For a more accurate fit, measure your dog’s neck by adding 1/2″ -1″ to your dog’s neck size to allow for fur growth and weight. (All numbers are approximate). NOTE: once collar is on dog check for proper fit (tightness) by inserting 2 fingers between collar and dog’s neck, if that feels snug the collar is properly adjusted.
