Because many dogs have relatively long mouths. Border Collies often have a U-shaped mouth, and their mouths are also more rounded.
Ears
Most of the Border Collie’s ears are semi-erected, which means that if the dog recommended to you by a merchant has drooping or fully erect ears, you may want to pay attention.
Of course, we cannot make direct conclusions based on our ears alone. We must also consider other characteristics. After all, dogs are the same as people, but they also look different. The Border Collie's ears cannot be fully established when they are just born, but they will improve when they grow up.
Body shape and pattern
It is recommended that parents choose the dog they like based on size and pattern. This does not mean that it is easier to decide the breed of dog. This is because most people keep dogs for fun or companionship, so choosing a Border Collie with a personality that matches yours is more important than choosing just one breed.

Eyes
