  • Face: Both the Boston Terrier and pug have flat faces, which is why some people think they are the same. A condition known as brachycephalic gives them shortened skull bones and altered facial features. 
  • Temperament: Boston Terriers and pugs are companion animals, making them generally friendly, affectionate, and loyal. Aside from that, they can easily get along with kids, other pets, and strangers. Since they thrive on human company, they also tend to suffer from separation anxiety, leading to destructive behaviors. 
  • Fitness: As brachycephalic breeds, Boston Terriers and pugs have difficulties coping with strenuous activities because of breathing problems. However, they need exercise and walks for them to stay healthy. You can schedule longer play times with Boston Terriers because they have higher energy levels than pugs.
