The Affenpinscher is a small toy breed with a spirited, terrier-like personality and an almost monkey-like face that earned it the nickname Monkey Dog. The short muzzle and dark, round eyes give the face its distinctive look, while the dense, wiry coat looks neat but shaggy and comes in colors like black, gray, silver, and red.
The breed traces back to 17th-century Germany, where it was first developed to hunt rats in homes, stables, and shops. Over time the Affenpinscher shifted from working dog to companion. The French nickname, diablotin moustachu, means "mustached little devil," which captures the look and the attitude.
These are compact dogs that stand about 9 to 11.5 inches tall and weigh 7 to 10 pounds, with a light, confident gait. They typically live 12 to 15 years.
The personality is as quirky as the looks. Affens are confident, fearless, and famously funny, bold and animated in a way that has earned them the label "a big dog in a little package." They can be willful and independent, but mostly they are loyal, affectionate, and entertaining, and they can suit first-time dog parents who are ready to meet their needs.

Nutrition
Match the diet to your dog's life stage, and consider a formula made for small breeds. Some Affens tend to gain weight, so watch calorie intake, go easy on training treats, and keep clean, fresh water available at all times.
A consistent feeding routine helps:
- Adult dogs: two small meals a day, morning and evening, to hold energy steady and prevent overeating.
- Puppies: three to four smaller meals daily to support growth and help prevent hypoglycemia (low blood sugar).
Slow-feeder bowls can reduce fast eating and related digestive issues, and raised bowls may help older dogs with mobility concerns. The food packaging gives portion guidance, but your vet's guidance is stronger. Measure meals, monitor weight, and adjust portions as your dog ages, since overeating leads to extra weight and joint strain. Regular checkups help fine-tune feeding amounts for your dog's specific needs.
A healthy Affen on a complete, life-stage-appropriate food should get the nutrients it needs, though some supplements can have benefits. Glucosamine and chondroitin support joint health and mobility, omega-3 fatty acids from fish oil support skin and coat, probiotics support digestion, and antioxidants like vitamins C and E support immunity, especially in older dogs. Always talk to your vet before adding any supplement.
Grooming
The Affenpinscher's wiry coat needs regular care to stay in good shape. Brush at least twice a week with a small brush and a metal comb to remove loose hair, prevent matting, and keep the skin healthy as the coat's oils get distributed and air circulates to the skin. Work mats apart gently, paying attention to spots like behind the ears.
The coat grows slowly, so professional grooming every few months is enough to maintain shape and keep the signature monkey-faced look. Groomers often brush the hair on the head forward, then trim it into an inverted V to expose the eyes and a fan shape on the bridge of the nose to keep the eyes clear. Trim any long hair that blocks vision or irritates the eyes. Bathe as needed, usually every few months, with a gentle dog shampoo.
Round out the routine with the basics. Check the ears weekly for dirt, wax buildup, or odor, and clean as needed, since debris can create conditions for ear infections. Trim the nails regularly and brush the teeth often. Watch the eyes for changes like redness, abnormal discharge, or cloudiness, and talk to your veterinarian with any questions.
Exercise
The Affenpinscher is moderately active, so it does need regular exercise despite its small size. A brisk walk once or twice a day is the foundation, and those walks double as a chance to socialize with people and other dogs. Indoor play, both with you and on the dog's own with a toy, can cover much of the rest.
This breed was developed to work and still has energy to burn, but it does not need hours of activity. A short daily walk plus games or indoor playtime is usually enough to tire an Affen out.
Because Affens are smart, they also need mental stimulation so they do not get bored. Many enjoy dog sports such as agility, tracking, and rally and competitive obedience, which give both the body and the mind a workout. Their small size makes them well suited to apartment living, and with dedicated pet parents they adapt to a wide variety of homes.
Training
Early socialization is important for Affenpinscher puppies, as it is for all breeds. Start exposing your pup to new situations and stimuli as soon as you bring them home to help them grow into confident companions. The breed is generally not anxious or fearful, though some Affens may show unease in unfamiliar situations without that early exposure.
Affens have an undeserved reputation for being hard to train. They are independent-minded, a trait that traces back to their rat-hunting roots, and they can be stubborn, but they are intelligent and generally eager to please the people they have bonded with. They respond well to positive reinforcement, like treats and praise, rather than harsh reprimands. Because they bore easily and lose interest in long sessions, keep training short, frequent, and varied, almost like a game. Basic obedience also helps keep their guarding tendencies and barking in check, since the breed tends to be vocal and will sound the alert at changes in its environment.
Affens can make good family dogs, but children should learn how to interact with dogs properly. Because the breed is so small, rowdy play could cause an accidental injury, so supervise all interactions between dogs and children.
