Your Guide to Dog CollarsPublished March 3, 2009
Dog collars come in two main types of materials: nylon and leather. When selecting a dog collar, keep in mind your dog's physique.
Here are some pointers:
Dogs prone to tracheal problems, like pugs, are better off with harnesses. Dogs with a thick coat of hair, such as the Shetland Sheepdog, will do better with a rolled leather collar to avoid entanglement. If you want to get a rolled leather collar for a shorthaired dog, that would work just as well. Some collars come with snap closures, which come on and off more quickly. Buckled dog collars are also available and some trainers find these collars to be more reliable. Check the fit by seeing if you can place two fingers under the collar your dog is wearing. However, be sure you aren't able to remove the dog collar over your dog's head.
