Increases in walking speed dramatically raise calorie burn per mile as well as per minute. Indeed, at about 12:30 per mile, walking hits a point where it burns about the same calories/mile as running. Walk faster than 12:30 and you will burn more calories/mile than running at 10:00 pace.
Like Boston Terriers in general, they have sensitive digesture systems and they can get some health issues, including cataracts, cherry eye, allergies, deafness, and luxating patellas. The Red Boston Terrier is probably the most popular color that is out of the Boston Terrier norm.
Boston Terriers, being a small breed, have an average lifespan of 12-14 years. And with 12-14 years being the average, it goes without saying that there are those individuals that outlive the projected life expectancy and those who fall short of reaching it.
