Suggestion: Boston Terrier Weight by Age

Measuring your Boston Terrier is easier than you think. You can weigh your dog by first weighing yourself, then picking them up and weighing again, with the difference being your dog's weight.

To measure your dog's height, you'll need a soft tape measure. Get your dog to stand still and straight, then start at the floor and measure up to their shoulders.

You can also look at your Boston Terrier's paws to estimate their size. By around 10 weeks, their paws will have grown into their adult size.
