For a collar to be safe, it must fit correctly. You will want to carefully measure your dog's head and neck to find the best fit.
The martingale should be fitted very snugly around the top of your dog's neck when the collar is tightened. You should be only able to fit one finger between the neck and the collar. The snugger it fits, the more evenly you distribute the pressure around the dog’s neck. It should be skin-tight but not so tight it chokes your dog.
To find the best fit, we recommend the following steps:
A. Using a soft tape measure or string, determine where a collar would normally sit upon your dog’s neck. Make the tape snug, but not tight. Once the tape measure has been fitted around the neck, and you can easily slip two fingers between the tape and the neck, you have found your collar size. Be sure to write down the measurement!
B. Using the same steps in A, measure your dog’s head starting at the throat and going around the head, including the ears. The collar should be large enough to fit around the head, ears, and neck. After you finish measuring, record the sizes, so you can determine the best collar size for your dog.
If your dog’s measurements fall between two different sizes, we recommend ordering a custom sized collar (we do not charge extra)!
Dog collars should be measured by the neck circumference of where the collar will sit. They should fit snugly enough to not slip over your dog's head but also have enough room to fit two fingers between your dog's neck and the collar.
All our collars have adjustable lengths. This provides leeway to alter the size either way accordingly (looser / tighter).
The width of the collar should be proportional to your dog's size. A collar width of at least 2.5 cm (1 in) is suitable for large dogs, and 1.5 cm (5/8 in) for small dogs.
Harnesses need to be fitted such that they are snug all around to avoid shifting of the harness, and it is important that the barrel strap is positioned slightly behind the armpits, not touching the elbow. Measure around the dog's barrel where the barrel strap will be placed. Select a size with this measurement in the middle of the given range of sizes.
