How to Choose a Puppy’s First Harness

Bringing home a puppy is exciting, and that first set of walking gear matters more than you might think. A harness that's comfortable and well fitted helps your puppy build a positive association with walks, while one that pinches, rubs or restricts movement can put them off wearing it altogether.

Here's what to look for, and why you shouldn't expect your first harness to be your last.

Expect to Buy More Than One

Puppies grow fast, sometimes noticeably from week to week. Most puppies will go through at least two harnesses before they reach adult size, and larger breeds can need three or four as they develop. Choosing a harness with plenty of adjustment will help you get the most out of each size, but it won't stretch to cover every stage of growth.

What to Consider for a First Harness

Fit. The harness should sit snugly without squeezing. You should be able to slide two fingers comfortably under any strap, and it shouldn't shift around or twist when your puppy moves. Check that nothing sits tight behind the front legs, as that's where rubbing most often starts.

Weight. Puppies are small and still developing, so a heavy harness with lots of bulky hardware can be tiring and overwhelming. Look for something lightweight that your puppy barely notices.

Comfort. Soft, smooth materials and a design that doesn't restrict the shoulders or limit natural movement are important. If a puppy is uncomfortable, they'll often let you know through their behaviour, not just by trying to wriggle out.

Adjustability. Multiple adjustment points let you fine-tune the fit around the chest and body, and extend the life of each harness as your puppy grows. Our puppy harness range is chosen for being highly adjustable, lightweight and non-restrictive.

Quality. Every harness we stock is independently strength tested and also tested in-house, so you can feel confident in what you're buying, even for a small puppy.

Which Harness Suits Your Puppy?

Toy and very small breeds: The Ruffwear Hi and Light is a great choice. It's our most lightweight harness, with the softest liner and the smallest hardware.

Larger breeds: The Horizon Harness is usually our top choice. It has an adjustable chest strap, so you can lengthen the harness at the same time as extending the girth and neck straps, which really helps as a big puppy grows.

Small and medium breeds: You can pretty much take your pick. The Adventure Harness 2.0 and the Adventure Lite Harness both offer a huge range of adjustability, plus a neck clip so the harness doesn't have to go on over your puppy's head. They're solid, well-made harnesses and are some of the best suited to use for both walks and restraint in the car.

Keep Checking the Fit as They Grow

A harness that fitted perfectly a few weeks ago may not fit now, and growth spurts can sneak up on you. Make it a habit to check the fit weekly, and always before a longer walk.

Signs your puppy may be outgrowing, or struggling with, their harness:

• Straps that are tight, digging in, or leaving marks or flattened fur
• Rubbing or sore patches around the armpits or chest
• A shorter or altered stride, or looking stiff when walking
• Reluctance to have the harness put on, such as backing away, freezing or hiding
• Scratching or fussing at the harness, or increased frustration on walks

Discomfort can show up as unwanted behaviours: pulling, nipping, refusing to walk, or becoming difficult to harness. Before assuming it's a training issue, check the fit first.

It's also worth knowing that a puppy who's had an uncomfortable experience with a harness can develop an aversion to it, which takes time and patience to undo. Replacing a harness as soon as it stops fitting is much easier than rebuilding trust.
