French Bulldog vs Boston Terrier Dog Comparison

French Bulldog vs Boston Terrier Dog Comparison

These little dogs look very similar but there are differences in the two breeds. Both have a common ancester, the English Bulldog, which explains why they are the same size.

Here I will take a look and hopefully learn so I can tell which one is which!

French Bulldog vs Boston Terrier

ears upright with rounded tips

French Bulldog vs Boston Terrier


Boston Terrier

Origins  America, A cross between an English Bulldog and English Terrier

Appearance  Long legged, muscular, small boned, athletic

flat cheeks, no wrinkles

Lifespan 13 – 15 years

Temperament Loyal, friendly, playful, alert, energetic, expressive and intelligent.

Tuxedo type markings.

Health Their large eyes make them prone to Corneal ulcers.

They are prone to flatulence.

Whelping can be complicated and small litters very common.




They don’t shed much, and are easy to groom.

They are both good with children and other dogs.

The short muzzle and brachycephalic face of both breeds means that they may suffer from problems with their respiration, including snoring,

Both are prone to overheating.

Both rarely bark without cause.

They can both be a little stubborn.

Both have a mischievous personality.



The Boston is more active and playful, the French Bulldog is more sedentary and is more laid back.

The French Bulldog can become overweight because they don’t tend to be as active as the Boston Terrier.

Boston Terriers can swim, Frenchies struggle to swim because of their physique.

If the dog is black and white it is most likely to be a Boston Terrier, French Bulldogs are more likely to be just one colour.

So, in a nutshell, Bostons are taller, with unwrinkled skin, smaller ears and are more athletic of the two.

All this information was researched from established dog breed sites, I don’t know of any personally , but maybe one day!

If you do own either breed, let me know how they measure up to these stats, I’m very interested to know.
