Why Dog Collar Width Matters

Many dog owners focus only on neck size, but collar width also plays a big role in safety and comfort.

A properly sized collar should:

• distribute pressure evenly around the neck
• provide enough strength for your dog’s size
• remain comfortable for everyday wear

Wider collars are typically stronger and more durable, while narrower collars are lighter and better suited for smaller dogs.

Dog Collar Width Guide

Here is a simple guideline many dog gear makers, including LUIDO Pet Gear, use when designing collars.

13 mm Dog Collar

Best for small dogs up to around 15 kg (33 lbs).

This width is lightweight and comfortable for smaller breeds while still providing enough durability for everyday walks.

Common examples:

• miniature poodles
• dachshunds
• small terriers
• similar-sized dogs

16 mm Dog Collar

Ideal for dogs up to around 25 kg (55 lbs).

This is one of the most versatile collar widths because it provides a good balance between comfort and strength.

Suitable for:

• medium-sized dogs
• active companion dogs
• everyday walking and training

19 mm Dog Collar

Recommended for dogs up to around 35 kg (77 lbs).

This width offers increased durability and control, making it a great choice for stronger or more energetic dogs.

Often used for:

• larger companion dogs
• active breeds
• dogs that pull during walks

25 mm Dog Collar

Best for large and strong dogs over 35 kg (77 lbs).

A wider collar distributes pressure better and provides maximum durability for powerful breeds.

Ideal for:

• large breeds
• strong dogs
• dogs that require extra control

Does a Wider Dog Collar Mean More Control?

In many cases, yes.

A wider collar can help distribute pressure more evenly around the neck, which can make walks more comfortable for stronger dogs. However, the best width always depends on the dog’s size and strength.

For smaller dogs, a narrower collar is usually the better choice.

What About Martingale Collars?

Martingale collars are often slightly wider than regular collars because they provide gentle control without choking.

They are commonly used for:

• dogs that slip out of regular collars
• training situations
• breeds with narrow heads

Many dog owners prefer martingale collars for breeds like greyhounds or energetic dogs that tend to pull.

Final Thoughts

Choosing the right collar width helps ensure both comfort and safety during everyday walks.

As a general rule:

• small dogs benefit from narrower collars
• medium dogs need balanced width and strength
• large dogs require wider, more durable collars

When selected correctly, a well-fitting collar will make walks safer and more comfortable for both you and your dog.
