How long should a pet leash be?

Pet leash is one of the necessary items for pet families to go out for a walk, and the choice of its length is also a very important issue. How to reasonably choose the length of the pet leash?
First of all, when choosing a pet leash, the size and shape of the pet's body should be taken into account. The length of lead required for large and small dogs is different. Generally speaking, the length of the lead rope used by large dogs should be between 1.8-2.5 meters, and small dogs should be between 1.2-1.8 meters.
Second, there are environmental factors. If the area to walk the dog is relatively empty, the flow of people is less, and the vehicle is less, then the length of the lead rope can be appropriately increased to provide a greater range of activities for the pet.
However, if there are more pedestrians in the area and the road traffic is busy, it is not suitable to use too long a traction rope to avoid getting lost or dangerous.
It is also worth noting that the length of the pet leash will affect the owner's ability to control the pet, unable to timely intervene in the dog's behavior, resulting in the dog random scrambling, climbing and other behaviors, these behaviors are a safety hazard to themselves and others.
Therefore, when choosing the length of the pet leash, it should be the primary consideration to be able to control the range of activities of the pet.
In short, choosing the appropriate length of the pet leash can better protect the safety of the pet, let the owner better control the dog's action, but also let the pet have enough space to move freely. Too long or too short a lead rope will bring unnecessary risks.
The most important thing is to ensure that the dog is in the line of sight when walking the dog, and pay attention to changes in the surrounding environment at any time to reduce the probability of accidents.
