astounding polka dot dog collar collars are like flat collars but they tighten when the dog pulls. Even though they tighten, they are generally not used for giving a correction the way a choke chain is. Rather, they are used because they are less likely to slip over the dog's head when adjusted correctly than a flat collar is. These collars should be adjusted so that even at their tightest they cannot accidentally strangle the dog.
So there you have it, an overview of a variety of common collars and harnesses. None is perfect. They are all just tools. But some are more likely to cause problems in your pet or may just provide a less than ideal match for your needs. In case you're wondering which I prefer—ideally my dog can walk on leash with the flat collar he wears regularly. But for those dogs that tend to pull and need more work, I tend to recommend a front-attaching harness or a head collar of some sort.
