each day. This can include brisk walks, light jogging, or hiking. Regular walks help maintain their physical fitness and provide mental stimulation through exposure to new sights, sounds, and smells.
  • Interactive play sessions are crucial for this active breed. Activities like fetch, tug-of-war, and frisbee can help burn off their excess energy. Incorporating toys and games that challenge their intelligence can also be beneficial.
  • Giant Schnauzers are intelligent dogs that thrive on mental challenges. Puzzle toys, obedience training, and scent work can keep their minds engaged. Training sessions should be varied and interesting to prevent boredom.
  • According to Sylvia Hammarstrom of Skansen Kennel, Giant Schnauzers excel in agility and Schutzhund (IPO) training. These activities provide both physical and mental exercise, helping to channel their energy and natural instincts in a positive way. Sylvia advises, “If you like to do agility and you like to do Schutzhund (IPO) they excel in it.”


Giant Schnauzers have a dense, wiry coat that requires regular grooming to maintain its texture and appearance. Proper grooming not only keeps them looking their best but also prevents matting and skin problems.

Regular Brushing

Brush your Giant Schnauzer’s coat at least three to four times a week to remove loose hair and prevent tangles. A slicker brush and a metal comb work well for this purpose. Pay special attention to areas prone to matting, such as the beard, eyebrows, and legs.

Trimming and Clipping

Regular trimming and clipping are necessary to maintain the breed’s characteristic look. Many owners opt for professional grooming every six to eight weeks. Trimming involves cutting the hair around the ears, paws, and sanitary areas. Clipping can help manage the length of the body hair, keeping it neat and tidy.


For show dogs or those whose owners prefer a more natural look, handstripping is an alternativ-e-archive to clipping. This process involves plucking out dead hairs by hand, which helps maintain the wiry texture of the coat. Handstripping should be done every four to six weeks and can be done by a professional groomer or a trained owner.

Beard and Eyebrows Care

The beard and eyebrows of a Giant Schnauzer require special attention to prevent matting and debris buildup. Regularly comb and clean these areas, ensuring that food particles and dirt are removed. Wipe the beard after meals and trim it as needed to keep it tidy.


Bathe your Giant Schnauzer every four to six weeks, or as needed, using a dog-specific shampoo. Avoid over-bathing, as it can strip the coat of its natural oils. Make sure to thoroughly rinse and dry the coat to prevent skin irritation.

By adhering to these grooming and exercise routines, you can ensure that your Giant Schnauzer remains healthy, happy, and looking their best. Proper care and maintenance are key to managing the unique needs of this majestic breed.

Nutrition and Diet

Sylvia Hammarstrom of Skansen Kennel advocates for a raw food diet, emphasizing the importance of feeding Giant Schnauzers raw, fresh, and uncooked foods to ensure their health and vitality. According to Sylvia, “Dogs need live food, which means raw, fresh, and uncooked. Dogs should eat only meats & vegetables. Avoid all grains.”

Types of Raw Foods

  • Raw Chicken –  Including necks, wings, and other parts, raw chicken is a staple in the diet. Sylvia stresses that raw chicken bones are safe and provide essential nutrients. Cooking chicken bones can make them dangerous as they become sharp and brittle.
  • Raw Meat –  Various types of raw meat, such as beef, lamb, and pork, are beneficial. It’s advisable to buy from a local butcher to ensure quality and affordability. Meat should be cut into pieces rather than ground.
  • Liver and Organ Meats – Essential for a balanced diet, raw liver and other organ meats like heart, kidney, and tripe should be included. These are rich in nutrients like taurine, which is crucial for preventing conditions such as seizures.
  • Egg Yolks – Raw egg yolks, ideally from free-range chickens, should be offered daily. Boiled or scrambled eggs are also acceptable. They provide essential fatty acids and vitamins.
  • Sardines in Olive Oil – Feeding sardines once or twice a week can offer a beneficial change and provide omega-3 fatty acids.
  • Vegetables –  Although not the primary focus, vegetables can be included as fillers. Suitable options include cooked potatoes, carrots, broccoli, and other seasonal vegetables. These should be blended or pulped to aid digestion.

Fasting: Sylvia recommends fasting your dog one day a week after they reach one year old. This practice can help cleanse their system and support overall health.


To maintain optimal health, Sylvia Hammarstrom suggests incorporating several key supplements into the diet of Giant Schnauzers:

  • Vitamin C (Lypo-Spheric Vitamin C) – This powerful antioxidant helps prevent hip dysplasia, arthritis, skin problems, and other health issues. One packet mixed into their food daily provides a significant health boost.
  • Vitamin E – Important for cancer prevention and overall antioxidant support. The natural vitamin E available from specific sources like GNLD is recommended.
  • Omega 3, 6 & 9 –  Essential fatty acids are vital for skin, coat, and overall health. These can be provided through supplements like green-lipped mussel extract.
  • MSM (Methylsulfonylmethane) – This supplement supports joint health and helps the body absorb Vitamin C more effectively. It can be added to their food daily.
  • Colostrum –Beneficial for maintaining intestinal health, given on an empty stomach each morning.
  • Probiotics – Acidophilus capsules support healthy stomach flora and help prevent digestive issues like diarrhea.
  • Alpha Lipoic Acid –  Combined with Vitamins C and E, this supplement boosts antioxidant levels, aiding in cancer prevention and overall health.

Sylvia’s approach to feeding and supplementation is designed to promote the health and longevity of Giant Schnauzers. By following these guidelines and ensuring a varied and balanced diet, you can support the overall well-being of your dog.

Giant Schnauzer Training and Socialization

Training a Giant Schnauzer effectively requires understanding their unique temperament and harnessing their natural instincts. Here are some specific strategies tailored to this breed:

Start Early and Stay Engage

Begin training your Giant Schnauzer as early as possible. Puppies are highly receptive to learning new behaviors and adapting to their environment. Sylvia Hammarstrom advises, “When you get one it should be a puppy so that they can learn your lifestyle.”

Channeling Energy

Giant Schnauzers are high-energy dogs that thrive on physical and mental stimulation. Incorporate activities that challenge their intelligence and physical capabilities. Agility training and Schutzhund (IPO) are excellent options. These activities not only keep them engaged but also enhance their natural working abilities. According to Sylvia, “If you like to do agility and you like to do Schutzhund (IPO) they excel in it.”

Task-Oriented Training

Utilize the Giant Schnauzer’s working dog heritage by teaching them specific tasks. This can include advanced obedience commands, retrieving objects, or even participating in search and rescue training. These tasks provide mental stimulation and a sense of purpose.

Consistency with Commands

Use consistent commands and signals for specific behaviors. This helps avoid confusion and reinforces learning. Given their intelligence, Giant Schnauzers can quickly pick up on inconsistencies, so maintaining uniformity in your training approach is crucial.

Behavioral Management

Giant Schnauzers’ protective instincts and high energy levels can sometimes lead to behavioral challenges. Addressing these issues early and effectively is key to a well-balanced dog.

  • Protective Instincts

 While their protective nature makes them excellent guard dogs, it’s essential to teach them to differentiate between real threats and non-threatening situations. Controlled exposure to various environments, people, and other animals helps in this regard. Socialization should be a structured part of their training regimen, ensuring they remain calm and well-mannered.

  • Aggressiveness

To prevent potential aggressiveness, especially towards strangers or other animals, socialize your Giant Schnauzer from a young age. Gradually introduce them to different people, pets, and settings. Positive experiences during these introductions reinforce good behavior.

  • Excessive Barking

Giant Schnauzers are naturally alert and can be prone to excessive barking. To manage this, identify the triggers that cause your dog to bark and address them through desensitization and redirection. Teaching commands like “quiet” or “enough” can help control their vocalizations. Consistent training and redirecting their focus to a task or toy can reduce unnecessary barking.

  • Chewing in Young Dogs

Puppies have a natural tendency to chew as they explore their environment and soothe teething discomfort. Sylvia Hammarstrom notes, “Once you have a puppy they will put their mouths on everything.” Provide appropriate chew toys and bones to satisfy this instinct. Redirecting their chewing to acceptable items helps protect your belongings. Supervise them closely and remove any items they shouldn’t chew on, offering a toy instead.

Expert Advice

Sylvia Hammarstrom emphasizes the importance of raising a Giant Schnauzer puppy within the context of your lifestyle. Early training and socialization are critical to ensuring that the puppy grows into a well-adjusted adult. “When you get one it should be a puppy so that they can learn your lifestyle. Once you have a puppy they will put their mouths on everything,” she advises.

Following Sylvia’s guidance, focus on integrating your puppy into your daily routine, providing structure, and establishing clear boundaries. This helps them understand their place in the family and adapt to your household dynamics.

By employing these tailored training techniques and addressing behavioral challenges proactively, you can raise a Giant Schnauzer that is well-behaved, balanced, and a joy to have as a companion.

  • Start by researching breeders online and seek referrals from breed clubs and associations, such as the Giant Schnauzer Club of America. Websites like the American Kennel Club (AKC) also provide breeder directories.
  • Arrange to visit the breeder’s facility. This allows you to see the living conditions of the dogs, meet the parent dogs, and observe their behavior and temperament.
  • A responsible breeder will be open to answering your questions about their breeding practices, the health of their dogs, and the socialization practices they use for puppies.
  • Ensure the breeder conducts comprehensive health screenings for genetic disorders common in Giant Schnauzers, such as hip dysplasia, elbow dysplasia, and hypothyroidism. Ask to see health certificates and screening results.
