The Affenpinscher might look like a little monkey in a tuxedo, but beneath its scruffy face lies a big personality packed into a tiny body. Sometimes called the “mustached little devil,” this toy breed is known for its confidence, curiosity, and comical charm.
Don't let "little devil" give you the wrong impression, though, Affenpinschers aren't destructive or devilish by any means. They're great companion dogs with a lot of spunk.
In this guide, we’ll dive into the Affenpinscher’s origins, personality, grooming requirements, training needs, and health considerations—perfect for dog lovers seeking a compact companion with loads of attitude and affection.
History and Origin of the Affenpinscher
The Affenpinscher is one of the oldest toy breeds, originally developed in Germany in the 1600s to hunt rats and other vermin in homes, streets, and stables. The name "Affenpinscher" comes from the German word "Affe," meaning monkey—a nod to their expressive, primate-like face.
While their job started as pest control, their playful and devoted nature quickly earned them a place in the home as a cherished companion. Over time, they were bred smaller and became part of the foundation stock for other breeds, such as the Brussels Griffon.

As a result, Affenpinschers are typically more active and task-oriented than other toy dogs bred to be companions. This means they require a significant amount of mental and physical stimulation. They don't need as much room to roam as, say, an Australian Shepherd, but they aren't slouches, either.
The Affenpinscher was recognized by the AKC in 1936 and remains a rare but beloved breed with a loyal fan base.
Temperament and Personality of the Affenpinscher
The Affenpinscher is full of character—feisty, bold, and often downright hilarious. They are confident dogs who don't seem to realize how small they are and will often stand their ground against much larger dogs (or vacuum cleaners).
What's more noble than an underdog who's unafraid to stand up to the big guys?
Despite their tough exterior, Affens are deeply loyal and loving with their families. They tend to form strong bonds with one person but can be affectionate with the whole household. They are alert, occasionally stubborn, and have a mischievous streak that can keep their owners on their toes.
Affens are generally good with other dogs and pets if socialized early, but they may not tolerate rough handling from young children - they will mostly likely scurry away from these "threats" but rough handling could lead to rough housing on the part of your dog, so be careful.
What Does an Affenpinscher Look Like?
Affenpinschers stand 9 to 11.5 inches tall and weigh between 7 to 10 pounds. Their defining feature is their rough, shaggy coat and monkey-like face with a prominent mustache and beard.
They have a square, sturdy build, a short nose, and dark, expressive eyes. Their ears may be naturally erect, dropped, or cropped, depending on regional standards. The tail is often curled or carried over the back.

Their coat is most commonly black but can also appear in gray, silver, black and tan, or red. The texture is wiry and dense, giving them their characteristic scruffy appearance.
Training and Exercise Needs
Affenpinschers are intelligent and quick learners, but their independent nature means they can be a bit stubborn. They were bred to go on their own, make decisions, and hunt vermin without direction from their owners. As a result, they can have a mind of their own at times.
Training should be positive, consistent, and full of variety to keep them engaged.
They don’t need intense exercise, but daily playtime and short walks are essential to keep them mentally and physically stimulated, or else the "little devil" may come out!
Early socialization is key to prevent overprotectiveness and to help them feel confident in a variety of environments.
Grooming and Coat Care
The Affenpinscher’s wiry coat needs regular maintenance to keep it looking tidy and to prevent mats. Weekly brushing and occasional trimming are recommended, but Affens aren't high maintenance.
Routine nail trims, ear checks, and dental care are essential. Like most toy breeds, they are prone to dental issues, so brushing their teeth regularly or using vet-approved dental chews is a must. Without dental care, Affenpinschers are vulnerable to gum disease, and that can lead to significant issues to their overall health and wellness.
Health Issues in Affenpinschers
Affens are generally healthy but, like all breeds, they’re prone to some specific conditions. They have short muzzles, small legs, and the dental makeup of many small breeds, so these characteristics can generate a handful of key issues.
Here are the key issues that Affenpinschers face:
- Patellar Luxation: A common issue in small breeds where the kneecap can slip out of place. Avoid high impact jumping or excessive strain on the hip & joint areas, and it may be a good idea to supplement for bone, joint, & ligament support.
- Dental Problems: Toy breeds often suffer from tooth crowding and plaque buildup. Brushing and dental treats are excellent options to ward off gum disease, and should be utilized throughout your Affen's life.
- Respiratory Sensitivity: Their short muzzle may lead to snoring or heat sensitivity. Watch out for excessive exertion on hot days, and make sure that you're avoiding any extremely hot situations for your dog.
With proper care and vet monitoring, Affenpinschers typically live 12 to 15 years.
Should You Own an Affenpinscher?
The Affenpinscher is ideal for someone who wants a small dog with a big personality. They’re best suited for adult households or families with older, gentle children. Their bold nature and humorous quirks make them wonderful companions for those who can appreciate their independence and charm.
Still, Affenpinschers are active dogs bred to hunt vermin, so they're not lapdogs. They require a relatively active lifestyle, and their small little forms carry a lot of energy. When their mental and physical needs are met, these dogs will certainly curl up by your side.
If you're looking for a low-shedding, apartment-friendly dog that’s full of character, the Affenpinscher may be a perfect match. Just be ready for a bit of sass, a dash of stubbornness, and a lifetime of laughs.
