Why You Need To Maintain a Healthy Weight for Your Boston Terrier

If your Boston Terrier becomes overweight, he could develop various health problems. These problems include the following:

  • Diabetes
  • Heart disease
  • High blood pressure
  • Cancer
  • Arthritis

Obesity can cause pain and limited mobility, making it harder for your Boston Terrier to get around and play. You may also notice more complications with his brachycephaly as he has difficulty breathing from the excess weight. 

Ultimately, obesity can even lead to a decrease in his life expectancy. Your veterinarian can tell you the ideal weight for your dog’s size, but it’s up to you as his owner to ensure he maintains it. 

Some signs to look for when monitoring for obesity are an inability to feel the ribs and no longer being able to see the waist. You may also find your dog has a larger belly and is reluctant to do the things he used to do or tires more quickly.

How To Maintain a Healthy Weight for Your Boston Terrier

You can take several steps to prevent your Boston Terrier from becoming overweight or correct an obesity problem. 

First, ensure you have a solid exercise plan in place. You need to walk your Boston Terrier daily. He may also need extra playtime in the yard. If your dog is already overweight, introduce additional activity slowly and on cooler days to avoid the possibility of heat stroke.

Second, portion out the food. It’s best to feed an adult Boston Terrier twice a day. Free feeding is not a good idea because your dog can overeat and quickly become overweight. Ensure you measure the food when you serve it. You may find that you’ve been providing too much food all along when you start measuring it.

Third, avoid high-calorie treats. Anything more than 5 to 10 calories per treat is too high. While they may be tiny, they add up quickly. For one little treat, some commercially prepared treats are as high as 50 calories. Now imagine if you gave your dog several of those. Consider offering some fruits and vegetables that are low in calories as an option. As strange as it may sound, dogs do enjoy eating them.

Most importantly, don’t offer your dog any table scraps. There are many reasons you shouldn’t do this, but the food we eat can cause significant weight gain in Boston Terriers. The daily calorie intake for your Boston Terrier is only a maximum of 500 calories, but one slice of cheese can have 100 calories, so you can easily see the problem with feeding table scraps. This practice is a leading cause of pet obesity in this country.

Final Thoughts

Boston Terriers are fantastic, compact little dogs that make great companions. They are the perfect size for many situations, offering many people the ideal option for dog ownership. Because of their small stature, they make excellent cuddlers and lap dogs. 

Boston Terriers are at most 25 pounds fully grown. They stand 16 to 18 inches at the shoulder. The breed is considered small by the American Kennel Club. Because of their size, they make excellent companions that can live in nearly any situation.

You must maintain a healthy weight for your Boston Terrier as he is susceptible to becoming overweight. Following a healthy diet and exercise routine will ensure that he lives a long, healthy, and happy life, keeping you company for years to come.
