What is the best length of leash to buy for your dog?
A lot depends on how much control you need over your dog. For dogs that are young and you want to control their where-abouts – a good length is six feet.
The ideal choice for a first time leash is sturdy, six-foot leather; nylon or chain leash with a good quality metal clip that securely fastened to a metal ring on the collar is a practical and versatile choice for everyday use.
The six-foot length allows you to have good control over your dog.
Retractable leashes allow a pet to walk farther from his or her owner while still under some control. But there are dangers to this. A dog that is not under control can attack a person, cat, and another dog, be attacked, or run into the path of a car before the owner can "reel" him in. It is important to keep your puppy close to you during the initial days to bond, train and protect him.
Also…consider reflective materials if you expect to walk your dog at night. This will keep you and your dog visible in traffic.
