DNA
There is no testing!… like DNA testing!
 

First the Good News: Thor Infante De Gifford is the father of 'the Special one' bred by Karen Carroll in the U.S.A. 
The test is 100 % positive.  Time & again DNA testing is of the up most importance! 

Ask for a DNA test for your dogs every time!  It’s the safe way to avoid all those 'mistakes' like those done in the past by the so-called famous breeders (fake registrations etc. - see on my other site).

Thor Infante De Gifford, like my PWDs, has that rare, ancient and original genetic code seen in the early dogs owned by fishermen, characteristics also found in Vasco Bensaude's (Algarbiorum) early PWDs.

Vasco Bensaude kept an accurate information on each dog born at his kennels in Lisbon - Vasco Bensaude passed on his dogs & his archives to Conchita Cintron - the first to have send her PWDs to the U.S.A. while Vasco Bensaude had refused doing so years earlier... but that is again another story.

The following data sheet is from Vasco Bensaude archives that I had the privilege to read, thanks to my friend Conchita Cintron.  

 Alvor Algarbiorum
 was the result of a
 mating by Leao x
 Murta Algarbiorum.

 Alvor was the only
 white PWD in a litter
 of 6 males and 5
 females - September
 1941.

 Alvor had a white
 coat color and dark
 pigmentation.

 Alvor was given as a
 present to Dr. Mario
 Sousa.

Now, lets go back to those years during the II War when my father took me to Vasco Bensaude's home and I was fascinated by all the dogs, specially by that white puppy!!  White animals have always fascinated me and through the years I owned and bred countless white animals - birds, rabbits, cats and dogs -
first German Shepards and later PWDs.

It’s a long story but, in the end I succeeded in breeding white Portuguese Water Dogs, with that rare and ancient genetic recessive gene, that seemed lost! 

My travels took me to the Algarve and Sezimbra where the first white PWDs had been found. 

Research, breeding and selection with commitment & luck helped me to get "WHITE COATED PWDS". 

I learned, in this long process, that its important to keep in mind,

a)      the standard, written by Vasco Bensaude's vets (see my     site on the subject)

b)     to know dogs genetic background

c)      to concentrate on selection

d)     to avoid inbreeding, in order to get the best result.

To all those interested in white coated PWDs here is a simplified short description of what may be rather complex.

As we know dogs have 78 chromosomes (39 pairs) and each chromosome is composed of genetic material - genes, genes that are referred by specialists with letter (capitals) A, B, C, D, E, G, M, S, T and W - each gene in its series has other genes, mutants, called ALLELES that are situated in gene bases, loci - (sing. Locus).

For example the WILDE color AGOUTI is located in A series (A plus alleles) in A locus.  The same is true for B, C, D etc.

According to some, the white coat color in dogs is

I)       Due to the action of 2 alleles situated in C (full pigmentation) locus resulting in paling or extreme paling (Robinson) & (Little). Inherited as recessive. 

White coat can be also explained by a gene W (whithey), also inherited as recessive. 

II)      White coat color in dogs can also be due to the action of genes situated in S (self colored) locus - extreme piebald (particolor) - inherited as dominant - tested largely at the Jackson Laboratories. 

Most pair of genes are dominant or recessive to each other. 

Coat color & nose leather are polygenetic influenced by different genes and can also be affect by sunlight (the case of winter nose in white PWDs).
