Both breeds have comparable lifespans — 13–15 years for the Havanese and 10–16 years for the Shih Tzu. You can expect a similar length of companionship from either breed, all else being equal.

The Havanese has a slight edge with children (5/5 vs 4/5). Both breeds can do well in families, but the Havanese's cheerful temperament gives it a small advantage around young kids.

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

The Havanese has a slight training edge (4/5 vs 3/5). Both respond to positive reinforcement, but the Havanese tends to catch on a bit faster.

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

Exercise won't be the deciding factor here — both the Havanese and Shih Tzu need low daily activity (2/5). Neither breed will overwhelm you with exercise demands.

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.

These breeds are near-identical in stature. The Havanese weighs 3–6 kg (7–13 lbs) and the Shih Tzu weighs 4–7 kg (9–15 lbs) — close enough that size alone won't drive your decision.
