Sam (November 7, 1990 – November 18, 2005) was a blind pure-bred Chinese Crested hairless and toothless dog, and three time champion of the annual Sonoma-Marin Fair World's Ugliest Dog Contest in Northern California in 2003–2005.
 His ugliness gained him international fame and celebrity – his death was a top headline on major news websites.
The Sandwich tern ("Thalasseus sandvicensis") is a tern in the family Laridae.
 It is very closely related to the lesser crested tern ("T. bengalensis"), Chinese crested tern ("T. bernsteini"), Cabot's tern ("T. acuflavidus"), and elegant tern ("T. elegans") and has been known to interbreed with the lesser crested.
The Chinese crested dog is a hairless breed of dog.
 Like most hairless dog breeds, the Chinese crested comes in two varieties, with and without fur, which are born in the same litter: the Powderpuff and the Hairless.
The Black and Tan Virginia Foxhound is an American foxhound breed.
 It resulted of a cross breed with Bloodhounds in the 1700s.
 The breed was developed by the landed gentry in order to get a dog suitable for fox hunting.
 Besides the Black and Tan there are the Walker, Calhoun, Penn-Marydel, Goodman, July and Trigg, which all developed from similar crosses.
 The Black and Tan is believed to descend form hunting dogs imported to America by Robert Brooke in 1650.
 These hunting dogs were the ancestors of several varieties of American hounds and stayed with the Brooke family for more than 300 years.
 Afterwards French Foxhounds were bred in after George Washington received them as gifts from the Marquis de Lafayette.
 Much later, the breed's speed and stamina were improved introducing Irish Foxhounds.
The Chinese crested tern ("Thalasseus bernsteini") is a tern in the family Laridae, closely related to the Sandwich tern, "T. sandvicensis", and the lesser crested tern, "T. bengalensis".
 It is most similar to the former, differing only in the bill pattern, which is the reverse of the Sandwich tern's, being yellow with a black tip.
 From the lesser crested tern, which it overlaps in wintering distribution, it can be told by the white rump and paler grey mantle, as well as the black tip to the bill, which seen from up close also has a white point.
 The larger greater crested tern is also similar, differing in its stouter, all-yellow bill and darker grey mantle and rump, as well as in size.
The Black and Tan Coonhound is a breed of dog.
 Developed in the United States from crosses between the Bloodhound and the Black and Tan Virginia Foxhound, this coonhound runs its game entirely by scent and is used primarily for coon hunting.
Miss Ellie (c. 1993 – June 1, 2010), a blind American Chinese Crested hairless dog, was the 2009 winner in the pedigree section of the World's Ugliest Dog Contest.
 She appeared in shows at the Comedy Barn in Pigeon Forge, Tennessee, and was featured on the Animal Planet cable show "Dogs 101".
 Dawn Goehring rescued Miss Ellie at seven years old.
 Miss Ellie died on June 1, 2010, at age 17.
Follicular dysplasia is a genetic disease of dogs causing alopecia, or hair loss.
 It is caused by hair follicles that are misfunctioning due to structural abnormality.
 There are several types, some affecting only certain breeds.
 Diagnosis is achieved through a biopsy, and treatment is rarely successful.
 Certain breeds, such as the Mexican Hairless Dog and Chinese Crested Dog, are bred specifically for alopecia.
The collie is a distinctive type of herding dog, including many related landraces and standardised breeds.
 The type originated in Scotland and Northern England.
 The collie is a medium-sized, fairly lightly built dog, with a pointed snout.
 Many types have a distinctive white pattern over the shoulders.
 Collies are very active and agile, and most types of collies have a very strong herding instinct.
 Collie breeds have spread through many parts of the world (especially Australia and North America) and have diversified into many varieties, sometimes with mixture from other dog types.
 Some collie breeds have remained as working dogs, used for herding cattle, sheep and other livestock, while others are kept as pets, show dogs or for dog sports, in which they display great agility, stamina and trainability.
 While the AKC has a breed they call "Collie", in fact collie dogs are a distinctive type of herding dog including many related landraces and formal breeds.
 There are usually major distinctions between show dogs and those bred for herding trials or dog sports.
 They typically display great agility, stamina and trainability and more importantly sagacity.
