I like 4 or 6 foot leashes personally, I always go for those ones when walking dogs at the shelters. We own a few different retractable leashes at the house and they are OK, but I've gotten hurt with them, and so has my mum, and there's been some "incidences". I find that a good four foot leash is best for keeping dog at safe distance by side when walking on road and in public areas.

Pros: safe length

Cons: none

i like the 4 and 6 ft. leashes because when you want your dog to stay away from another dog then you dont have to deal with a leash line and pushing all kinds of buttons to pull it back.

Pros: keeps your dog close to you.

Cons: hurts your fingers.

everyone should have one of these.

Pros: great length

Cons: none

No dog should be walking 6 ft in front of you.
Four feet is best to keep you dog by your SIDE!!

Pros: use 4 foot more often

Cons: 6 foot a little too long

This is a great product. The shorter one can be helpful when training to heel. The longer one is also nice for training, especially come and stay. Or, use them for taking a nice stroll!

Pros: Different sizes

Cons: none
