The teacup Boston Terrier is uncommon among breeders. The standard weight for the Boston Terrier is 12 to 25 pounds. They need to weigh less than 5 pounds to qualify as teacup dogs. Teacup Terriers are rare and are the result of cross-breeding.
Have you heard of teacup dogs? They are the smallest types of dogs, weighing less than 5 pounds.
While some dogs do reach this requirement, the Boston Terrier rarely does. But they can.
This article explores the ways teacup Boston Terriers come to be. It also offers an overview of four Boston Terrier mix breeds that can result in a teacup Boston Terrier.
What is a Teacup Dog?
A teacup dog is a dog that weighs 5 pounds or less. The term “teacup” refers to dogs so small that they fit into a teacup. Teacup dogs are smaller versions of regular breeds. The most common teacup breeds include Pomeranians, Chihuahuas, Poodles, and more.

Teacup dogs are preferred by a wide variety of owners. Either due to their cute size or low needs.
The maintenance of teacup dogs is perceived as less than the one for regular-sized dogs.
Teacup dogs are easy to carry around on any means of transportation. They make great companions for restaurants or coffee shops because they easily fit in a bag.
Teacup Boston Terrier vs. Mini Boston Terrier
Teacup Boston Terriers are smaller than mini Boston Terriers. Teacup versions weigh less than 5 pounds, while mini Boston Terriers weigh between 5 and 12 pounds.
The difference between a teacup dog and a mini dog is the size. Teacup dogs are smaller than minis. Both are smaller than a standard Boston Terrier
Mini Boston Terriers can qualify as teacup Boston Terriers, but not the other way around.
The standard measurements for Boston Terriers:
- Height: 15–17 inches
- Weigh: 12–25 pounds
Miniature Boston terriers measure less than standard Boston Terriers but are not always small enough to qualify as teacup dogs.

How Do You Get a Teacup Boston Terrier?
There are two ways of getting a teacup Boston Terrier:
- By breeding two small Boston Terriers until you get a teacup Boston.
- By crossbreeding Boston Terriers with other teacup breeds.

Getting a Teacup Boston Terrier by Mating Two Small Bostons
To breed a teacup Boston Terrier, breeders need to pair two of their smallest dogs and hope for the best. There is no guarantee the offspring will be teacup-sized. If they are, they will be bred again with another miniature Boston terrier, and so on.
This breeding method is rarely used by breeders. It leads to the propagation of several health issues the initial parents pass on to their offspring.[1]
Boston Terriers that weigh 5 pounds or less are usually so small because of various health issues, including dwarfism.
Teacup and mini Boston Terriers bred using this method can suffer from many health issues:
- Hypoglycemia
- Heart defects
- Collapsed trachea
- Blindness
- Patellar luxation
- Seizures
- Liver shunts
- Respiratory issues
- Digestive problems
Crossbreeding a Regular-sized Boston Terrier and a Teacup Dog
By breeding a regular Boston Terrier with a teacup dog, breeders often get a mini Boston Terrier instead of a teacup Boston. If they are lucky, the puppies are teacup-sized when they become adults. Still, there is no guarantee.
Mixing regular-sized Boston Terriers with teacup dogs is safer than breeding unhealthy teacup-sized dogs.
During this type of cross-breeding, the father is a teacup and the mother is a regular Boston Terrier.
Otherwise, the risk of death during or at birth is too high for the female.
