How to Measure Dog Collar Size

A comfortable snug collar is paramount for your fur companion as it provides the desired safeguard for him. Ensuring that the neck of the dog is accurately measured and the size of the collar selected is extremely essential to preventing a situation where the collar can be too loose or tight, which may not give the dog comfort or even be injurious.

Let’s Get Started

Materials Needed for Measuring a Dog’s Collar

To accurately measure your dog’s neck for a collar, you will need the following materials:

• Flexible measuring tape or a piece of string: The cloth measuring tape option best serves this purpose, as it will follow the dog neck shape form. If you don’t have a measuring tape, use a piece of string or ribbon instead.
• Ruler or rigid tape measure: In case of a tape or ribbon to measure its dog’s neck, you will need a ruler or rigid tape measure to determine length of string or tape after measuring had completed.
• Pen or marker (optional): If using a string, you may find it helpful to mark the spot where the string meets the end, making it easier to measure the length accurately with a ruler or tape measure.

When measuring your dog’s neck, ensure that the measuring tape or string is snug but not tight. Measure at the base of your dog’s shoulder blades, a few inches down from their head. This will give you the most accurate measurement for selecting a properly fitting collar.

Step-by-Step Guide to Measuring Your Dog’s Neck

To accurately measure your dog’s neck for a collar, follow these steps:

1. Wrap a flexible measuring tape or string around your dog’s neck, just behind the ears where the collar will sit. Make sure the string or tape is just the right amount of snug, then note the measurement. Make sure the tape or string is level and not twisted.
2. When measuring, place the tape or string at the base of your dog’s skull, where the collar will naturally sit. Allow enough room for two fingers to fit comfortably between the collar and your dog’s neck. This ensures a comfortable and secure fit.
3. For the most accurate measurement, place the tape just below your dog’s jawline. Add one inch for small dogs (10 pounds and under), two inches for medium-sized breeds, and three inches for larger dogs to the measured neck circumference. This extra space allows for a comfortable fit and easy adjustment of the collar.

Additional tips:

• Use a soft, flexible measuring tape for the most accurate measurement.
• When measuring a puppy’s collar size, add two fingers’ worth of slack to allow for growth.
• The “two-finger rule” is a helpful guide: if you can comfortably fit two fingers between the collar and your dog’s neck, it’s a suitable length.

Choosing the Right Collar After Measurement

Once you have accurately measured your dog’s neck, consider the following factors when selecting the appropriate collar:

• Collar type: Consider the type of collar suitable for your dog’s breed and behavior. Adjustable collars are ideal for growing puppies, while wider collars may be more comfortable for larger breeds.
• Size range: Compare the neck measurement with the collar size ranges to find the ideal size for your dog. If your dog’s neck measurement falls between two sizes, choose the larger size. Always consult a breed-specific size chart if possible.
• Collar fitting: For adjustable collars with quick-release buckles, ensure the dog’s measured neck size fits within the collar’s adjustable length range.
• For collars with a metal buckle, round down the dog’s measured neck size to the nearest even-numbered size.
• For martingale collars, order a collar that falls within the range of the dog’s head and neck sizes,
• For side-release buckle collars, order a collar at the dog’s neck size.
• Collar width: Consider the width of the collar based on your dog’s size.
• Narrower collars are suitable for small dogs, while wider collars are better for larger dogs and those with thicker necks.
• Seasonal changes: Keep in mind your dog’s seasonal weight changes and fur thickness when selecting a collar size.

Additional Tips for Collar Fitting and Adjustment

• Regularly check the collar fit as your dog grows or their weight fluctuates to ensure it remains comfortable and secure. Replace the collar if it becomes worn out or stretched.
• Use the two-finger rule to ensure a comfortable fit: you should be able to slide two fingers between the collar and your dog’s skin. This ensures the collar isn’t too baggy or too constricting.
• The recommended tightness for a dog collar is such that two to three fingers can fit between the collar and the dog’s neck. In high-risk situations, the collar can be tightened to fit one to two fingers. A collar that is too loose may allow the dog to slip out, while a collar that is too tight can cause discomfort or health issues.
• Special cases, such as sighthounds, may require a martingale-type collar or a body harness due to their unique neck and head shape.
• The dog’s breed and size impact collar measurement; larger breeds require sturdier collars while smaller breeds need lighter ones. Always check manufacturer guidelines and adjust the collar as the dog grows.

Calculating the Correct Collar Size

Calculating the correct collar size for your dog is crucial to ensure a comfortable and secure fit. Dog collar sizes are typically determined by the dog’s neck measurement, with adjustment holes allowing for a 1-2 inch range in either direction. Small dogs usually have a neck measurement of 16 to 19 inches, medium dogs 19 to 23 inches, and large dogs 22 to 28 inches.

Common Mistakes to Avoid When Measuring for a Dog Collar

When measuring for a dog collar, it’s essential to avoid common mistakes that can lead to discomfort or injury for your furry friend. One such mistake is measuring end to end instead of from the male end of the buckle to the female end or the hole currently in use. 

This can result in an ill-fitting collar that’s either too loose, allowing the dog to slip out, or too tight, causing injuries and breathing difficulties.

Another common mistake is not allowing for some slack for comfort. Ensure there is enough space for two fingers between the collar and the dog’s neck to prevent discomfort. 

Some Other Mistakes to Be Avoid:

• Not accounting for a dog’s growth.
• Not considering the dog’s fur.
• Measuring too tightly.
• Ignoring the dog’s head size, as the collar should be larger than the neck but smaller than the overall head size to prevent slipping off
• Adding too much slack for aesthetic purposes, as adding more than 1-3 inches to the required size can cause the collar to be larger than the dog’s head, allowing it to slip off.
