Size Guide

Welcome to our Size Guide! We created this page help you find the most ideal collar size for your pet. Keep in mind, all collars are made-to-order and sales are considered final. Please don't guess your pet’s measurements!

To ensure your pet's safety, never force a slip-on collar over that is too snug, and please make sure you've used a soft tape measure accordingly with the instructions below.

Any confusion? Send us an email with any questions or to confirm sizing. We’re happy to assist! hello@hypnoticdog.co

Slip-On (O-Ring) & Martingale Chain Collar Size Guide

Slip On (O-Ring)
Martingale Chain

Instructions

  1. Measure the widest part of your pet's head snugly with a soft, flexible measuring tape.
  2. Widest part of your pet’s head is typically in front of their ears, in the middle of the head. Do not pull so tight that the fur bows out, but also do not add fingers or extra space between the tape measure and fur.
  3. If your pet has larger neck than head, select the larger measurement to ensure a comfortable fit. This should be where you expect collar to lie, generally in the middle (not at the base).
PRO TIP: Mimic sliding the tape measure over their head to ensure the proper fit!

***IMPORTANT: If you are using a body measuring tape that inserts back into itself (it has push button retraction and a ‘handle’ housing the tape) this must be used accurately. These body tape measures are to be inserted back into itself around your pet’s head/neck. If used correctly, it should be hands-free measuring on your pet. Do not attempt to use it like a soft flexible measuring tape as these typically begin at 2” to account for the tape measuring housing.

*Please do not use a hard measuring tape.
*Please select the head measurement as measured. We accommodate for the size of the beads and attachments on our end

  • Most popular style
  • Hang ID/tags
  • Suitable for loose leash walking pets due to slip-on nature

  • Sizing is most important for Slip-On styles as the only way it is going on and off is by sliding on and off your pet. Please triple check measurements for a safe fit that is not too loose nor too tight. The neck measure where you want the collar to lie should always be selected if it's larger than head.
  • *Please note, while black hardware is by far our most popular & repeat selected option, the black is powder coated vs plated and may be subject to quicker wear & tear vs the other plated collar options.

Considerations:
  • Similar to flat styles (fabric, biothane, etc) of collars, for safety we recommend always taking off collars during play, when crated, and whenever your pet may be unsupervised.
  • Please measure your pet as outlined in the size guide and do not guess, to ensure the collar is neither too tight nor too loose.
  • Although tightly strung, these collars are best suited for short hair breed dogs.
  • Martingale chains across all materials can show discoloration on lighter-colored fur.
  • Please note: Topical flea and tick meds interact with our sealed wooden beads and acrylic beads; we do not recommend wooden or acrylic bead styles for those who use topical flea/tick meds on their pets.
  • Please see our FAQs page for additional common questions & answers regarding our products, different bead styles, etc.
  • Bead Sizing: Jumbo -> Regular -> Mini -> XS beads from biggest to smallest; please reference photos and description within listings for bead sizing.
  • Small dog breeds such as chihuahuas and pomeranians that have small mouths and shorter necks, we STRONGLY RECOMMEND to select the buckle style for a snug fit around the neck for safety.
  • Our ceramic, resin, and semiprecious bead selections are our most durable options due to material hardness.
