How many different types of shock collars are they?

There are several types of shock collars, primarily categorized by their features and methods of stimulation. The main types include static shock collars, which deliver a mild electric shock; citronella collars that spray a deterrent scent; and vibration collars that use a tactile stimulus. Additionally, some collars offer adjustable settings for stimulation levels and are designed for various training purposes, such as barking control or obedience training. Each type varies in effectiveness and suitability for different Dog Breeds and temperaments.
