Old English Sheepdog vs Shih Tzu: Which Suits Your Home?

The gap here is stark: the OES runs 60-100 lbs and 20-24 inches, the Shih Tzu just 9-16 lbs and 8-11 inches. A Shih Tzu is closer in size to an OES puppy than to the adult dog. This is about as extreme a size mismatch as this site's comparisons get.

The Shih Tzu needs less activity, rated low (2/5) against the OES's moderate (3/5), consistent with its background as a companion breed bred for palace life rather than work. A couple of short walks and some indoor play generally cover a Shih Tzu's needs, well under what the OES wants. Its flat-faced build also makes heavy exertion in heat something to actively avoid.

Grooming ties at very high (5/5) for both, which surprises people expecting the tiny dog to be low-maintenance. It isn't, the Shih Tzu's long, flowing coat needs the same regular professional attention as the OES's shaggy double coat. Shedding is where they split: the Shih Tzu rates a very low 1, close to hypoallergenic, against the OES's high 4.

The Shih Tzu is a near-perfect apartment dog, rated 5 out of 5, against the OES's 2. Barking ties at moderate for both. Alone-tolerance favors the Shih Tzu too, moderate (3/5) against the OES's low (2/5). Size aside, the Shih Tzu was essentially built for the kind of small-space living the OES struggles with.

Trainability ties at a moderate 3 for both, but first-time-owner suitability clearly favors the Shih Tzu, high (4/5) against the OES's low (2/5). Much of that gap comes down to size and manageability rather than intelligence, a stubborn 12-pound dog is simply easier to handle day to day than a stubborn 80-pound one.

The OES edges ahead with kids, 5 versus 4, and with strangers, 4 versus 3. Other dogs ties at 4 for both. Neither gap is enormous, but if a household is weighing toddler-proofing or expects a steady stream of visitors, the OES's slightly higher scores in both categories are worth factoring into the decision.

The Shih Tzu's lifespan range runs wider and longer, 10-16 years against the OES's tighter 10-12. Its ten-condition list includes Kidney Disease, Liver Shunts, and Brachycephalic Obstructive Airway Syndrome tied to its flat face. Hip Dysplasia and Hypothyroidism overlap with the OES's shorter list. That flat-faced airway risk is worth discussing with a vet before committing to a Shih Tzu.

Cost ties at high (4/5) for both, and the dollar ranges sit close: $110-$240 monthly for the OES versus $120-$250 for the Shih Tzu, with first-year costs of $1,700-$3,200 and $1,500-$3,000 respectively. Grooming is the shared big-ticket item here, size doesn't shrink the bill the way it does in most large-versus-small comparisons.
