Once upon a time, choosing a collar and leash for your pooch was a straightforward endeavor. Leash and collar designs were pretty standard, and options were limited. Today, while it might be an exaggeration to say there are as many leash and collar options as there are different kinds of dogs, it's not much of one — the choices can be overwhelming. Use this guide to help you sort through the different types of dog collars, leashes and harnesses that best fit your pup's needs.
What Type of Leash or Collar Is Best for My Dog?
There are different types of dog collars, leashes and harnesses for a wide variety of needs. While a standard leash and collar combination works great for walking a well-behaved, medium-sized dog with low-to-moderate energy levels, other dogs may do better with more specialized gear.
Small Dogs
Small and toy breed dogs tend to be delicate, and standard collars run the risk of crushing their trachea or injuring their necks. For your little pooch, it's best to use a shoulder harness that doesn't place pressure on the neck or throat. Harnesses have the added advantage of being difficult for tiny pups to slip out of, says Daily Puppy. Look for a harness that fits snugly enough that your dog can't wiggle out of it without it being uncomfortably tight.
A lightweight retractable leash will provide you with the most options, allowing your little pupper to safely venture a little further away from you while giving you a way to gently reel them back in without jerking them or having them get tangled up in the leash.
Large Dogs
On the other hand, large and giant breed dogs generally do well with thick, heavy-duty collars that can be easily put on and removed and that won't break easily. Look for a durable material like leather or woven nylon that fits tightly enough so that your dog's head can't slip out. You should still be able to fit two fingers between the collar and your dog's neck to make sure it's not too tight. Be sure to inspect the collar regularly for wear and tear and replace it when it starts to wear out to prevent a break and a surprise escape.
Like their collars, big dogs need heavy-duty leashes. A thick, durable standard leash made of leather or woven nylon (or a chain leash if your big pup tends to chew) is a good match for your dog's size or strength. Go for a longer lead for walks in the park or country, and a shorter one for busy city streets. An adjustable-length leash can provide you with more versatility and prevent you from having to buy different leashes for different occasions.

Dogs that Pull
For anxious, easily distracted or high-energy dogs who try to pull you around with them, a front-clip harness works well to contain this impulse. Standard harnesses are based on the same design used by sled dogs and actually encourage pulling, says Petful. Harnesses that allow you to clip the leash to the front apply extra pressure to the chest, which provides a cue for your pup to slow down.
Both of the above harnesses work well with a standard leash suited to the size and weight of your pooch. Avoid using a retractable leash, which tends to encourage pulling rather than discourage it. The right leash will also help in training them not to pull.
