Pike and Livers! - Page 5

@ Duke......NO.....Not sure about the Aussie but definitely something other than GSD. 

What breeds carry ticking, and have prick ears, besides AC.

I thought same also. But the dog is DNA tested. Now idk if that is DNA tested because has bred the number of amounts that AKC requires it to be tested or if DNA tested to prove parentage. It is the first panda shepherd recorded and recognized. Aussies have ticking. Ears are not fully erect but not to say that with the GSD influence it could have erected the ears. I myself do not care for them and considering it's supposedly not a Genetic issue it kinda irks my nerves that this dog is being bred. It looks bad on the good in the pedigree simply because people know those names and automatically assume that's where this issue is coming from! What's not known in this pedigree is a mystery as there are no pics or info on the remaining dogs. Just IMO another person Fn up the breed for profit?

Oh, AC I thought Australian Cattle Dog.

 

The biggest argument for the Panda being a spontaneous mutation is that it is a *dominant* trait, not a recessive trait (Irish spotting and piebald factor are both recessive).  If it was a recessive trait due to cross breeding with another breed of dog, the coloring likely would have been bred out within a generation or so. Because it is dominant, only one parent is required to have the gene (white marking) to pass it on, the coloring won't appear unless the parent shows the trait, and if you breed 2 Panda shepherds together, there seems to some problems when a dog is homozygous for the trait (embryonic lethal).

"The Panda Pattern first occurred, as a spontaneous mutation, in a German Shepherd named Lewcinkas Franka Von Phenom (Frankie), in the year 2000. She was quite the surprise to her breeders when she was born. In order to find out why she had so much white, she was taken to Ohio State University Veterinary Hospital. There, her parentage was verified; but the cause of her white pattern could not be definitively determined. The pattern continued to be studied until the causative mutation was located by Mark Neff, Ph.D., a geneticist at UC Davis. The mutation was found on the KIT gene, a gene widely responsible for white patterns, regardless of species; and like many other KIT gene mutations (although not all) the Panda White Pattern is an embryonic lethal when homozygous. This means that pups that are homozygous for the Panda Pattern do not develop in the womb and are reabsorbed very early in the development process. Because this happens so early in development, this does not affect the health of other pups in the same litter or the health of the dam. Panda is a dominant mutation (homozygous embryonic lethal) that can visually look very similar to an Irish Spotting pattern. It causes white on the limbs, belly, neck, and face, with the white being concentrated toward the front of the dog. The front legs will often have white above the knees, while the back legs will have much less, often just on the toes. Blue eyes are uncommon. Dogs with the Panda Pattern not more prone to deafness or other maladies than any other German Shepherd dog." http://colorgenetics.info/canine/white-patterns

Hey YR Hope all is well. I wanted to add to something you posted earlier about Uran. Well he comes down through Canto who was well known liver/blue carrier. I bred a girl years ago and the pedigree had Canto 6-7 and I had one dark sable and the rest were all blue sable. I think he was also a hemophilliac (sp)? I learned all that info un the Malcolm Willis GSD Genetic book. Interesting discussion--thanks for all the interesting posts.

Liver might be a fault but I have to tell you, those dogs are just beautiful!

 

I have two types of linebred Pike dogs: 

3-4 linebreeding

2-3 linebreeding. 

None has produced liver dogs. 

I'm sure they have some carriers in there. And the possibility to produce a liver is high. I would never linebreed on pike!

Why is that?
