The retractable dog collar also emphasizes safety design. Many styles are equipped with safety devices such as reflective strips or LED lights, which can alert others to the presence of pet dogs at night or in low light environments, reducing the risk of accidents. At the same time, some high-end styles are also equipped with smart chips or GPS positioning functions to help owners better track and manage the whereabouts of their pet dogs.

The material selection of the stretchable dog collar is also very meticulous. Usually made of soft and durable materials such as nylon or rubber, these materials not only have good elasticity but also can resist wear and tear, ensuring the durability of the collar. Meanwhile, these materials are also relatively lightweight and will not cause too much burden on pet dogs.
