The following information and sizing chart is meant to help in picking your pet's collar size correctly

  • Angel buckle style "collar size" refers to the length from one end of the leather strap to the other end, not including the buckle.
  • Please refer to the "neck size" for the actual fitting size.

For example: An Angel 24" collar will not fit a 24" neck. The 24" size refers to the overall length of the leather strap. The 24"Angel collar will fit any dog with a neck size between 17.5"- 22". The optimal neck size for the 24" collar would be around a 20" neck, as it would buckle at the middle hole.

  • Measure the middle of your dog's neck. Use that measurement to locate the correct "neck size" within the chart below. If for example your dog's neck measures 12.5", your best choice would be a 16" collar which would give some room for growth as well as comfort for the dog. The 16" collar would buckle at around the middle hole for a 12.5" neck size.
  • For the Angel Rio Martingale style collar, please refer to the respective size chart to find the perfect fit.

Please refer to the Martingale sizing chart below as these collars are measured differently from the Angel buckle collars.

To properly measure your dog for a Rio Martingale collar, please read and follow these steps:
  • The "Fully Tightened" measurements in the chart below refer to the length of the leather straps touching (not including the rings)
  • The "Fully Extended" measurements in the chart below refer to the maximum circumference when the collar and chain are completely opened.
  • The 2 steel rings on either ends of the collar add an additional 1"-2" to the overall length of the collar (depending on the size of the collar as the rings vary in size accordingly). For example, a 14" Rio collar referes to the length of the leather strap, not including the rings.

Measure the middle of your dog's neck, or slightly higher up on the neck, depending on how you intend to use the collar.

* If you want the collar to pinch when the dog pulls, choose between 1.5 -2 sizes smaller than your dog's actual neck size.

For example If your dog's neck measure 16.5", and you want to use the collar to pinch the neck when the dog is pulling, your perfect size would be a 14" Rio Martingal collar. 

* If you do not want the collar to pinch when the dog pulls and simply want the collar to close cofmortably snug around the neck, choose 1 size down from the actual neck size. 

For example If your dog's neck measures 18", choose the 16" Rio collar. The 2 rings on either end will give you an additional 1.5"- 2" length
