8 prong Fits 8 1/2" to 15"
Micro Prong collars were designed originally to fit small dogs, because the larger prongs on standard size collars were too far apart, causing both fit and effectiveness issues. A Micro collar is made up of miniature prongs with a much shorter distance between them than typical prong collars.
