Boston Terrier 
"If you choose a Boston to become the newest part of your family, get ready for a new best friend for many, many years. Depending on the breeding, health and how well your dog is taken care of, a Boston Terrier can easily live between 12 and 14 years old."
Boston Terriers are perfect for individuals looking for a sociable, loving and gentle dog. These dogs love attention of people and are an adorable addition to any family. They get along well with other dogs and even cats. Not to mention they are highly intelligent and pick up on tricks with ease.
The Boston Terrier is an indoor dog and although it likes to play outside it should not be left outside for long periods of time. There are also certain environments that it may not do well due to its physical build and its personality. Due to its social nature the Boston Terrier does not like to be left alone for long periods of time. It is also a very trusting dog and could easily be persuaded to walk off with a stranger, as it does not bark unnecessarily.
A well-socialized Boston Terrier will get along with everyone in your household and barks only when it senses danger or intruders. The high intelligence of a Boston Terrier allows it to differentiate between friends of the family who are welcome in the house and people who are clearly intruding. This is in part due to the sensitivity of Boston Terriers to their owner's moods. They are especially sensitive to the tone of your voice and can instantly sense a rebuke in your voice.
If you want to be certain what you are getting into, consider buying or adopting a retired Boston Terrier breeder instead of a puppy. This way you know what you are getting into without the troubles of a puppy. You can judge from an adult Boston Terrier right away what type of dog you have on your hands.
