Old English Sheepdog vs Yorkshire Terrier: Which Suits Your Home?

Put these two side by side and the mismatch is almost comic: the OES tops out around 100 lbs and stands up to 24 inches, while the Yorkshire Terrier maxes out at 7 lbs and 8 inches. That's roughly a 14-to-1 weight difference between the top ends of each range — one of the widest size gaps on this site.

Despite the size gap, energy levels sit closer than you'd expect — moderate (3/5) for both breeds. Exercise need tips slightly toward the OES, moderate (3/5) against the Yorkie's low (2/5). Neither dog needs marathon exercise, which is a little surprising given the OES's working-dog background. A Yorkie's short legs and small size naturally cap how much exercise it needs regardless of temperament.

Here's the real surprise: both breeds rate very high (5/5) for grooming need, tying despite being nearly opposite in size. The OES's long double coat mats without regular brushing; the Yorkie's long, silky coat needs just as much upkeep to avoid tangles, even with far less of it. Shedding splits sharply — high (4/5) for the OES against very low (1/5) for the Yorkie.

The Yorkie wins for small spaces — very high (5/5) apartment suitability against the OES's low (2/5), tracking with the size difference. Barking runs the other direction, though: high (4/5) for the Yorkie against moderate (3/5) for the OES, so a small apartment with a Yorkie may mean more noise, not less. Both tie at low (2/5) for tolerating time alone.

The Yorkie rates slightly better for first-time owners, moderate (3/5) against the OES's low (2/5), but trainability itself ties at moderate (3/5) for both. Neither breed is difficult to train exactly — they're just not the most eager-to-please dogs on this site. Both benefit from early, consistent routines rather than one dramatic training push, and patience matters more than raw trainability score for either.

The OES rates ahead of the Yorkie across the board: very high (5/5) with kids against moderate (3/5), high (4/5) with other dogs against moderate (3/5), and high (4/5) friendliness to strangers against the Yorkie's low (2/5). If your household is loud and full of visitors, the numbers favor the OES. The Yorkie's boldness and confidence come through more as one-owner devotion than broad social ease.

The Yorkie lives longer on paper — 11 to 15 years against the OES's 10 to 12 — and the two breeds' health risks barely overlap, sharing only hypothyroidism. The OES's remaining risks (hip dysplasia, bloat, a rare respiratory condition) are typical large-breed concerns; the Yorkie's ten-item list leans toward small-breed issues instead, like collapsing trachea and hypoglycemia. Dental disease and eye disorders round out the Yorkie's list, both common concerns in toy breeds generally.

Cost level ties at high (4/5) for both breeds, easy to miss given the size difference. The dollar ranges are close too: $110–$240 monthly for the OES against $100–$190 for the Yorkie, and $1,700–$3,200 against $1,400–$2,900 in year one. Grooming, not food, is likely doing the heavy lifting on the Yorkie's side of that number. Food costs should tilt the other way, in the Yorkie's favor, given how little a 7-lb dog eats compared to a 100-lb one.
