hang/suspend a dog. They are used as "corrective" tools despite dogs having no concept of "good" and "bad". Footage of this collar being actively used typically shows a dog with common signs of discomfort(ears pointed back, lip licking, raised eyebrows and "stress lines" on the face) At times, plastic tips are occasionally placed on the ends of the prongs to protect against catching the fur and pulling tufts, or in the case of low-quality collars with rough or chisel cut ends, irritating or perhaps puncturing the skin. Its important to examine the tips of the prongs to ensure they are rounded and smooth regardless if they have rubber tips so that they only cause discomfort and no visible injury. Like any collar the prong collar can fail if the dog has not been put into a state of learned helplessness. Some dog training organisations will not allow members to use them, and they are prohibited by law in Victoria, Australia. Force collars Force collars are leather with metal prongs or studs lining the inside; similar in effect to prong collars. Choke chains Choke chains (also called choke collars, slip chains, check collars, or training collars) are a length of chain with rings at either end such that the collar can be formed into a loop that slips over the dogs head and typically rests around the top of the dog's neck, just behind the ears. When the leash is attached to the "dead" ring, the collar does not constrict on the dog's neck. When the leash is attached to the "live" ring, the chain slips (adjusts) tighter when pulled and slips looser when tension is released. Training with this leash involves a quick jerk with an immediate release, called a "leash pop", "snap", or "correction". This is supposed to correct a dog's unwanted behavior, such as leaving the "heel" position. Pulling harder or longer on the choke chain presses on the dog's trachea and/or larynx and may restrict breathing. Cesar Milan's "Illusion collar" is a choke collar wrapped in a buckle collar. Fur saver collars Fur saver collars are a kind of slip chain that contain fewer and longer individual links than a close link chain, also known as a long link fur saver collar. Fur saver collars can be used both for long and short-haired breeds limiting damage to the dog's fur. It can be used for training and
