If you can keep small animals, what do you want to keep?

If you want to say what is the smartest dog in the world, it is naturally a border collie. They have a strong herding instinct, are smart by nature, are good at reading words and senses, can accurately understand their master's instructions, and can drive the flock to move or rotate at a glance. The biggest feature of border collie is its intelligence, and it usually takes only five instructions to learn. Moreover, the Border Collie is the most competitive Frisbee dog breed, and it is the protagonist of the Frisbee Dog World Cup competitions over the years. This kind of dog is happy and docile. It is a good pet of the family and needs proper activities. If you have enough time to wait on him, he is also a good ornamental dog. Although he can also be cut into the shape of a lion, many people like to cut him into the shape of a lamb (the length of hair), which is very popular.
