What Influences a Terrier’s Weight?

A small Terrier can weigh up to 12 pounds, whereas some can grow as heavy as 75 pounds. However, there are several factors that influence a Terrier’s size and weight. While some are natural causes, others are within your control.


Several generations of a particular Terrier would have an ideal height and weight. This is why the weight range or proportioned weight of various Terrier types would also differ. However, this may also depend on whether you have a full-blood or mixed pet.


Dogs need a proper diet to stay in shape and have a healthy lifestyle. Diet and nutrition are among the things you can easily control when monitoring a Terrier’s weight.

  • Consider the calories: You should also consider the specific calorie needs of your pet per day. Insufficient or too many calories may either lead to being underweight or obese.
  • Add supplements: If your Terrier is a picky eater, schedule a checkup with a veterinarian so you can get a prescription for supplements. You’ll usually need to include vitamins for your Terrier’s diet, especially if you’re mostly feeding it homemade meals.
  • Follow a meal plan: Schedule meal times so you can avoid over or underfeeding your Terrier. Setting a meal plan and time also lets you balance dry or wet dog food, organic treats, rice, and even vegetables.

As long as you feed your Terrier with the right kind of food in intervals, you may help retain your pet’s weight in its breed’s average range.


Age can influence calorie imbalance in Terriers. As Terriers grow old, some of them may not have agile bodies. In some cases, senior dogs also eat less, changing their weight over time.

Even young ones tend to minimize their activities, which sometimes depends on the owner. If your Terrier gets used to sprawling on the sofa all afternoon or morning because you’re not taking it out for a walk, it may eventually not like to do other physical activities.


Terriers are full of energy, especially American Pitbull and Boston Terriers. Encouraging them to move while ensuring proper rest can help control your pet’s weight.

  • Set an exercise routine: While Terriers are not necessarily hyper, some can be more energetic than usual, especially young ones. Get your Terrier to exercise at least 60 minutes per day to control weight and avoid pent-up energy. You can do this by combining walking and running.
  • Provide mental stimulation: Some senior Terriers may not have the power or strength to run or do obstacle games. Using puzzle games, interactive toys, and treat balls are great ways to keep a Terrier’s weight in check.
  • Ensure adequate rest: Rest is an important part of a Terrier’s routine. While Terriers have high energy levels, they are also among the sleepiest pets. They may sleep for 10 to 14 hours a day, so ensure that their waking hours consist of eating, playing, and interacting with people.

Living Space

Whether it’s a 15-pound Border Terrier or a 50-pound American Pitbull Terrier, having less space to move around may prevent it from achieving the ideal weight.

If you need to keep your Terrier in a crate or playpen when you’re at work or having a baby, make sure that the size is big enough to encourage movement. When a Terrier only gets to sleep and eat in a living space, it may suffer from weight and mobility issues and challenges.

How Will I Know if My Terrier Has the Right Weight?

While you know that small Terriers may weigh around 12 to 35 pounds, and bigger ones can reach up to 75 pounds, it can still be quite tricky to determine if your Terrier has a healthy weight.

You can ensure this during your vet visits. However, it’s also helpful to do regular visual assessments.

  • A Terrier with the average weight should have a waist that subtly curves inwards. If it’s bigger or smaller than that, you may need to plan a change in diet.
  • Check your Terrier’s side profile. A healthy Terrier’s abdomen should slope slightly upward from the rib cage.
  • Touch your Terrier’s rib cage area. Your pet has the right weight if you can feel its ribcage yet not see the bones bulging through the skin. An underweight Terrier would have a visible rib cage, whereas you won’t feel the ribcage in an overweight dog.
  • Unlike Boston Terriers with short, smooth coats, other breeds like Yorkshire Terriers have longer fur. In such cases, swipe your finger along your pet’s spine to check the pelvic bone. Underweight Terriers would have a protruding pelvic bone, while healthy ones should have a thin layer of fat between the bones and skin.
