Activity needs are dramatically different here. The Poodle has high energy (4/5) and needs high exercise (4/5) — think long runs, hiking, or agility courses.

Training difficulty is a major difference. The Poodle (5/5) is eager to please and picks up commands quickly — one of the most trainable breeds out there.

These two breeds look nothing alike. The Poodle is a medium breed at 18–32 kg (40–71 lbs) and 38–61 cm (15–24 in), while the Shih Tzu is a small breed at just 4–7 kg (9–15 lbs) and 20–28 cm (8–11 in).

Both breeds cost a similar amount upfront — $1,000–$3,000 for a Poodle versus $500–$2,000 for a Shih Tzu. Where the real cost differences emerge is in ongoing expenses.

When you live with a Poodle, you'll notice their intelligent, elegant and athletic character in everything they do. A Shih Tzu, by contrast, shows a affectionate, outgoing and happy nature.

Both breeds have comparable lifespans — 12–15 years for the Poodle and 10–16 years for the Shih Tzu. You can expect a similar length of companionship from either breed, all else being equal.

Both breeds shed at the same rate (1/5), so fur management will be identical for either choice. Neither breed will leave much hair around the house.

Both breeds score 4/5 with children, making them equally suitable for families. Either breed would make an excellent family dog.
