Lola Secret Powers Micro Prong training collars were designed originally designed 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. Micros are especially good for larger dogs with short, sleek coats, as standard sized collars tend to slip down on slippery fur.
