Find the Perfect Fit for Your Pup
Use the guides below to find the perfect fit for your pup.
BUCKLE COLLAR
Available in 5/8", 3/4", and 1" widths.
While we strongly recommend measuring to get the most accurate fit, we understand that it's not always possible if it is for a gift or buying for a new puppy. If possible, measure the dog's neck, allowing sufficient room to slip one or two fingers between the collar and the dog's neck for some wiggle room. Consider the thickness of the dog's fur to be sure you are getting an accurate measurement. Remember, a properly fitting collar should be snug enough to stay in place, but not so tight that it causes discomfort or restricts the dog's movement.

FI QUICK RELEASE COLLAR
Available in 3/4" and 1" widths.
For our Fi Quick Release Collars with a fixed size, it is essential to accurately measure your dog's neck where the collar is usually worn, as these collars are NOT adjustable. Consider the thickness of the dog's fur to be sure you are getting an accurate measurement. Remember, a properly fitting collar should be snug enough to stay in place, but not so tight that it causes discomfort or restricts the dog's movement.
We do not recommend using an existing collar to take your measurement, as there is no general sizing rule for collars — sizes can vary significantly between brands and styles. Always measure your dog's neck directly for the most accurate fit.
Available in sizes 11" to 24.5" in half-inch increments.
HOUSE COLLAR
Our House Collars are a fixed slip-on design connected with an O-ring — NOT adjustable. It is essential to accurately measure your dog's neck where the collar will be worn. Consider the thickness of the dog's fur to be sure you are getting an accurate measurement. The collar should slip over your dog's head easily while remaining snug enough to stay in place during everyday wear.

Available in 5/8", 3/4", and 1" widths. Sizes range from 11" to 24.5" in half-inch increments.
Measuring the Head
Measure the widest part of your dog's head with a measuring tape. To check if the size you measured is correct, slip the tape measure on and off your dog's head at that width — it should slide on and off easily without being too loose.
Measuring the Neck
Measure your dog's neck with a measuring tape. Always make sure you're leaving a little extra room — you should be able to easily fit two fingers between the measuring tape and your dog's neck.
