Choosing the right type of harness buckle

When choosing a new harness for your dog, a main priority should be the strength and durability of the materials and parts, as this will make sure your walks, runs and trips to the park will be safe and secure.

One of the key components in any dog’s harness is the buckle, which is typically made from either machined plastic or metal. But while brushed metal may look the part, does it really offer many benefits that can’t be found in modern, toughened plastics? And which type is the best option for your pup?

This guide will help you identify the pros and cons of each material, which breed they are most suitable for, and the importance of finding the right balance of features for your individual pups.

Advantages of metal buckles

For large breeds, strong pullers, or simply for owners who prefer a premium, ultra-durable option, a metal buckle is often the way to go.

• Strength: Metal buckles, particularly those made from stainless steel or solid brass, offer significant strength and a higher load-bearing capacity. 

• Durability: Metal buckles can withstand heavy use and the test of time. Stainless steel is particularly resistant to corrosion, making it a great choice for dogs who love to swim.

• Premium feel: A solid metal buckle with a brushed finish provides a sleek, stylish look.

Disadvantages of a metal buckle

• Noisy: The clanking of a metal buckle can be irritating for both you and your dog.
• Prone to corrosion: Unless it is made from stainless steel, most metal buckles will eventually rust when exposed to rain and mud.
• Affected by temperature: Metal can get freezing cold in the winter, and can become hot to the touch in direct summer sun, making your dog more uncomfortable in extreme weather.
• Stiff operation: The mechanisms can be stiff and difficult to fasten or unfasten, particularly in cold weather.
• Heavy: While the size and durability of metal buckles have positives, they add additional weight to the harness, which can be uncomfortable for smaller dogs.

Advantages of plastic buckles

The materials used in a premium buckle today are a world away from the brittle plastic of the past. These are high-grade, engineered materials that are incredibly strong, durable, and specifically designed for high-performance applications, making them more than capable of keeping your dog secure.

Here’s why these modern buckles are the ideal choice for almost every dog:

• Comfort: For small dogs, puppies, and breeds sensitive to weight, a plastic buckle is often the more comfortable option. A lighter harness is also less intrusive and allows for more natural movement.

• Strength: Don't underestimate the power of a good quality plastic buckle. The load-bearing capacity of a quality plastic buckle is more than sufficient to hold even the largest dog breeds.

• Weatherproof: Engineered plastic is completely waterproof, will never rust, and maintains its strength and integrity in all conditions.

• Variety and affordability: Plastic buckles come in a huge array of colours and are generally more affordable than their metal counterparts.

Disadvantages of a plastic buckle

• Susceptibility to chewing: While they are very durable, a determined dog could potentially chew through a plastic buckle.

• Perceived lower strength: Compared to a solid metal equivalent, a standard plastic buckle has a lower ultimate breaking strength, but this is still more than strong enough for use in a dog harness.

“For everyday walks with a small or medium-sized dog that doesn't pull excessively, a well-made plastic buckle provides a fantastic combination of security and comfort.” - John Skinner, TopDog co-owner.

For small breeds, puppies, and seniors

A plastic buckle. Smaller breeds, very young dogs, and those that struggle with mobility can all benefit from wearing a lightweight and comfortable plastic buckle. Fitting a metal buckle for dogs in this category would be uncomfortable and add unnecessary weight to their harnesses.

For everyday walks with medium to large dogs

A plastic buckle. A high-quality plastic buckle offers the ideal combination of performance and comfort for the typical medium to large dog.

While dogs of this size would not have issues with the weight of a metal buckle, plastic is lighter and more comfortable, particularly at the height of summer or in cold, wintery conditions.

For powerful pullers and large breeds

A metal buckle. With a higher load-bearing capacity than plastic buckles, the added strength may be a reassurance for owners with dogs that are particularly strong, or are persistent pullers.

For dogs that love swimming and mud

Plastic or stainless steel buckles. Both high-quality plastic buckles and stainless steel buckles are excellent choices due to their water resistance, strength, and integrity in all conditions. However, avoid metal buckles that are not made of stainless steel if you have a water-loving dog.

Our Recommendation: Balance, strength and comfort

While metal buckles have strength, they are heavy, noisy, and non-stainless steel models are susceptible to weather. Modern plastic polymer buckles provide the security you need without these drawbacks and provide a balance of strength, lightweight comfort, and all-weather durability. 

For a reliable and comfortable harness that enhances your walking experience, a high-quality plastic buckle is the clear choice.
