There are a LOT of different types of collar out there for your dog. Which one is best for you depends on your dog’s temperament and what you need the collar for. But no matter what collar you choose, make sure it fits! Non-slip collars should be loose enough that you can fit two fingers between neck and collar without choking your dog. Slip collars (including prong and choke collars), head halters, and body harnesses should be fitted with help from a professional.
Buckle Collars
Just like the name implies, a buckle collar is a collar that fastens with a buckle. It works the same way your belt works.
Quick Release Collars
A variation on the buckle collar. A plastic side-squeeze buckle lets you get the collar on easily. This is the type of collar I use on my dogs, for the ease of getting it on and off.
Break-Away Collars
This is a quick release collar with a special release that will break open if the collar is pulled strongly. Invented after a dog choked to death when the collar got stuck on something.
Slip Collars (also known as Chokers or Choke Chains)
A slip collar can be nylon, cotton, or leather — not just chain link! Each end has an O shaped ring, and the collar loops through one of the rings. Traditional training methods suggest using a metal choke chain to correct a dog if it does not obey a command. Metal choke chains can cause neck, back, and throat injuries if used improperly. A heavier chain does not slide as smoothly as a smaller chain, and chokers should never be used on puppies.
Limited Slip Collars
This is an adjustable collar that will tighten around a dog’s neck to keep him from slipping out of his collar — but will not actually constrict the neck. Also called a “Greyhound Collar”.
Martingale Collars
Often used on toy dogs in show situations, this is an adjustable collar without a buckle. A piece of plastic tubing slides along the lead to adjust the size.
Prong Collars (also called Pinch Collars)
These collars work on the same premise as the metal choke collars — a yank to the neck corrects the dog’s behavior. Prong collars are often used on dogs who pull on lead, and should never be used on puppies.
Head Halter
A good alternative for a dog who pulls on lead. These are not muzzles — dogs can still eat, drink, bark, and bite while wearing a head halter. The advantage of a head halter is that your dog’s motion is controlled by (gently) pulling their head where you want them to go — instead of dragging at their neck.
Body Harness
Traditionally used on sled dogs, the harness helps a dog distribute weight while pulling.
