Breeds in the Terrier group have become more and more popular as time goes on. This has a lot to do with their distinctive looks (many terriers have unique facial structures and unique wired coats) and personality. Terriers also tend to be smaller than the average dog, which is appealing to people with families and smaller living quarters.
They tend to retain their puppy-like cuteness deep into life. If you are interested in a Terrier, make sure that you are aware of the fact that they do not get along well with other dogs, cats, ferrets or other pets. This has to do with the fact that terriers were bred to hunt small animals on farms and personal property (so definitely don't bring a terrier home to a ferret or rabbit).
Terriers are also more difficult to train than the average dog, and aren't normally recommended for first-time dog owners. Well-known terriers include the Bull Terrier, Irish Terrier, Parson Russell Terrier and Norwich Terrier. Lesser known terriers include the Dandie Dinmont Terrier, Bedlington Terrier and Soft Coated Wheaten Terrier.
