Due to this collar being custom made to your measurements & color preferences we cannot accept returns or exchanges. Please double check your measurements & feel free to email me with any questions prior to ordering at
Please add the following in the “notes” section at checkout:
  1. Add your pup's EXACT measurements. If either measurement (A or B) is larger than measurement (C) we will make the collar slightly larger to ensure it will slide off & on comfortably.
  • Made with heavy duty BioThane in either 3/4" or 1" width
  • 100% Waterproof
  • Stink proof/Mildew proof/Dirt proof
  • Classy look & available in a variety of colors
  • BioThane is flexible, similar to the feel of broken in leather (even in freezing temperatures)
  • Vegan, low maintenance, easy to clean
  • Very Durable, will last longer than leather & nylon
  • Reinforced with heavy duty screws at all stress points to ensure for the strongest hold. We believe screws are the most durable as the threads are tightened & reinforced to ensure your collar will never come apart.

*Brass is extremely strong & durable. However, keep in mind brass has a natural patina/tarnish when it's exposed to certain elements, which is completely unavoidable. You can clean and polish your brass hardware using a jewelry cleaning cloth. 

It is very important to carefully measure your pup to get accurate measurements as these collars are NOT adjustable. The best to way to measure for these style collars is with a soft measuring tape or string. The tape should be snug (don't include finger spacing when measuring). If your dog has very thick fur be sure to get the tape closer to the skin.

Measure the following 3 areas:
- the widest part of your pup's head (A)
- the neck just behind the ears (B)
- the neck where the collar naturally sits (C)

As this type of collar slides over your pup's head & is non-adjustable, if either measurement (A or B) is larger than measurement (C) we will make the collar slightly larger to ensure it will slide off & on comfortably. Please add your pup's EXACT measurements & we will size it accordingly.

If you are unsure about the proper size you should order, please feel free to email me at
