A Complete Guide to Puppy Harnesses

Congratulations on your new four-legged family member! Now you’re shopping in preparation (or picking up last minute bits), you might be wondering whether your puppy can wear a harness? The answer is yes! It’s important you pick what is most comfortable for your puppy, and a harness is a popular option.

The harness has two primary aims – one, to enhance safety and two, to offer comfort. Dog harnesses were originally developed to assist working and rescue dogs with pulling loads and undertaking rescue operations, but designs have evolved, with an ever-growing range of products available for pet parents looking to ensure that their furry friend is comfortable and content on their daily walk.

When it comes to finding the right time to put a harness on your pup, it can all depend on their breed, temperament, and stage of training.

Typically, a more mature dog will take a harness pretty well, with some exceptions, of course. But when it comes to training a puppy, you can begin training them on the lead from the day you pick them up, as long as you’ve ensured that the harness fits comfortably and securely. This is because, unless you’ve bred your own pup, you’ll bring them home at around eight weeks old, but it’s advisable to give them a couple of days to rest and get used to their new environment before you pop a harness on them.

However, you do need to take into consideration the individual needs of your pup. If they’re particularly nervous or not settling very well, then you may want to hold off on using a harness for the first few weeks. If you’re unsure, always talk to an expert like a vet or dog trainer to get tailored advice for your fluffy friend.

Dog parents want the best for their companions and it’s natural to have questions about collars, leads, head halters and harnesses and whether to get a collar or harness for a puppy.

On the one hand, collars are quick and easy to fit and many dogs behave very well on a lead, but harnesses can often be advantageous for puppies because they are so enthusiastic and energetic.

With a harness, you can keep your pup under control, you don’t have to worry about their neck or their breathing if you have to tighten your grip and puppies are less likely to pull in a harness. Harnesses can also be beneficial for puppies that are learning how to walk and respond to commands.

Puppy harnesses have become more popular in recent years as there are a whole host of benefits to wearing one, including:

Reduces pulling

It’s natural for dogs, especially puppies, to want to get out of the house and discover new sights, sounds and smells. Unfortunately, for many parents, this means that they end up being walked by their dog, rather than the other way round.

If your puppy pulls when using a collar or a slip collar, buying a harness can help to discourage pulling and make your walks a little more enjoyable. You can also buy anti-pull harnesses, which are designed to encourage dogs to avoid pulling by increasing resistance on the chest.

More comfortable

We all love our dogs and want them to be happy and comfortable all the time. One of the most significant advantages of using a dog harness rather than a collar is that they reduce pressure on the neck.Additionally, harnesses can be particularly beneficial for breeds that are prone to breathing problems. If you have a flat-faced breed, for example, a Pug or an English or French bulldog, harnesses help to redistribute the pressure to facilitate breathing.

Improved safety

For most pet parents, there is nothing worse than the thought of their dog slipping off the lead or ducking out of a collar and ending up on a busy road. Harnesses are much more robust and secure than a collar, which increases safety as well as giving dog parents peace of mind.

There’s a harness for every pup

As harnesses have become more popular, the range of products has expanded significantly. There is now a dazzling array of harnesses for small dogs, large dogs, puppies – you name it, there’s a harness for it.

You can choose from different sizes, add reflective strips or stitching for night walking and you can even get additional features such as padded chest plates for enhanced comfort.

Whether you plan to be in sole charge of your puppy’s exercise regime, or you’re hoping to get a dog walker involved whilst you’re busy, it’s important to ensure that your pup is kitted out and ready to go out and start exploring.

When it comes to puppy harnesses, it’s not one size fits all! Harnesses come in a huge range of styles and sizes, suitable for different breeds and training requirements. The main types of puppy harnesses include:

There are two main types of no-pull dog harnesses. The first has a clip at the front of the harness, rather than at the back of the neck to discourage the dog from pulling. The second, known as a dual-clip harness, has a front and back clip for additional control – these are more commonly used by dog trainers.

Getting the right harness fit for your puppy starts with a few simple measurements, and it can make a big difference to their comfort and safety on walks. Using a soft tape measure, gently measure around the widest part of your puppy’s chest (just behind the front legs), as well as around their neck, where a collar would naturally sit. It’s best to do this while your puppy is standing, as this gives the most accurate size, although a few treats can help keep even the wriggliest pups still! Once you have these measurements, compare them with the sizing guide provided for your chosen harness, and if your puppy is between sizes, opt for the larger option to allow room for growth. A well-fitted harness should be snug but not tight - you should be able to slip two fingers comfortably underneath. Taking the time to measure properly helps ensure your puppy stays happy, secure, and ready for plenty of tail-wagging adventures.

Every day is an adventure when you’re a puppy parent, especially when it comes to leaving the house and getting out into the great outdoors. Training is hugely beneficial from an early age and it can make an incredible difference to your dog’s behaviour, including the way they interact with other dogs and humans who cross their path.

If you’re using a harness instead of a collar for the first time, here are some tips to help your dog get used to a chest strap, vest or a no-pull harness:

Introducing the harness to your puppy

Before putting it on, allow your puppy to sniff and investigate the harness. Reward your pup’s curiosity with treats so they associate the harness with something positive. This will help encourage your pup to enjoy wearing their harness.

 

Placing the harness over your puppy's head for the first time

Hold the harness open and identify the front, back, and leg holes. Many harnesses have a label or handle that sits on your puppy’s back (this helps you orient it correctly). Depending on the style, either guide your puppy’s head through the neck opening or place one paw at a time into the leg holes. Move slowly and reassure them with a calm voice.

Gently place the harness on the dog’s body while encouraging them to sit. You can use a treat to reassure them. Take the harness off and repeat several times, leaving it on for a longer period each time.

Leave the harness on and let them get used to wearing it before you leave the house.

If your puppy backs away the moment the harness comes near their head, don’t try to push through it - this usually makes them more nervous and can turn it into a long-term struggle. Instead, think of it as a training moment rather than a quick task. You need to try and build up the positive association with the harness which may take time.

Doing the harness up

Bring the straps around your puppy’s body and clip or fasten them securely. You should hear a click if it’s a buckle-style harness.

Adjust the fit to ensure that your puppy is comfortable and happy before you start walking. Make sure the harness isn’t rubbing under the legs or sitting too close to the neck. Check that it doesn’t restrict movement and that your puppy can walk comfortably.

Encouraging your puppy to walk with their harness on

If your puppy freezes or flops, don’t worry - it’s completely normal and very fixable with a bit of patience (and a lot of tasty bribery).

Start by helping your puppy feel comfortable simply wearing the harness indoors. Let them walk around the house for short periods while you offer praise and treats, so they associate it with positive experiences rather than pressure to perform. Keep your tone light and encouraging - think “good pup!” and “let’s go!” - so it feels like a game, not a task.

When you’re ready to get them moving, begin with a few steps at a time. Crouch down, call their name, and reward even the smallest movement towards you. You can also use a favourite toy or treat to gently lure them forward - sometimes curiosity is stronger than stubbornness! If they take a step, celebrate it like they’ve just won “best in show” at Crufts (it’s all about your tone and response).

Keep early sessions short and low-pressure, whether you’re indoors or in a quiet garden. Avoid pulling on the lead, as this can make them resist more - instead, encourage them to come to you willingly. If they stop, pause with them, then try again with encouragement rather than force.

Consistency really pays off here. The more your puppy realises that wearing a harness leads to fun, freedom, and little rewards, the quicker they’ll start trotting along happily. Before long, you’ll have a confident, tail-wagging walking buddy who’s ready to explore the world.

Please note: if your puppy remains unwilling to wear a harness, that’s a clear sign a collar may be the best option for your new family member.

Using voice commands to encourage your puppy while wearing their harness

Using clear, upbeat voice commands can really help your puppy feel relaxed and confident when it’s time to put on their harness. The key is to keep your tone positive and consistent, so your pup begins to associate the harness with rewards and fun (and, of course, walkies).

You might start with simple, encouraging phrases like “harness on” or “get ready” as a cue that it’s time to put it on. As you guide them into the harness, use calm reassurance such as “good pup”, “that’s it”, or “nice and easy” to keep them settled. If your puppy needs to step into the harness, commands like “paw” or “step in” can be really helpful once they’ve learned what they mean.

Once the harness is on, reinforce the experience with enthusiastic praise like “yes!”, “good job!”, or “let’s go!” so they link wearing the harness with something exciting. If your puppy seems unsure, a gentle “it’s okay” in a soothing tone can help build trust.

Consistency is key - using the same words each time helps your puppy learn faster. Before long, those cues will have them happily wagging their tail and getting ready for their next adventure.

Harnesses can provide greater control and comfort and they can also enhance safety and support, reducing pressure on the neck and preventing dogs from pulling. If you have a puppy, or you’re getting ready to welcome a new canine companion to the family and want to buy a harness, make sure you take your time comparing products and ensure you measure your dog for the perfect fit. You’ll both be heading out on enjoyable walks in no time.
