Even Albrecht Dürer depicted the breed’s ancestors in woodcuts, according to the FCI standard. Bushy eyebrows, a ring of hair around the round eyes and a substantial beard are meant to suggest a monkey’s face. Behind that expression is a short muzzle, which matters more here than the coat.

From household dog to a bearded miniature
According to the standard, this was once a household dog in southern Germany, with registrations dating from 1879. Descended from rough-coated pinschers, it formerly came in yellowish or grey coats too; today only black is permitted. The same FCI section includes the Miniature Pinscher (Zwergpinscher) and the Miniature Schnauzer (Zwergschnauzer).
What the standard demands of the head
The bridge of the nose should be straight and short, with the lower jaw extending beyond the upper and curving slightly upwards. A scissor bite, normal in almost all other breeds, actually disqualifies an Affenpinscher. At the same time, the standard requires wide-open nostrils and treats protruding eyes as a serious fault.
Breathing, windpipe and weight
University of Cambridge vets tested 69 Affenpinschers for brachycephalic obstructive airway syndrome, or BOAS, using an exercise test (Tomlinson et al. 2026). 78,3 per cent showed no signs, 5,8 per cent a clinically significant form, and none a severe form. The breed was therefore classed as mild risk. Another finding stood out: 26 per cent showed signs of a collapsing windpipe with a honking cough. Higher weight was also associated with more BOAS, and the authors identify weight loss as a countermeasure.
Knees, eyes and spinal cord
In the same study, 11,8 per cent had a loose kneecap, or patellar luxation. Eyes fared better than in many short-headed breeds: 5,1 per cent showed excessive eye white, and none had a nasal fold. Another concern is Chiari-like malformation with syringomyelia, in which cavities develop in the spinal cord. An MRI study found it in 14 of 42 Affenpinschers, although the sample mainly comprised breeding dogs and patients (Knowler et al. 2017).
Shorter-lived than average
The 338 Affenpinschers in McMillan and colleagues’ study reached a median of 9,3 years, compared with 12,0 for crossbreeds. Their risk of early death was 1,7 times higher; the dataset does not record causes of death.
Small, alert and persistent
Fearless, watchful, persistent and affectionate, sometimes with an impetuous passion, and an agreeable family dog all round: that is how the standard describes the breed. The harsh coat needs regular brushing and occasional hand-stripping.
Who can offer the right home
People seeking a small, alert companion, who will keep them consistently lean and ask about the parents’ breathing tests, kneecap assessments and MRI results before buying.
When another dog is a better fit
If the monkey-like face is the main attraction and you regard coughing, snoring or limping as harmless quirks. With sensitive knees, this is not a dog for young children to carry around either.
To see whether a small, watchful dog fits your everyday life, try the breed quiz, or explore the question further in our book “Welcher Hund passt WIRKLICH zu dir?” (book in German). If you like the beard and temperament but want a longer muzzle, look at the Miniature Schnauzer or the smooth-coated Miniature Pinscher. Find every breed in the Dog Breed Encyclopedia. Small dogs are also waiting for homes in shelters and rescue organisations. For the first weeks, there is the free Puppy Starter Pack.
