Collar Size Guide
Even though you can expect some degree of adjustability with your new dog
collar, it is important to measure your dog carefully.
Collars: If you are satisfied with the fit of your dog's current collar,
measure that collar from the center bar of the buckle to the farthest
hole. Our collars are sized according to this measurement, not to the
over-all length of the collar, which varies by manufacturer and by
whether it is a buckle-end or a dee-end style collar. (see diagram
If this is your dog's first collar or you need a collar in a different
size, measure around the dog's neck with an allowance for 2 fingers to fit
between the dog and the collar. The collar shouldn't be so tight that it
will cause discomfort or so loose that it slides over the dogs head.
Martingale Collar Sizing Guide
Measure carefully as these collars are sized differently than standard collars.
When measuring Martingale Round/Rolled Collars and Martingale Shearling Lined Collars, keep in mind the collar needs to slip over your dog’s head as there is no buckle.
First, measure the widest part of your dog’s head. Next, measure your dog’s neck as you would for a standard, buckle-style collar. Use the larger of the measurements to select a collar that fits between the ranges listed.
Sizes Fit Range
10” 5-1/2” to 10”
12” 7-1/2” to 12”
14” 10” to 14”
16” 12” to 16”
18” 12” to 18”
20” 14” to 20”
22” 16” to 22”
24” 18” to 24”
26” 20” to 26”
Harness Sizing Guide
Standard Harness: Select a harness using the measurement of the
girth - the measurement around the dog's chest just behind the front
legs - allowing space for 2 fingers to fit between the harness and the
dog's body for a comfortable fit.
"THE HARNESS" Leather Dog Harness is available in girth sizes from
30" to 40". To determine the proper size harness, measure around the
girth, the area behind the front legs but in front of the belly, of the
The Figure 8 Harness is easy to fit and easy to put on and take off.
To determine the size needed, use a tape measure to measure around the
pet's neck, criss-crossing at the shoulder blade and then measuring down
around the chest. This measurement will be the measurement of the
harness to the longest hole of the harness. Be sure to select a size
that allows room for adjustment both larger and smaller.
Auburn Leathercrafter's Leather TRACKING HARNESS has four adjustable buckle straps
that will accommodate dogs in a wide variety of shapes and sizes, from a
dog with a 28" girth to a dog with a 42" girth. Simply (but carefully)
measure the girth of the dog, that is the measurement just behind the
front legs. Then find the necessary tracking size based on the sizes
and ranges specified.
- Remember that puppies grow quickly, so it is important to check the
tightness of your dog collars and harnesses often. Inspect and replace a
collar or harness as it shows signs of wear.
- Remember, a rule of thumb is to leave an allowance for two fingers
to fit between the collar and the dog for a comfortable fit.
