slip leashes are the best for moving a dog short distances or providing a leash for the owner who forgot one. We had a couple of these for our own dog for when we travelled in the car - quick way to get him out for a potty break without having to mess with collars and snap leash

Pros: useful

Cons: not for everyday use

I prefer the slip leashes when I walk a dog. It depends on how strong your leash is whether it will work for the stronger dogs.

Pros: easy to put on

Cons: may not be strong enough for the big guys

We used to regularly use slip leads to walk the dogs inside the building, and many eons ago we even would double-leash with them to walk the dogs outside. They're a great tool for going a short distance such as from the kennel to clinic, but they don't really work well as a regular leash. For dogs larger than about 25 pounds, you don't really have much control with a slip leash, and it's much harder to maintain a six foot distance when dogs are straining to check each other out (either in a positive OR negative way). We also had several instances of dogs managing to get away from people outside.

Overall, slip leads are a great make-shift leash for clinics and kennels where the dogs are almost always in a controlled area. However, they're definitely not as sturdy as a standard leash, so you should use caution that the dog doesn't get away.

Pros: Cheap, difficult for dog to slip out of

Cons: Difficult to maintain control over larger, stronger dogs, can be pulled out of hands without much effort

great for taking dogs out for a quick potty at the shelter. They are always indoors (no need to go outside to the run), so I'm comfortable using it. Easy to use, tons of colors, and lasts forever. They even sit in bleach cleaning solutions and still last. Not for large dogs that are pullers as they have little control and the leash is quite short.

Pros: lasts forever

Cons: not very sturdy

These little leash/collar combos are ok for quick jots to the potty runs in the shelter, but I don't trust them for anything requiring any kind of security. Even though they will tighten up if a dog tries to back out of them, it is not very hard for a dog to finagle its way out of one.

Pros: quick and easy to put together

Cons: not too hard for dogs to slip out of
