Terriers are one of the most popular types of dogs around the world. There are seven different breeds of terriers in the top 50 most popular dogs in the world, and this isn’t by chance. Terriers as a group are lively, intelligent, playful, and generally very hardy and stout little companion dogs. They do have their own specific quirks and personalities, just as all other breeds do. Most terriers are relatively easy to care for as far as grooming is concerned but the Yorkshire terrier is a bit of an exception to the rule. Its fine coat requires regular grooming to keep it tangle and mat-free.
