Boston Terrier vs Yorkshire Terrier
A side-by-side comparison to help you find the right breed for your lifestyle.
Boston Terrier
Also known as: American Gentleman, Boston Bull, Boston Bull Terrier
The Boston Terrier is a compact, tuxedo-marked companion known as the 'American Gentleman' for its polite demeanor. Originally bred in Boston from English Bulldogs and White English Terriers, this breed transitioned from pit fighter to beloved family companion. They're adaptable, affectionate, and perfect for apartment living - but come with significant health considerations.

Yorkshire Terrier
Also known as: Yorkie, Yorkshire
The Yorkshire Terrier is often mischaracterized as a mere lapdog accessory. In reality, this is a **terrier** first and a companion second. While affectionate and portable, their genetic heritage as vermin exterminators in textile mills drives a personality that is tenacious, vocal, and surprisingly intense. Often called 'the Yorkie', this breed packs big-dog attitude into a tiny frame.

Boston Terrier Social Traits
None
Generally good with other dogs, some male posturing with intact males
Yorkshire Terrier Social Traits
High - naturally suspicious, early socialization required to prevent fear biting
Often reactive to larger dogs - usually fear-based, not dominance
Training
Boston Terrier
- They are sensitive - harsh corrections cause them to shut down
- Use their high food motivation to your advantage
- Be consistent - don't tolerate jumping/nipping just because they're small
Yorkshire Terrier
- Keep sessions SHORT (5 minutes max) - they bore easily
- High-value treats essential - they won't work just to please you
- Indoor pee pad system may be necessary permanent solution
Boston Terrier Considerations
Boston Terriers are extreme 'Velcro dogs' that bond intensely. Left alone for more than 4-6 hours, they develop destructive chewing, house soiling, and persistent vocalization. Not suitable if all adults work full-time away from home.
It is impossible to overstate this issue. Their brachycephalic anatomy causes them to swallow air while eating, resulting in frequent, potent gas. If flatulence repulses you rather than amuses you, this is NOT your breed.
Their shortened airways prevent efficient panting. They are at HIGH RISK of heatstroke at temperatures above 25°C (77°F). Air conditioning is a requirement, not a luxury. You cannot take them jogging or hiking in summer.
Expect loud snoring, snorting, and episodes of reverse sneezing that sound like the dog is choking. If you need silence to sleep, this breed is not for you.
Yorkshire Terrier Considerations
This is the single most cited failure mode for the breed. Due to tiny bladders and terrier stubbornness, Yorkies are notoriously difficult to housebreak. Many owners report accidents persisting well into adulthood, and some never become 100% reliable without indoor pads.
The 'watchdog' trait is hardwired. They will announce every delivery driver, neighbor, and squirrel with sharp, high-pitched barking. This can lead to neighbor complaints and eviction notices in apartments.
Yorkies often don't perceive their small size, leading to 'Napoleonic' aggression toward much larger dogs. This is usually fear-based reactivity, not actual courage, but can be dangerous.
A toddler falling on a Yorkie can kill the dog. They can be fatally injured by being dropped, stepped on, or sat upon. Not suitable for homes with young children.
Multi-Species Compatibility
| Species | Boston Terrier | Yorkshire Terrier |
|---|---|---|
| With Cats | Excellent - generally great with cats, especially if introduced young | Generally safe if raised together - but may harass a cat that runs |
| Small Mammals | Caution - may retain terrier ratting instincts with hamsters/guinea pigs | UNSAFE - the ratting instinct is alive. Dangerous to hamsters, gerbils, birds. |
| Birds / Reptiles | Caution - should not be trusted alone with free-roaming birds | Unsafe - predatory drift will trigger chase/kill |
Advanced Behavior
| Trait | Boston Terrier | Yorkshire Terrier |
|---|---|---|
| Predatory Sequence Risk | Arrested | Full |
| Biddability | High | Moderate |
| Noise Sensitivity | Low | Medium |
| Territorial Barking | ||
| Same-Sex Aggression Onset | N/A | N/A |
Boston Terrier: Predatory sequence is Eye -> Stalk -> Chase. Grab-Bite and Kill-Bite are largely inhibited, though they may still dispatch small rodents (terrier heritage).
Yorkshire Terrier: Unlike a Cavalier where the sequence is eroded, the Yorkie retains the Kill-Bite part of the sequence for small vermin. High intelligence but asks 'Why?' before 'How high?' - less eager to please than a Poodle.
First Year & Life Stages
First Year Challenges
| Challenge | Boston Terrier | Yorkshire Terrier |
|---|---|---|
| Puppy Difficulty | ||
| Destructive Phase | 6-12 | 6-12 |
| House Training | Medium | Very Hard |
| Crate Training | High | Medium |
| Adolescent Regression |
Boston Terrier: Housetraining can be challenging due to small bladders and dislike of cold/wet weather. They're not destructive chewers by nature - main challenge is potty training.
Yorkshire Terrier: Unlike larger breeds, you cannot simply 'crate and wait' - their bladders are too small. Expect accidents for the first year. The combination of extreme fragility, house training difficulty, and hypoglycemia risks makes Yorkie puppies very demanding.

Boston Terrier Quirks
The Gas Factory
Expect frequent, potent flatulence due to swallowing air while eating. Slow-feeders and probiotics help reduce but never eliminate.
Reverse Sneezing
A spasm of the soft palate that sounds like a terrifying asthma attack. Usually harmless - gently massage throat to stop it.
The Sunbather
They LOVE to bake in sun patches, but must be supervised to prevent heatstroke. Their heat regulation is poor.
The Burrower
They love to sleep under blankets and will burrow into bedding. Perfect for cold nights, concerning for hot ones.
Yorkshire Terrier Quirks
Reverse Sneezing
A spasm of the throat/soft palate that sounds like a goose honking. Scary for owners but usually harmless.
The Yorkie Shake
Will violently shake toys - this is the motor pattern for breaking a rat's neck, their genetic heritage
Weather Diva
Often refuses to go outside in rain or cold - may require indoor pee pad system year-round
Velcro Mode
Will follow you to the bathroom, sit on your feet while you cook, and attempt to sleep on your head
