Both breeds are small, but not identical. The Griffon runs 8 to 12 pounds and 7 to 10 inches, while the Cavalier is a bit larger and taller at 13 to 18 pounds and 12 to 13 inches. Neither will overwhelm a small home, but if you want the more substantial-feeling lapdog, the Cavalier's extra weight puts it there. Think of the difference as one size class within small, not a leap between classes.
The Griffon needs less daily activity, rating 2 out of 5 against the Cavalier's 3. In practice that's the difference between a couple of short walks and a slightly longer outing plus some play. Both breeds' overall energy level ties at moderate (3/5), so day to day they feel fairly similar once you're past the length of the walk.
Grooming needs tie at a moderate 3 out of 5 for both, the Griffon's wiry coat and the Cavalier's silky, feathered coat each need regular brushing. Shedding is where they split: the Griffon rates low (2/5) and the Cavalier moderate (3/5), so expect more hair around the house with the Cavalier despite the similar overall grooming workload.
Both breeds score a perfect 5 out of 5 for apartment suitability, so space isn't the deciding factor between them. Barking leans toward the Griffon being the noisier of the two, moderate (3/5) versus the Cavalier's low (2/5), while neither dog handles solo time well. The Cavalier actually scores lower on tolerating being alone, a 1 out of 5 against the Griffon's 2.
The Cavalier is the more forgiving choice for a new owner, rating 5 out of 5 for first-time suitability against the Griffon's 3, and it trains a notch more easily too, 4 versus 3. Neither breed is genuinely difficult, but if this is your first dog, the numbers favor the Cavalier's easygoing, people-pleasing nature. Both breeds are sensitive, though, and respond better to patience than to correction-heavy methods.
The Cavalier outperforms the Griffon across the board here: very high with kids (5 vs 3), very high with other dogs (5 vs 3), and high with strangers (4 vs 3). If your household includes small children, other pets, or frequent guests, the Cavalier's easier social profile is the more predictable bet on paper, even though individual dogs always vary.
Both breeds average 12 to 15 years, so lifespan isn't a differentiator here. Their health lists overlap more than most pairings: hip dysplasia, patellar luxation, and syringomyelia appear for both. The Cavalier carries a serious additional concern, myxomatous mitral valve disease and heart murmurs are common enough that cardiac screening matters. The Griffon's added risk is brachycephalic airway syndrome from its flat face.
The Griffon is the cheaper dog to keep: $80 to $150 a month versus $100 to $200 for the Cavalier, and $1,100 to $2,300 in year one versus $1,500 to $3,000. The gap isn't huge, but the Cavalier's higher-maintenance coat and its heart-screening needs account for most of the difference over a full year of ownership.
