Wide Collars and Wide Martingale Size Guide
There are no standard collar sizes so please measure your dog before ordering to ensure the collar fits.
Use this dog collar size chart by first measuring your pup's neck with a soft tape measure, pulling it snug but not tight. No tape measure on hand? A piece of string works too; just measure the string against a ruler afterward. Whichever method you use, leave enough room to slip two fingers between the collar and your pup's neck.
Wide collars are 1.5 inches wide.
| Neck Circumference | Width | |
| M | 13-21" | 1.5" |
