Assuming that grooming practices were pre-tested on people before they were used on our Poodles, here's a quick (and very incomplete) review of the history of our grooming tools:

Conclusion: those grooming tools (comb; scissors) which are essential to keep a Poodle in good health and safety pre-date even proto-Poodles. However, those grooming tools (shampoos, electric clippers, and force driers) which are now considered essential to create the sculptured finish, which many admire in today's conformation ring, post-date the initiation and early development of the dog-show movement in the last quarter of the 19th century (see Conformation exhibition): in the conformation ring, technology has driven style. However, it's dangerous to underestimate our ancestors: the late-15th century dog in a Continental clip in a painting by the Master of Frankfurt (1460-1520-c.1533), Virgin and Child..., c. 1496 (Aukland City Art Gallery; see "Gordon's Poodle Visuals") one might take straight off the canvas and into a modern conformation ring without causing the judge to wonder if the revolution had finally come to pass.
It is logical to suppose that the essentials of preserving those dogs who possess tightly-curled ever-growing coats in good health and safety have remained the same since the first such dog lived a long and happy life with the first person responsible for him or her. Here are the essentials:
"Gordon's Poodle Visuals" contains references to a wealth of images of Poodle clips prior to 1900, all but a tiny proportion of which we can't present here without permission from the museums which hold the works of art in which the dogs appear--let alone the books in which the various museums allowed these images to be reproduced. However, old woodcuts and wood engravings are generally "out of copyright" along with the books in which they appeared, and some are reproduced here.
Corded. The earliest images the Poodle History Project possesses (at the moment) are of the corded coat; these include pre-historic statues and an image on an Attic vase (of particular interest to Pulik-fanciers).
Working Continental in days of yore The headpiece for Poodle Lit. 101 (far left; please see that section for the source) probably
comes from a Roman gravestone (stele). A similar clip is worn by a
small dog in a wall-painting at Pompii and also by a small
Poodle/proto-Poodle in a late-medieval bas-relief in the cathedral at
Amiens in France (see "...Visuals"), and in
the headpiece for the Main Menu page of the
Poodle History Project
(1621; near left; please see that section for source). For an early
17th-century grooming manual for retriever work, see Markham.
The editor of the Poodle History Project has found that this historically-correct working-Continental is the most practical clip for field-training, hunt tests, and so on: the dog's legs don't cake with heavy mud, yet the hair is long enough in the short parts to protect against brambles (but doesn't pick them up as hitch-hikers), the dog can swim easily, yet has enough hair in the moderate jacket to keep dry and warm at the skin in cold water and brisk wet windy weather. By contrast, the modern Sporting Clip leaves longer hair on the legs where it gathers heavy mud, and, when wet, the shorter hair on the body curls tightly, leaving skin exposed to cold wind.
On Monday, 27 September 1999, "Castor" CKC CD, JH, WCI, PCA WCX (with his owner, who is also editor and co-ordinator of the Poodle History Project, and with Dr. Stanley Coren, who is author of Why We Love the Dogs We Do -- see Companions to genius...), was a guest on CBC Radio One THIS MORNING and interviewed by famous and venerable CBC host Michael Enright. The subject of the interview was peoples' strong feelings (pro and con) about Poodles and their hair do's. Castor wore his historically-correct Continental clip, the comfortable and functional 2,000-years-old working clip. To buy a tape of this approximately 20-minute interview, please contact Jane Farrow, Producer, THIS MORNING, farrowj@toronto.cbc.ca.
Historically-correct
Working-"Sporting Clip". Markham (1621)
warned our ancestors against clipping a dog down in winter weather (our
ancestors were not restricted by seasons on waterfowl: see Duck dogs--guns and Duck
dogs--traps). The headpiece for Ships...
(at left; please see that section for source) is a late-18th century dog
in an historically-correct "Sporting Clip". Since how-to's of keeping
small flocks of sheep was then common knowledge (just as how to keep
hens was common knowledge in the editor's own childhood), clipping a dog
with a sheep-like coat may have seemed a routine matter. A 17th century
dog in an historically-correct working "Sporting Clip" is shown in the
headpiece for Duck dogs--traps.
(Incidentally, the possibility of keeping a dog year-round in the modern
Sporting Clip is quasi-dependent on the technology of central
heating.)
Entertainment
(performance) Continental (with pompons). Dorothy Macdonald
("Poodles: Past, Present & Future", Poodle Club of America seminar,
1997; PCA videotape) states that pompons in quantity (fancy do's) are a
legacy of use of Poodles as entertainment dogs. Ms Macdonald's thesis
seems very likely. However, Markham's Water Dogge is wearing a pompon,
while Munito, one of the most famous performance Poodles who ever lived
(early 19th century), at left and the headpiece for Circus dogs (for a source, please see that section)
appears not to be wearing his full share: not many pompons on Munito!
Furthermore, John Wooton (1682-1764), in his painting, Dancing Dogs,
shows the diminutive performers, perhaps those very same who danced
before Queen Anne, in an historically-correct working Sporting Clip, and
many of the hunting Poodles sport whimsical poms, for example, Richard
Ramsey Reinagle, in his Poodle and Wildcat (1793), painted the
parti-coloured SP with two bracelets on each front leg, and one each at
the hock behind, plus a pom on the end of the tail, but no hip-poms.
Hip poms are, however, worn in J. Jack's 1867 painting, Parti-Coloured
Poodle on the Beach with a Man's Hat (see "...Visuals").
Evidence in the Poodle History Project's files suggests that hair-do's which preclude accomplishment by the dog, and are, instead, extreme exhibitions of the groomers' skills, are technology-driven rather than performance-driven. This makes sense because dogs who make their families' livings (even comfortable livings) through performance, are not subjected to grooming practices which prohibit this activity. In fact, the exaggerated show-coat which precludes performance is a travesty in relation to historical integrity. Travesty or not, these "grand-opera-clothes" hair-do's are a triumph of skill and, the widespread conviction is, give a good dog the winning edge in the modern conformation ring.
If the first (human) barbers' guild was organized in ancient Rome (see above), we await, with confidence, references to professional dog groomers among those enlightened dog-lovers.
Meanwhile, the earliest image of a professional dog groomer in the Poodle History Project's collection of references is a cartoon: "...coupe chien et chat et son mari..." ("clip dog and cat and her husband"; the cartoon is, almost without doubt, political). Street scene, France ca. 1776, depressed-looking woman, wearing Martha Washington-era clothes, clipping, with scissors, a white Poodle who's holding hind legs straight up and head dangles down hopelessly; sign overhead; two men in knee-britches stand behind (see "...Visuals"). (We have two 19th century images of dog-groomers working on a street; and one of a dog-groomer working indoors.)

See: Mary Elizabeth Thurston, The Lost History of the Canine Race: Our 15,000 year love affair with dogs (Kansas City: Andrews and McMeel, A Universal Press Syndicate Company, 1996), 300 pp. Although lacking annotation (a serious absence, in the opinion of those of us who nearly always like endnotes and footnotes better than the text!), this book contains a modicum of material about proto-Poodle and Poodle grooming, p. 212; the author also mentions 18th century canine stylists; outdoor groomers in post-Revolution France.
1962. Waldschmidt, Kay (pseud. Miss Cameo), The Poodle Clipping Book, over 50 Poodle Styles with Step-By-Step Instructions by Miss Cameo (Jersey City: TFH, 1962). "Most of the Poodles have mustaches. Dedication states: 'This book has been written for, and dedicated to, the Professional Poodle Stylists all over the country, in the hope that it will contribute to the art of styling the Poodle.' There are all kinds of really funny clips here (this is what the book calls them, not patterns, but clips), and includes instructions on coloring your Poodle, and several ways to trim heads and mustaches. The instructions are very thorough, although in some cases out of date, and are indeed, step by step, with lots of illustrations to show what is intended. I was intrigued to read the instructions on coloring the Poodle ('Easter time. ...pink, orchid, green, etc.'). ...in the section [RE] implements for grooming: 'If you have an electric hair drier this is fine for drying your Poodle after bathing. Otherwise, bath towels can be used but your Poodle's coat won't be as fluffy as with a hair dryer.'" (E.LaG., 3/98)
Here's a good beginners' book on Poodle grooming: Shirlee Kalstone, The Complete Poodle Clipping and Grooming Book, 2nd edition (NY: Howell, 1981; first edition, 1968). Unfortunately, the easiest Poodle-clip, the historically-correct working-clothes Continental is not shown except in Markham's 1621 illustration (p. 7 and above).
Headpiece: This English Saddle clip is "legal" in conformation rings in Canada and the United States, although the exaggerated technology-driven Continental clip is most often seen. Here, AKC Ch Litilann's Absotivly Rosie is shown winning Best of Variety at the Westminister Kennel Club's show (widely televised annually) in February, 1996. All dogs exhibited at Westminster are "Specials" and the specials coat is very much so! Rosie was Breeder-Owner-Handled to this big win by Ann Rairigh. The English Saddle is a more difficult trim than the Continental. Nevertheless, just as the Continental's "historically-correct working-clothes" version is permissable in today's conformation ring, the English Saddle can be rendered in a workaday version which is allowed. You may wish to experiment to see if the English Saddle becomes your Poodle. A third clip is permitted: puppies under a year also may be shown in a puppy-clip (the most difficult clip of all--so if you're an entire newcomer with a yen to practice...). A knowledge of Poodle history will give you the courage to groom your own dog just as Poodle and proto-Poodle owners have done for many hundreds of years (with less equipment than's available to you!). Don't be intimidated by modern "big hair" fashion which is not required by the breed standards. Along the way, don't miss the fun of exhibiting your dog in the conformation ring; start with a match. Set your goal: by doing, to learn as much as possible about conformation and its exhibition; that way, you're guaranteed to win, albeit on your own terms.
