Samoyed dogs and Smooth Collie's are both what type of working dogs.
herding
Smooth Collie
The Smooth Collie is a breed of dog developed originally for herding.
 It is a short-coated version of the Rough Collie of Lassie fame.
 Some breed organisations consider the smooth-coat and rough-coat dogs to be variations of the same breed.
Samoyed (dog)
The Samoyed ( or ; Russian: Самоедская собака or Самоед ) is a breed of large herding dog, from the spitz group, with a thick, white, double-layer coat.
 It takes its name from the Samoyedic peoples of Siberia.
 These nomadic reindeer herders bred the fluffy white dogs to help with the herding, and to pull sleds when they moved.
 An alternate name for the breed, especially in Europe, is Bjelkier.
Farm collie
Farm collie or farmcollie is an informal term for a class of herding dog, of the broader collie type.
 Farm collies are bred for more than looks; working dog traits, including cleverness, loyalty, and hardiness, are sought.
 Farm collies are also common household pets, and sometimes trained as guide dogs for the visually impaired.
 The term "farm collie" can have various meanings, including: Dogs with Jobs
Dogs with Jobs is a Canadian documentary television series about working dogs and show dogs. Each half-hour episode consists of two to three segments on individual dogs from around the world.
 The family-friendly series has featured service dogs, search and rescue dogs, police dogs, herding dogs, and others.
 Segments show footage of dogs on the job, and also include stories of their rescue, training, and relationships with their owners and handlers. Mist: The Tale of a Sheepdog Puppy
Mist: The Tale of a Sheepdog Puppy is a British family television film following the life of a border collie puppy as she grows up to become a working Herding dog.
 Part fiction, part documentary, it was filmed by real-life shepherd David Kennard on his farm in Devon.
 It features his seven working dogs - the puppy Mist, her gentle mother Gail, grandfather 'Sir' Gregory, eccentric, bubbly, hyper uncle Jake, sour and negative great-auntie Fern, gruff, tough cousin Ernie and wise auntie Swift. Collie
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. Scotch Collie
The Scotch Collie is a landrace breed of dog which originated from the highland regions of Scotland.
 The breed consisted of both the long-haired (now known as Rough) Collie and the short-haired (now known as Smooth) Collie.
 It is generally believed to have descended from a variety of ancient herding dogs, some dating back to the Roman occupation, which may have included Roman Cattle Dogs, Native Celtic Dogs and Viking Herding Spitzes.
 Other ancestors include the Gordon and Irish Setters. Koolie
The Koolie (also known as the Australian Koolie or by the misnomer German Coolie) is an Australian dog breed.
 The Koolie is a working or herding dog which has existed in Australia since the early 19th century when it was bred from imported British working dogs.
 Robert Kaleski, in an article on Cattle Dogs in the August 1903 issue of the Agricultural Gazette of New South Wales, describes the "Welsh heeler or merle, erroneously known as the German collie," as a "blue-gray dog about the size and build of a smooth-haired collie, generally with wall eyes."
 The British background predominated in the dogs that came to be associated with the "German collie" name. Samoyed hereditary glomerulopathy
Samoyed hereditary glomerulopathy [glo-mer″u-lop´ah-the] (SHG) is an hereditary noninflammatory disease of the renal glomeruli, occurring in the Samoyed breed of dog.
 The disease has been shown to be a model for hereditary nephritis (HN) in humans in that the disease resembles that of the human disease.
 Because of this, it is sometimes referred to by the name given to the disease in humans when referring to the conditions in Samoyed dogs.
 Alternatively, it may also be known as X-linked hereditary nephritis.
 Genetically, the trait is inherited as a sex-linked, genetically dominant disease, and thus affects male dogs to a greater degree than female dogs, since males only have one X chromosome. Perianal gland tumor
A perianal gland tumor is a type of tumor found near the anus in dogs that arises from specialized glandular tissue found in the perineum.
 Perianal glands do not exist in cats.
 It is also known as a hepatoid tumor because of the similarity in cell shape to hepatocytes (liver cells).
 It is most commonly seen in intact (not neutered) dogs and is the third most common tumor type in intact male dogs.
 There are two types of perianal gland tumors, perianal gland adenomas, which are benign, and perianal gland adenocarcinomas, which are malignant.
 Both have receptors for testosterone.
 Perianal gland adenomas are three times more likely to be found in intact male dogs than females, and perianal gland adenocarcinomas are ten times more common in male dogs than females.
 The most commonly affected breeds for adenomas are the Siberian Husky, Cocker Spaniel, Pekingese, and Samoyed; for adenocarcinomas the most commonly affected breeds are the Siberian Husky, Bulldog, and Alaskan Malamute.
