Per city ordinance, when you're in public with your dog, you must always keep them on a leash and under your control. Dallas Animal Services recommends standard 6-foot leashes - a 6-foot leash attached to a properly fitted collar or harness helps you control your dog and is works well at reducing pulling.
Retractable leashes are not secure; they allow your pet to go too far from you, which puts them at risk of being hurt by a car, wild animals, or loose dogs.
Retractable leashes are not safe. For better control of your pup - and to keep both of you safe - please use a 6-foot leash! šāš¦ŗ
