How To Measure for a Dog Collar

Choosing the right dog collar can be a challenging task. One of the most important factors is whether the collar will fit right.

This means checking if the collar is too loose or tight for your furry family member. A loose dog collar may cause safety concerns since it slips off easily. 

This will make it easier for your dog to run off or escape. Also, there’s a likelihood that the loose collar will get stuck on another object and suffocate your pet.

On the other hand, using a too-tight dog collar may choke your dog and cause health problems. It may also make breathing difficult for them or cause skin irritation when the collar starts to rub against your pet’s skin.

The good news is you can avoid all these problems by selecting a collar that fits your pet properly. And you can do that by learning how to measure for a dog collar. If you don’t know how, check out our step-by-step guide below, plus other things to consider when buying a dog collar. 

Does My Dog Need a Collar?

Dog collars serve two primary purposes.

  1. They keep your dog safe. With the right collar, you know your dog is safe and comfortable when you take them for a walk.
  2. As a means of identification. You can attach a dog tag to them so the pet can be identified if they wander away

Steps to Determine Your Dog's Collar Size

1. Consider your dog’s age and breed

You should consider their age and breed to get the best possible collar for your pet. If you have a little puppy, it’s a good idea to invest in a large or puppy collar with an adjustable size range since puppies grow quickly. 

This also means that your dog’s neck size will grow from 8 inches to 9 to 5 inches.

On the contrary, opt for the smaller sizes if your four-legged pal is already fully grown and it is in between the sizes available in the dog collar market.

For example, a dog’s neck that measures 22 inches should ideally get a collar that ranges from 18 to 24 inches. Considering their neck measurement, your dog can move comfortably. 

Furthermore, the extra material hanging off the end of the collar will not cause irritation.

2. Measure your dog’s neck size 

The next step is to measure your dog's neck size by using these methods:

Use a soft tape measure or piece of string

Use a soft measure tape or even a piece of string lying around your home to get flawless results. Position the tape around your dog’s neck below the head. 

Loosen the soft tape a bit (we’ll explain it later using the two-finger rule), so your dog can freely move with it. Overlap the measuring tape below your dog’s jawline for an accurate result. 

After finding your dog’s collar size, note the number and buy a collar within its size range. 

For example, your dog’s neck is about 18 inches. In that case, you can choose a collar within the 16 to 20 inches size range. Some pet owners prefer to buy the dog collar with the highest range to account for their dog’s growth.

There are also pet owners who prefer the smaller size range. That way, there won’t be extra material that hangs off the end of the collar. And some pet parents choose the middle range, so they can adjust up and down as needed.

Measure the current collar

Another option is to remove your dog's current collar, stretch it flat, and measure from the middle of the buckle to the current sizing hole. Mark the endpoint after adding two to three inches. 

The collar size you mark using this measurement method is often accurate if you’re careful and focused. But why add two to three inches? 

3. Add one to two inches to the total collar measurement

Adding one to two inches or using the two-finger rule helps you determine the best-sized dog collar.

The two-finger rule

To do this, simply slip two fingers into the tape measure loop that you’ve wrapped around your dog’s neck. This allows for enough movement and breathing space for your dog. 

Make sure that only two fingers can fit. If you can fit three or more fingers in the collar, it will end up too loose. Contrastingly, if the gap can only fit one finger, it will be too tight.

4. Get a new collar

Once the measurement is done, visit the market or check out online to get a new collar for your canine. Some options include martingale collars, rope collars, flat dog collars,  tactical collars, or smart collars with tracking devices.

The most common type of dog collar is a flat dog collar, while the most durable type is the tactical one. It is both durable and comfortable at the same time because of its ergonomic design.

5. Try on the collar

The last step to finding the correct collar size is to place the collar around your dog’s neck. Put the accessory beneath your pet’s jawline while leaving a small gap between the fur and the collar.

Adjust the strap until the accessory fits if you opt for a collar with a plastic chip. Meanwhile, adjust the collar until there’s enough wiggle room between your dog’s fur and the accessory if you prefer a collar with a belt buckle.

Other Things to Consider When Choosing a Dog Collar

Dog collars are available in different styles, patterns, and colors.

If you prefer a customized design, choose a collar with unique patterns or a bowtie collar. Remember to use a collar with a tag to make it easy to locate your dog in case they’re lost. 


Dog collars are made from different materials. Yet, not all materials may suit your pet. For instance, a nylon collar may be your best bet if you buy a durable and inexpensive dog collar.

If you want something classy, you may go for a leather material or one made with stainless steel (Cuban dog links). Check your dog's existing collar, and you will likely know what material your pet is comfortable with.
