The Quick Answer #
Where They Differ #
Health: This Is the Deciding Factor #
French Bulldogs are a medical minefield — BOAS affects nearly 100% to some degree, spine problems are common, allergies and skin issues are constant, and they can’t handle heat. Bostons are also brachycephalic but much less severely — they breathe better, handle heat better, and have fewer overall health problems. The Boston’s longer snout makes a real difference.
If you want a flat-faced dog with fewer vet bills, get the Boston.
Personality #
Frenchies are Velcro dogs who want to be touching you at all times. They’re clowns but on their own terms — trainability is limited by stubbornness. Bostons are more willing to please, more playful with strangers, and generally easier to live with. Boston energy is slightly higher — they’ll keep up on hikes where a Frenchie would need to be carried.
Cost #
This isn’t close. Frenchies cost $2,000–$8,000 to buy and $1,000–$3,000/year in vet care. Natural mating is nearly impossible — almost all are C-sections and artificial insemination. Bostons cost $800–$2,000 and have more typical veterinary costs. Over a lifetime, a Frenchie costs roughly double.
Which Should You Get? #
Get a French Bulldog if: you want the lowest possible energy, you’re obsessed with the bat-ear look, and you can afford the purchase price AND the ongoing vet bills. You work from home and can manage their health daily.
Get a Boston Terrier if: you want an apartment dog who’s healthier, more trainable, and more affordable. You’d like a dog who can join you on moderate hikes and won’t bankrupt you with vet bills.
