While life expectancy varies dog to dog, there are a few things you can do as a dog owner to help prolong their lifespan & increase their quality of life.

Read on to learn everything you need to know about the Boston Terrier’s lifespan, ways of prolonging it, and common causes of death.

What is the lifespan of a Boston Terrier?

The average lifespan of a Boston Terrier is between 13 – 15 years.

5 Boston Terrier Lifespan Factors

There are several factors that affect a Boston Terrier’s lifespan.

These include genetics, preexisting health conditions,environmental factors, and diet…

1. Genetics

A Boston Terrier’s lifespan is heavily dependent on their genetics.

If a dog has a short-lived parent, he will likely have a shorter life.

However, if both parents are long-lived, their offspring will probably live longer than expected.

It is essential to know your dog’s lineage and find out how long its parents lived to get an idea of how long your dog might live.

Note: When adopting/rescuing a Boston Terrier, you might not have as much insight into their parents’ health as you would when buying one from a breeder.

2. Health Conditions

Health conditions can also affect a Boston Terrier’s lifespan.

Dogs with health conditions may not be able to enjoy a full lifespan because of their condition.

Some conditions may also prevent your dog from living the healthiest lifestyle. For example, dogs with hip dysplasia often develop osteoarthritis later in life, which can cause pain and stiffness when walking or running.

Some dogs may not be able to walk when they develop osteoarthritis, so it is vital to take them to see a vet if you notice any signs of stiffness or pain when walking or running.

3. Environmental Factors

Environmental factors can also affect a dog’s lifespan.

One environmental factor that affects a dog’s lifespan is the weather.

Extreme heat or cold can make your dog sick, especially if they are old or have health issues.

It is vital to keep your dog inside during extreme weather events so that they do not get sick from being outside in hot temperatures for too long.

4. Lack of Proper Care

Neglect can shorten a dog’s lifespan.

Dogs need exercise and at least one meal a day if they are not left alone for long periods.

Not giving your dog enough attention or feeding them a good diet can shorten their life considerably.

If you do not feel like taking care of your dog, it is best to rehome them with someone who will give them love and attention so they can live longer.

5. Diet and exercise

A Boston Terrier’s diet and exercise routine can also affect its lifespan.

Giving your dog enough food is essential, so they do not get hungry, but not too much, so they gain weight.

If you feed your dog more than necessary, they may have trouble losing weight when it becomes essential because of overeating.

Exercise is just as important as a healthy diet to maintain a good weight.

However, if your dog has health issues or cannot move around easily due to arthritis or other conditions, it is okay for them to be sedentary as long as they eat a healthy diet.
