Border Collie Growth FAQs

What is the usual size of border collies?

Border collies are known to be medium-sized athletic types of dogs. It won’t be easy for them to live in an apartment comfortably for their size. Plus, since they are athletic dogs with very high energy levels, they would need plenty of exercise and playtime every day.

Hence, having a border collie will be better in a more spacious place with fur parents who can spare some time for adequate exercise.

How big are female and male border collies will be?

Female border collies are typically smaller than males, but in some cases, females can go bigger than males. Female border collies usually grow at a maximum size between 40 to 50 centimeters or 20 inches. Females typically have long legs and a slightly thinner body than males, so it’s no surprise why they weigh less too.

Can I determine my border collie’s physical growth through its paw size?

Your doggo’s paw size can’t be a precise basis of how big or small your border collie will be. But, there is a common connection between their paw size and your doggo’s expected physical maturity.

That is because heavier dogs will have broader and sturdier paws to support all their weight. However, this should not be a way to exactly conclude how big or small your border collie is by simply looking at their paw size.

Can border collies experience rapid growth?

Yes, border collies can experience rapid growth in their first three to ten months. This is called a growth spurt. After ten months, they will continue growing but at a much slower pace. In a period of rapid growth, it’s essential to give them enough rest and discourage too many exercises.
