What Is The World Record For Heaviest Border Collie


Border Collies are renowned for their intelligence, agility, and herding skills, but they also come in various shapes and sizes. While most Border Collies fall within a certain weight range, there have been exceptional cases where these dogs have surpassed the average weight and set world records. In this article, we will explore the world record for the heaviest Border Collie and discuss the factors that contribute to their weight.

Understanding the Average Weight

On average, a healthy Border Collie weighs between 30 to 45 pounds (13.6 to 20.4 kilograms). However, this can vary depending on the dog’s genetics, diet, and exercise routine. It’s important for owners to monitor their Border Collie’s weight to ensure that they maintain a healthy body condition.

The World Record Holder

The current world record for the heaviest Border Collie is held by a dog named Samson, weighing in at a remarkable 97 pounds (44 kilograms). Samson, a male Border Collie, gained attention for his impressive size and gentle temperament. His owners made sure to provide him with a balanced diet, regular exercise, and frequent veterinary check-ups to ensure his overall health.

Factors Influencing Weight

Several factors can contribute to a Border Collie’s weight, often resulting in larger or heavier dogs than the average. These factors may include:


Genetics play a significant role in determining a dog’s size and weight. Some Border Collies may have genes that predispose them to be larger or heavier than others in the same breed.


A Border Collie’s diet can greatly impact their weight. Overfeeding or providing a diet rich in fatty foods can lead to excessive weight gain. Conversely, a balanced and portion-controlled diet can help maintain a healthy weight.


The level of physical activity a Border Collie engages in also affects their weight. Regular exercise helps burn calories and keeps the dog fit. Dogs with a sedentary lifestyle are more likely to gain weight.

Health Conditions

Certain health conditions, such as hypothyroidism or hormonal imbalances, can contribute to weight gain in Border Collies. Regular veterinary check-ups are essential to identify and address any underlying health issues.

Caring for a Heavier Border Collie

If you have a Border Collie that exceeds the average weight range, it’s crucial to provide them with proper care. Here are a few tips:

Diet and Nutrition

Consult with a veterinarian to create a balanced diet plan tailored to your dog’s needs. Ensure you provide appropriate portion sizes and avoid overfeeding. Incorporate high-quality dog food that supports weight management.

Exercise Routine

Develop an exercise routine that suits your dog’s abilities and health condition. Engage in activities that promote calorie burning and muscle development, such as walking, jogging, or playing fetch.

Regular Veterinary Check-ups

Regular visits to the veterinarian are essential to monitor your Border Collie’s overall health and address any underlying medical conditions that could be affecting their weight.


The world record for the heaviest Border Collie is held by Samson, weighing 97 pounds (44 kilograms). While this is significantly heavier than the average weight for a Border Collie, it is important to remember that every dog is unique. Responsible ownership, including a balanced diet, regular exercise, and veterinary care, is crucial in maintaining a healthy weight for your Border Collie, regardless of their size.
