This is a Barbet called Esturgeonne. She has an extremely dense bushy coat. It comes from the crossing of a pure Poodle with what could be another Poodle type. Serienoire, found in an SPA around Paris was most likely a Poodle. We cannot be sure that Lynx was her father as he was not always willing to mate ( information from some private letters I have read).
When selecting partners for matings putting together 2 Barbets with this type of coat will certainly produce a great majority of this type of coat. Basically, you can do nothing with it for it is so dense and so thick, that you have to keep in extremely short as we see some dogs. They cannot have a longer coat than 3/4 centimeters or it gets completely matted. That is non-standard, but perpetrated over the years.
Thelma (open curls) Molly ( tight frizzy curls)
On a positive note, a nice combination is a open curl coated dog with a such bushy type. Then, you will have part of the litter with bushy coats and the other half with looser open curls.
Below, is Duel, as JC Hermans was quoted, he was a Poodle put into a litter of Barbets. Same morphological type.
This is Molly, in 2003. She is from that line. Notice her morphology, dense coat and also the tail that hangs down. The tail as we know is a very important detail, as is the head, when determining a breed.
Very often, the tail is hidden…there’s no “crochet” at the end. It’s also up at 12:10 which is a standard Poodle detail. Or worse…the Portuguese Water Dog tail comes out.Notice how this particular dog, on the right has a very thin head, look at the position of the ears which are quite high and of course the body is rather thin and too long.
Covered in a bushy thick coat…hold the tail down when needed, and voilà.
