Sizing Guide
Standard Sizes
Our standard sizes for collars are designed with holes 1 inch apart, starting at the smallest measurement and ending with the largest. For example, our Medium collar has holes at 15″, 16″, 17″, and 18″. We’ve done this so your canine endeavour collar can change with your pup!

Custom Sizes
We are more than happy to make your dog’s collar to your exact sizing measurement! We know that sometimes a dog may fall outside of the standard sizing we have outlined above, that’s why we also offer custom sizing! Send us a message if you are interested in a custom size for your dog’s collar!
How to Size a canine endeavour Collar
Sizing your dog for their new collar is easy. Take their current collar, lay it flat, and grab a measuring tape. If you have a buckle collar, measure from the midpoint of the buckle to the hole that you use to secure the collar. If you have a clasp collar, measure the entire length of the collar (from clasp to clasp). We will add additional holes so that you can adjust sizing if necessary.
Recommendation: Dog collars should fit snug (but not tight), with enough room for approximately 2 fingers to fit between your dog’s neck and the collar.
How to Size The canine endeavour Headcollar
Sizing your dog for The Headcollar is easy but needs to be done carefully. Using a measuring tape, measure the neck and nose circumference of your dog. Measure your dog’s nose at the widest part, just below their eyes. Measure your dog’s neck at the highest point, just below their ears and under the nose where the head meets the neck. We will add additional holes so that you can adjust sizing if necessary.
Recommendation: The Headcollar should fit snug but the dog’s mouth should be able to fully open. The dog must be able to drink water, bark, and pant while wearing The Headcollar.
How to Size a canine endeavour Harness
The canine endeavour Harness is completely customized to your dog’s size! Grab a fabric measuring tape and follow the instructions below to size your pup.
To size your dog for their new harness, you first need to find the tops of your dog’s shoulder blades (above and slightly behind your dog’s front legs). Once you find the shoulder blades, the following three measurements are required for us to make the harness:
- Chest: Measure from the top of the left shoulder blade, around the front of your dog’s chest, to the top of the right shoulder blade. Keep the measuring tape level (ensuring your hands are even on both sides) the entire time.
- Shoulders: Measure the space between your dog’s shoulder blades (top of their back). Start at the top of the left shoulder blade, bring the measuring tape over your dog’s back, and end at the top of the right shoulder blade.
- Girth: Measure the widest part of your dog’s torso by starting just behind the left shoulder blade, measuring completely around the torso, behind the right shoulder blade, and end where your first started the measurement.
