Yes, the “colors of the rainbow” site is very old, and was based on guess-work rather than genetics. A lot of it is wrong.

Thanks. Yes, the “choose to heel” video is him.

He is an “ee” clear red (and white, parti) he received an “e” gene from each parent. This is a color, like blue eyes, when, just by looking at the dog, you know the genetics. Because the dog HAS to have two of the genes for the color to express. If he had only one “e” gene, the “other“ color would express. For instance, in he had one “e” (red) gene and one “E” (black) gene, he would have been a black and white dog. (Ee)

Oh, and he also has two copies of the “spotting gene” (SpSp), and one copy of Intensity (In). (I love color genetics! :) )
Is the ‘spotting’ gene belton or something different?

I used to be a geneticist and immunologist. like a hundred years ago in dog time. It definitely could be fun to take a look at the newer DNA.

Ducky is amazing. I also saw a video of him when he was a pup and you were walking around working on his head carriage. I really like the way you work and interact w him
Is there a way to quickly get to other videos u have on this site or a training page or blog u have?
I’ve always had English mastiffs and while the training is the same for about 95 percent there are some differences in training the two breeds to me.
i would appreciate any advice like maybe the best book or something
This was SeaMonkey. He was a 240lb fluffy English mastiff and the last dog I had before I found these amazing dogs.
Although I will probably get another mastiff some day I will never not have a Havanese !!
How long have you been handling them? I’d like to get Mico into agility. He knows his obedience and manners and I think we would ❤ Love it
Thanks

Your mastiff is gorgeous! I’ve always loved giant breeds but don’t know that I’ll ever have one so just love on those big smushy faces whenever I see them 😊

No, the "spotting gene" determines how much white Havanese will have on them. I don't believe ANY Havanese have NO "Sp" gene, which is why even "almost solid" Havanese tend to have a couple of white toes, or a chin or chest spot. The ones with two genes tend to be the loud partis.

Now THIS is a supposition on my part, based on what I know from horse color genetics. But the other piece of how white color is laid down in horses is that it is "switched "on" and "off" by conditions within the womb. That is why you can get horses that are cloned, as is often done with polo ponies, that have markings that are not "identical". They will be in the same general areas of the body, but while one may have a white marking that ends at the pastern, another may have one that goes up to the knee.

I strongly suspect that that is exactly what we saw with the King's identical twin puppies in the spring, who shared a placenta. They HAD to be identical twins, yet one had much more white than the other. But the one with more white, was also much larger than Ruffin at birth. My GUESS is that that puppy got more placental support, which also somehow affected how the white marking gene turned "on" and "off" leaving him with more white than Ruffin has. I thought that seeing these two confirmed twins and being able to watch their development was extremely interesting from the color perspective as well as everything else!

They have not completely untangled the Belton gene yet, and we do not have a DNA test for it yet. We know that it is related to the "roaning" gene, but this gene is not on the same locus in all breeds, so it will take more work to nap it down for Havanese. It will be a good one to nail down, because in its extreme, it IS one that many breeders would rather avoid. (but that is another question... what are the modifiers? a little is fine! LOL!)
Fascinating! Yes, I’d imagine that breeders woud want to detect that one if at all possible. Even though Jolene’s Belton spots are pretty mild, it’s still a very different look than the pure white with symmetrical black spots that she had as a little pup.
