Side-by-side comparison of two popular breeds — temperament, exercise, grooming, lifespan and common health issues. Use it to decide which breed fits your home.
The Affenpinscher (3–6 kg, 12–15 years) and the Shih Tzu (4–7 kg, 10–16 years) sit in different — or sometimes overlapping — corners of dog ownership. Here's how they really compare for an everyday Irish or UK family.
Both breeds have similar energy demands — Affenpinscher tips slightly higher but neither is a couch dog.
Grooming is where these breeds really diverge: the Shih Tzu needs significantly more brushing, washing and coat care. Factor in €30–€80 every 6–8 weeks for a professional groomer if you don't do it yourself.
For a first-time owner, the Shih Tzu is much more forgiving than the Affenpinscher.

Confident, curious, mischievous. Forms close family bonds. Less yappy than many toy breeds.
30–45 minutes daily.
Rough wire coat needs hand-stripping every 3–4 months + weekly brush.
Patellar luxation, hip dysplasia (rare for size), heart issues, brachycephalic-lite (mild airway).
Full Affenpinscher profile →Gentle, friendly, slightly aloof, content. Shih Tzus thrive on company and dislike being left alone. They're playful but not high-energy, and generally good with children, other dogs and cats.
30 minutes of daily walking plus indoor play is plenty. Brachycephalic features mean they overheat easily — avoid hot weather and strenuous exercise.
Long double coat. Daily brushing if kept long; most owners choose a "puppy cut" every 4–6 weeks for ease. Hair around eyes needs daily wiping (eye discharge collects). Top-knot to keep hair out of eyes.
Brachycephalic airway syndrome (mild). Eye issues (proptosis — eye popping out — in trauma). Patellar luxation. Hip dysplasia. Dental disease (small crowded mouths). Generally long-lived for a brachycephalic breed.
Full Shih Tzu profile →Adult-only households, owners wanting a small dog with personality and minimal shedding.
First-time owners, retirees, apartment dwellers, allergy-sensitive families.
