Collars come in various materials, the usual ones being nylon or leather. Some collars are made of hemp canvas which is soft and strong. There are organic cotton collars made for smaller dogs. You can purchase a collar with a safety light attached for nightly walks. A prong or pinch collar has blunt-end prongs that fit together and face inward towards the dog’s neck. If you train your dog properly you won’t need this collar. I believe in kinder training methods.
Halter-type dog collars are similar to horse halters. There is a band over the nose and another over the back of the head. The leash attaches to a ring under the chin. Halters give you better control out walking and gently discourage your dog from pulling. Choke chains work well with training. Check with your pet supplier as to how to use the choke chain properly as these collars can cause discomfort or injury when not used correctly.
There is a collar generally used for dogs that participate in therapy, sports and other work. These collars, when it’s necessary to grab your dog quickly, expand into leashes. Flea and tick collars are used only for that purpose, not to be attached to a lead.
Whichever collar you choose, be sure it fits properly. You should be able to slide 2 fingers between the collar and the dog’s neck. If you purchase a collar for a puppy, check the size. regularly as puppies grow quickly.
