French Bulldogs and Pugs are small, affectionate, flat-faced companion dogs that suit apartments and need little exercise. They also share the same serious problem: their short faces make breathing harder, especially in Australian heat. The Frenchie is heavier and more muscular; the Pug is smaller and more prone to weight gain and eye injuries. Whichever you choose, how open the puppy’s nostrils are matters more than the breed.

Figures come from our breed profiles of the French Bulldog and Pug, where each one is explained and sourced. Costs are estimates in Australian dollars: the first year includes buying the puppy; yearly costs cover food, grooming and routine vet care; lifetime is our standard estimate. Ratings are ThinkPets ratings (how we rate).
Choose a French Bulldog if…
- You want a small but sturdy dog, usually 8 to 14 kg.
- You live in an apartment and want a dog that needs about 30 minutes of gentle exercise a day.
- You’re prepared for vet costs: breathing, spine and skin problems are common in the breed.
- You can keep it cool in summer, with air-conditioning on hot days.
Choose a Pug if…
- You want a smaller, lighter dog, usually 6 to 8 kg.
- You’d like slightly lower costs: Pugs come out a little cheaper in our estimates.
- You’re strict about food. Pugs gain weight easily, and extra weight makes their breathing worse.
- You’ll keep an eye on their prominent eyes, which are easily injured.
The health problem both share
Both breeds are prone to brachycephalic obstructive airway syndrome (BOAS): normal soft tissue squeezed into a shortened skull. Research has found narrow nostrils to be the strongest visible warning sign, and extra weight independently raises the risk. Real-world life expectancy reflects this. In a 2022 UK study of more than 30,000 dogs that died between 2016 and 2020, life expectancy at birth was about 7.7 years for Pugs and 4.5 years for French Bulldogs, against 11.2 years for all dogs. The authors noted the French Bulldog figure is pulled down by how young the breed’s population is, but both breeds’ health problems are real. Our French Bulldog and Pug profiles explain how to assess a puppy.
Before you buy either
- Look at the nostrils: open, or pinched to slits?
- Listen to the puppy at rest and after two minutes of play. Snorting and snoring at rest are signs of a dog struggling to breathe.
- Ask whether the parents have had breathing assessments, and whether either has needed airway surgery.
- Plan for heat: both breeds overheat quickly, and Australian summers are a real danger.
Quick answers
Which is healthier, a French Bulldog or a Pug?
Neither is a healthy choice by default. Both have breathing problems from their short faces, and both are prone to spine problems. Pugs are also more prone to eye injuries and weight gain. A puppy with open nostrils from health-checked parents matters more than the breed.
Which is better for an apartment?
Both suit apartments well. They’re small, need little exercise and are happy indoors, as long as the home stays cool in summer.
Which costs more?
A French Bulldog costs a little more in our estimates, both up front and each year. Either can cost much more if it needs airway surgery or spinal treatment.
Which is easier to train?
They’re similar: both are rated 3 out of 5 and can be stubborn. Short, reward-based sessions work best.
Do they shed?
Yes. Both have short coats that shed moderately all year. Their face folds also need regular cleaning to prevent skin infections.
