Sizing Guide

The "Neck Sizes" correspond to the actual measurements of your dog. Use our guide at the right to better assist you when you are measuring your dog. For collars, measure the pink area. For harnesses, you will need to measure the blue area.

When measuring your dog, use a flexible measuring tape or string and measure loosely around your pet's body to assure a comfy fit. All products are sized in inches.

Still not sure?

If your dog falls between two sizes and you are unsure which one to choose, you can select the larger size and in your order comments when you checkout, please include your dog's actual measurement and we can custom size it for your pup.


Pink Puppy offers collars 3/4", 1" and 1 1/2" wide. 3/4" collars are perfect for small dogs and puppies. 1 1/2" collars are best for medium/large shorthair dogs. 1" collars are for medium-large dogs as well as smaller dogs with longer necks.

How to Fit Martingale Collar

Martingale collars are measured as the size of the dog collar without the martingale loop. They should be fitted so they are snug (but not choking) around the dog's neck when the martingale loop is pulled close. Different dogs may require martingales fitted with slight variation. Please keep that in mind when choosing your collar size.

The general trick to fitting a martingale collar is to position the collar at the smallest part of the neck just behind the ears.  Then pull on the martingale loop to tighten the collar (as if your dog was pulling) to determine the distance between the two metal ends on the main part of the collar (typically these are O-rings, D-rings or a figure 8 slides).  Then adjust as specified below… 

For the majority of dogs…
Adjust the collar so that when the two metal ends meet but do not overlap when the martingale loop is pulled. 

For dogs extra talented at slipping their collar or during training…
Adjust the collar so the metal ends do not touch even when the martingale loop is pulls really tightly (leaving about one inch between then). With this fitting, when the collar is not in use (such as when you dog is in the house) it is safest and more comfortable to adjust so the collar is more slack.  Alternatively, you can use a regular collar for everyday wear and to hold your dog’s tags and then just use your martingale when going out on the leash.

Harness Sizing

Our dog harnesses are custom sized for your dog. Just provide your dog's chest measurement. Harnesses are adjustable and should have some wiggle room in either direction to assure a comfortable and secure fit.
