Dogs have some pretty drastic differences with not only coat lengths, but also their coat types. Here are the different coat types found in many popular dog breeds.
Wire Haired dogs like the Scottish Terrier, Irish Wolfhound, and Jack Russel feature unique slow growing coats that require moderate upkeep and maintenance. Many wirehaired breeds are characterized by their “mustaches” or “beards”.
Silky coats like those of the Afghan Hound, Lhasa Apso, and Yorkshire Terrier are characterized by long flowing coats that require far more work than many breeds. In fact, these breeds require some of the most labor intensive upkeep to mitigate mats and tangles.
Curly haired dogs, like Poodles, Doodles, and many different terrier breeds feature low shedding and relatively easy to manage coats. Many of the Doodle mixes take advantage of this desirable trait by mixing their coats into other popular breeds.
One of the more rare dog coats is the corded coat found on Komondors, Hungarian Pulis, or Bergamascos. Corded coats resemble dreadlocks and can often be misattributed to neglect or abuse. Although these coats do not need brushing, they still have pretty high grooming requirements compared to many other breeds.
