Harnesses are considered to be safer for walking dogs who pull on the leash, as they reduce the pressure on the throat. This is particularly important for smaller dogs (who are more fragile), puppies, and dogs who pull hard enough to cough and wheeze. There are many styles of harnesses on the market - here is a guide with lots of examples.
TIP: Make sure to measure your dog before purchasing a harness, so that you know which size to get. Measure the circumference around your dog’s rib cage with a tape measure, or with string that you then compare to a ruler.
Traditional or “back clip” harnesses
With these, you attach the leash over the dog’s back, and they spread the pressure from a tight leash across the dog’s chest. This reduces potential injury and makes it more comfortable for the dog when he pulls. For this reason, you may hear that harnesses “encourage” pulling. That’s not actually true - you can still implement leash walking training to teach your dog to walk nicely.
You can divide “back clip” harnesses into three types, depending on how they are placed onto the dog’s body.
Over the head - Note that many of these don’t work well for dogs with disproportionately large heads, like bulldogs. Good for dogs who don’t mind sticking their heads through, and don’t like their feet being picked up.
Red Dingo Classic Nylon Back Clip Dog Harness - Classic “H-style” harness with thin straps.
RuffWear Front Range Dog Harness - Similar to the above, but with wider, padded straps.
Puppia Polyester Back Clip Dog Harness - Common style of mesh or fabric harness. Requires you to lift one of the dog’s paws up.
Julius-K9 IDC Powerharness - This one has a very wide opening for the head, so would be fine for bulldogs, or dogs who are more sensitive to things coming over their heads.
Step in - No worries about the size of your dog’s head, but do require you to pick up their feet or train them to step in.
Frisco Nylon Step In Back Clip Dog Harness - Some people find the thin straps difficult to orient and get buckled around their dog, but the large leg holes may be helpful.
Best Pet Supplies Voyager Black Trim Mesh Dog Harness - In my experience, this style with wider fabric tends to be easier for people to figure out, but the leg holes are smaller.
HUGO & HUDSON Easy V Dog Harness - Easy to put on, but less secure and doesn’t spread pressure out as effectively.
Buckled/velcroed on without having to slip over head or legs - these are the best choice for dog that are sensitive to body handling.
Blue-9 Balance Harness - Unlike most “H-style” harnesses, it has a buckle for the straps that go around the neck - no need to pull over the head
Mighty Paw Sport Harness 2.0 - This harness has a buckle for the straps around the neck, wider straps to make it more comfortable, and a handle on the back for extra control. I like this one a lot.
Clean Run Perfect Fit Modular Fleece-Lined Harness - The ultimate customized body harness for any shape of dog.
Bark Appeal Wrap N Go Harness - Velcro vest for small dogs only; very easy to put on and take off for people who struggle with plastic buckles and straps, or for dogs who don’t tolerate body handling.
spoileddogdesigns Air Mesh Wrap Dog Vest Harness - Same as above.
Front clip or “no pull” harnesses
With these harnesses, you attach the leash in front of the dog’s sternum*, which turns the dog toward the side when he pulls. This gives the walker a mechanical advantage when slowing the dog down or turning to the side. Therefore, it is easier to keep control over the dog and implement leash walking training.
*Some people like to use a double-ended leash and attach it both the back and the front of a no pull harness, as they feel that this gives them even more control.
Freedom No-Pull Harness by 2 Hounds Design - This is my very favorite harness, with one caveat - I find that their older style with solid-colored nylon straps is more secure than the newer versions with “EarthStyle” recycled plastic straps (which tend to loosen with time). I find that this brand fits the highest variety of dog body types, while being quick to put on and take off, and look cute!
“Tactical” style harnesses such as these provide the mechanical advantage of a front clip harness, but are much more “escape proof” for wiggly pooches.
I do not recommend the following “no pull” harnesses:
PetSafe Easy Walk Dog Harness - The front slides around too much and too many dogs get bald or sore spots behind their armpits.
Ones with wide, padded fronts and thinner straps over the back, such as the Frisco Padded Nylon No Pull Dog Harness - they slide around on the dog’s body too much to be useful.
PetSafe 3-in-1 Reflective Dog Harness - Same as above, slides around on the dog’s body too much.
Sporn Mesh No Pull Dog Harness - Doesn’t have the mechanical advantage of a front clip, and is supposed to work by tightening up behind the dog’s armpits, but in my experience that rarely works.
Consider your needs (does your dog pull enough to require a front clip harness, or will a back clip be fine?) and your dog’s preferences (does he mind something going over his head or having his legs lifted up?), and don’t forget to measure your dog before you purchase.
