A One's Cocker Spaniels

Familial Nepropathy (FN)/Progressiv Nefropati (PNP in Sweden)/Renal Failure/Juvenile Nephropathy -
We keep staggering in a mine-field.

Breeding Rule No 1: make combinations with as few carriers as possible in the first three generations and
NEVER approve of combinations where one carrier appears more than ONCE!

**Samples of renal tissue from one of the latest two dogs have been successfully reprocessed again by the Lees' team
and a definitive diagnosis of FN has been given for that dog! (May 31, 2005)

*2 cases of FN were reported to the UK Cocker Spaniel Club during 2004 (p 25 Year Book 2004) but, for the first time,
the names of the 4 carriers are not published in the Welfare Report (Issue 14 - March 2005). On page 2 in Issue 14 it says
"The Club will publish the names and registration number of all confirmed cases in the Annual Welfare Report.
Parentage will be published unless permission is expressly withheld."

"All animals are equal but some animals are more equal than others." (Orwell, Animal Farm)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The first FN-case was officially reported in the 1930s. Who were the sire and dam? It is not likely that we will ever know which dog was the original mutant.

Was Butterfly of Broomleaf  (blue/roan/tan) an FN carrier? No reports of any of her children dying at a young age. If she was where it all started, or close to it, there wouldn't be enough dogs around which carried the mutation for it to have become apparent in litters within the first couple of generations. The original mutation must have occurred at least a generation or two back from the first recorded affected animals, because of the recessive nature of the problem.  Butterfly of Broomleaf is where the CROSS-OVER between solid and particoloured FN-cases occurred. IF she is an FN-carrier, then it would be reasonable to say that a dog which didn't trace its pedigree back to her would be unlikely to be a carrier..... providing that the pedigree is accurate!

Butterfly of Broomleaf (blue/roan/tan) appears behind both the solids and the particoloured pedigrees that are implicated in the disease. She is the grand dam of Black Friar of Broomleaf, who is the sire of Black Nun of Atway, who is the dam of Atway my Love of Misbourne who is the dam of Valjinxy of Misbourne, Loves Lisa of Misbourne (the grand dam of Perrytree Dark Memory!), Valswytch of Misbourne, Valdoonan of Misbourne, who is the grandsire of Olanza Pipistrelle, grand dam of Broomleaf Bright Memory. Black Nun of Atway is the great grand dam of Bronze Knight of Broomleaf, grandsire of Broomleaf Bright Memory. Butterfly of Broomleaf is also the dam of Broomleaf Black and Tan. Atway My Love of Misbourne is also full sister to Brioche of Broomleaf (grand dam of Butter Candy of Broomleaf, Broomleaf Bright Memory's dam).
Although in the distance, Butterfly of Broomleaf appears to have a heavy influence on the solid FN pedigrees.

Almost every particoloured FN-carrier pedigree seems to trace back to Ouaine Vivid Fairy of Ware, 1952-1964 (SHCH Joywyns Blue Boy of Ware & Merry Flirt of Ware)
She is sometimes 5 or 6 generations back, often a couple more in the distance.
Vivid Fairy is behind Adargi Joyful Girl of Classicway, Leabank Levity, Asquanne´s Niobe, Ouainé Merry Melanie, Bitcon Silver Rebel, Scolys Starduster, Coltrim of Örlidens, Ouaine Half A Dollar, Ouaine Silver Buck, Bitcon Dark Angel, Chrisolin Cambiare of Styvechale, Craigleith Troubadour, Keegans Glory of Coltrim, Harwenprince Evening Star, Deewell Senator, Travis Tribute To Helenwood, Travis Two Tribes, Mossdew Murphy's Law, Hightrees Sweet Talk of Lochranza, Cilleine Echelon, Ouainé Juryman, Ouainé Pandora, Ouainé Piccolina, Hilltops Silver Slipper, Ouainé Panderosa, Ouainé Chieftain, Falconers Envoy Of Ware, Ouaine Chipaway, Ouaine Cherry Blossom, Ouaine Gustav, Merryworth Mr Chips, Ouaine Cherry Blossom, Bitcon Make Believe, Atkia Alibaba, Jette Vom Köhlerwald, Ouaine Guelder Rose, Cochise Commander-In-Chief, Ouainé Gulliver, Örlidens Gay Match, Ouainé Diadem, Coltrim Cactus Flower, Matterhorn Masterpiece, Coltrim Mississippi Gambler, Ouainé Diogenes, Ouaine Juryman, Arclyon´s Aramis of Asquanne, Ouaine Parrandero, Maedown Macao, Britta Vom Riesengebirge, Ezra Vom Rauhen Holz and many others. Show me a particoloured FN pedigree, where she does NOT appear.

Ouaine Vivid Fairy of Ware is half sister to Goldenfields Minstrel Boy, to whom all particoloured FN-cases in the USA trace back.

FN with no exception leads to the death of the afflicted dog. A painful death. To think that it has a genetic component which could be controlled to a degree,
if only there was a better dissemination of information pertaining to carriers of this problem, regardless of who the dog was sired by or was out of,
or how much they had won in the show ring. OK, be defensive when it comes to PRA, HD, or luxating patella. These problems often don't kill or seriously disable dogs,
but FN - there is NO CURE and NO TREATMENT and the dog WILL die! Try telling that to someone who owns just ONE beloved family member! IT IS PURE HELL!
The interests of the breed can only be best served when we all co-operate with each other and ensure that important pedigree information is shared and does not remain hidden away.

This list is NOT intended as an attack on certain dogs and certainly not on their breeders or owners! Nobody is to be blamed!
Unless relevant information is known but hidden.
This page should be regarded as one tool among others to guide you when you are planning a combination.
Which means watching out and not approving of combinations where one FN/PNP carrier appears more than ONCE!
And with as few carriers as possible in the first three, generations. Study the pedigrees and you will find that FN/PNP can (seem to) lurk for a very long time,
it can "skip" 7 or 8 generations ... or can it not? Of course FN can NOT "skip" one single generation!!! It is only the information that is skipped!

There are other types of kidney disease that might also affect English Cockers, but only FN/PNP is inherited.

A mutation based DNA test is up and running and until all dogs have been tested, in a 100 years or so, you are a CRIMINAL
if you do not go public with WHICH of your dogs is a carrier! And accordingly you should be banned from breeding for the rest of your life!
And ... better late than never, so DO IT, NOW!

What if FN is polygenic?

The dogs listed have been the registered parents of animals which have been given a
diagnosis within the diagnostic capabilites of the time:

** The dog died of FN, PNP (Sweden), ARHN, Renal Failure or Juvenile Nephropathy.
* The dog/bitch has produced stock that died of FN, PNP (Sweden), ARHN, Renal Failure or Juvenile Nephropathy.

**Panhur's Amazing Survivor, diagnosed PNP
Breeding rule number 1: NEVER approve of combinations where one carrier appears more than ONCE!

**Shadecock's Nadja, diagnosed PNP September 15, 2005, S21439/2004

**Solbo's Thiffany, blue roan/tan bitch, born June 5, 2003, diagnosed PNP on November 6, 2003
On January 5, 2004, a litter of 8 puppies out of Medeba's Dark Angel-Annie were born and registered at SKK, sired by ... Joycock's Royal Chocolate Love!!!!
And AGAIN, on January 23, 2004, another litter of 6 pups out of Swanmarks Beda were born and registered, sired by ... Joycock's Royal Chocolate Love!!!
AND AGAIN 7 puppies out of Swanmarks Beda were born on June 8, 2005, AND registered at SKK, sired by ... Joycock's Royal Chocolate Love!!!

**Allert's X Models, orange roan bitch born February 16, 2005, PNP diagnosis July 11, 2005

Los Ombues Carol, Spanish bitch, died of renal failure autumn of 2006, born September 24, 2005

FN-case No 034

FN-case No 76

Australia: 3 pups died of renal failure at about 6, 9 and 14 months. The first was not autopsied. The second was, and the diagnosis gave an opinion that the problem
WAS NOT inherited. On the basis of that the bitch was mated again, the second litter born 20 May 2004.
Shortly after the bitch was mated, a third dog from the original litter was diagnosed with renal failure.
Its autopsy said Juvenile Nephropathy, typical of the familial disease of Cocker Spaniels.
A second opinion was sought and 4 of Australia's leading specialist pathologists concurred with the diagnosis.
