Deep dive
Size and build
The Mastiff outweighs the Corgi by an enormous margin, 120-250 lbs against just 24-30 lbs, a gap that can run past eight times at the low end and closer to ten at the high end. Height tells a similar story: 27-32 inches for the Mastiff, just 10-12 for the low-slung Corgi. Few comparisons pair a giant breed with a dog this short.
Energy and exercise
The Corgi is considerably more active, exercise need high (4/5) against the Mastiff's low (2/5), and energy level high (4/5) versus the Mastiff's low (2/5). Corgis were bred to herd cattle all day and that drive is very much intact; the Mastiff, despite its size, is the more sedentary of the two by a clear margin.
Grooming and shedding
Grooming favors the Mastiff, low (2/5) against the Corgi's moderate (3/5). Shedding runs the other way and by more: Corgi high (4/5), Mastiff moderate (3/5), that double coat blows out seasonally and is famous among Corgi owners for the amount of fur it produces relative to the dog's small frame and low grooming score.
Apartment living, noise and time alone
The Corgi barks more, high (4/5) against the Mastiff's very low (1/5), its herding instincts show up as vocal alerting at passersby. Apartment suitability actually favors the Corgi, high (4/5) against the Mastiff's low (2/5), despite its higher exercise need, a testament to how much size alone drives that score.
Training and owner experience
The Corgi trains more easily, high (4/5) against the Mastiff's moderate (3/5), and suits first-time owners a bit better too, moderate (3/5) versus the Mastiff's low (2/5). Neither score for the Mastiff is bad exactly, just consistently behind a genuinely easy-to-train breed built for working alongside a handler.
Kids, other dogs and visitors
The Mastiff edges ahead with kids, very high (5/5) against the Corgi's high (4/5), and the Corgi pulls ahead with other dogs, high (4/5) against the Mastiff's moderate (3/5). Friendliness to strangers ties at moderate (3/5) for both, so neither stands out as unusually outgoing or reserved.
Health and lifespan
The Corgi outlives the Mastiff by two years at minimum, 11-13 versus 9-11. Three conditions overlap, hip dysplasia, progressive retinal atrophy, and hypothyroidism, and the Corgi's list is notably long, ten conditions including intervertebral disc disease and degenerative myelopathy, both linked to its long back and short legs. The Corgi's health list is actually longer than the giant breed's here.
Cost to keep
The Mastiff costs more to keep, very high (5/5) against the Corgi's still-substantial high (4/5), and the numbers confirm it: $150-350 monthly versus $100-200, and $2,200-4,500 against $1,500-3,000 in year one. The Corgi isn't a cheap breed either, just meaningfully less expensive than the giant across every category.
