I want to give my dog some freedom
Thats nice but what exactly do you mean by giving your dog freedom?
I'm a firm believer that a dog should be allowed to do as he pleases.
Freedom is relative when it comes to pets. You shouldn't let a dog just run free. It could get run over by a car or hurt by someone.
So I should walk my dog on a leash?
Walking your dog on a leash would be wise. Often dogs can become distracted by things out in the wild and my run off in a hurry. Leashes can prevent dogs from doing this and ensure they're by your side and safe.
