The Safety Behind Selecting the Right Size Harness for Your Dog

When it comes to dog safety, one of the most overlooked details is making sure your dog harness fits properly. A lot of pet parents focus on the color, style, or whether it’s a no-pull design, but the truth is, the size and fit of a dog harness play a much bigger role in keeping your furry friend safe. A harness that’s too loose can let your dog slip out in the middle of a walk, and one that’s too tight can cause rubbing, restricted movement, or even breathing issues.

Choosing the right size isn’t complicated, but it’s not something you want to guess. Dogs come in all shapes and sizes, and two dogs with the same weight can have completely different body proportions. That’s why knowing how to fit a dog harness correctly is essential. Start by measuring your dog’s chest girth — this is the widest part of their chest, just behind the front legs — and their neck girth at the base, where the harness will sit. Use a flexible measuring tape, and always check the size chart for the specific brand you’re buying. Every manufacturer’s sizing is a little different, so don’t assume that a “medium” is the same across the board. you can also utilize out Dasko Gear sizing guide to help fit your outfit your dog with any of our Dasko Gear. 

Once you’ve chosen the right size, make small adjustments so the harness sits snugly without being restrictive. The two-finger rule is a good guideline — you should be able to slide two fingers between the harness straps and your dog’s body. If it’s too tight to do that, loosen it; if it’s so loose you can fit more than two fingers easily, it’s time to tighten up. A well-fitted harness will stay centered on your dog’s chest and not shift to the side during walks.

Pay attention to how your dog moves and behaves once the harness is on. If they’re chafing under the arms, pulling out of the harness, or panting heavily even on short walks, something’s off with the fit. Remember, the goal of a harness isn’t just control — it’s comfort, mobility, and, above all, safety. Whether you’re using a dog harness for everyday walks, hiking adventures, or training sessions, a proper fit keeps your dog secure and happy.

Dog safety starts with the basics, and learning how to fit a dog harness the right way is one of the simplest yet most important things you can do for your best friend. Take the extra few minutes to measure, adjust, and test before heading out the door — your dog will thank you with a safer, more enjoyable walk every time.
