What do you mean by "bad" color? If you mean what are the chances that you will produce a trindle, which is a natural result of having brindle and tri in our genepool, it depends on the parents.
If the brindle parent does not carry the tri gene then there is a 0% chance of producing a trindle.
If the brindle parent does carry the tri gene then there is a 50% chance of producing a trindle.
But without knowing who are tri carriers and sometimes people can be quite surprised when what they thought was their pure for dog produces a tri there is always a chance that you may get trindles. A tri carrying brindle bred to a tri carrying red has a 12.5% chance of trindles.
HI thanks for your reply
with "bad"colour I do mean not recognised colours, in this case trindle indeed, I put it between "" as I dont think the colour is bad in a bad way but just not recognized, ehhh still following me?
the fact is that my male has been asked for a brindle, my male comes from tri x tri mating and the female I dont know yet, I asked them to send me a copy of the pedigree, when they have done that I can tell you about her parents etc, and maybe you can tell me again what the chances are. As people in the netherlands always say not to mate a brindle with a tricolor because of the possibility of trindles, but I am not sure if that is always the case… still following me in this also? ( I feel stupid now )
I do follow you and I think things in the US are very different then other countries. In the US, a good quality trindle is finishable and in fact one just finished their championship this past weekend in West Virginia. Also, AKC has told the fancy that trindle is, in their opinion, covered in our standard.
The big no, no for those who do not want to produce trindles in breeding a tri to a brindle is not just that you may produce trindle offspring in that breeding but also that every brindle offspring in that litter is capable of producing trindle if bred to a tri carrier. The problem with this way of thinking is that the ONLY way to be sure you don't produce a trindle is to never breed a brindle because the recessive tri gene can hide for generations.
that the recessice tri gen can hide for generations is known to be, I know of bri x bri and bri x clear red/white matings that were supposed to come out of clear red/white and brindle lines for severall generation produced tricolors and trindles.
Look on Sally's database, we were asked too for the same bitch with Buana as stud (well, I think it's the same brindle bitch)
I found the pedigree on Sally's database, maybe you know a little bit more..
There is a lab in the US that can do a DNA test and see whether or not a dog carries the tri gene. I'm not sure how accessible this test is for foreign dogs, but I think it's around $75 here to get a dog's color tested just for that part.
So if a breeder is really that worried about it, they could look into testing. Otherwise, then just go with the best breeding choice. Color is of such little imporance anyways to the function of the breed.
In the US, we were told by AKC that Trindle is an accepted color because they are black, tan, and white. Our standard does not describe what pattern these colors are supposed to be in so as long as there is clear demarcation between the black and tan on the dogs then in AKC's opinion they are well described by our standard.
Here is a website with a picture of a trindle where you can see his stripes. Some will be more heavily striped than others just like with brindles.
The ones I've actually seen in person, on the face, their red looks more brown and muted because of the brindling. The one in this pic still looks red and the markings seem clearer that what I've seen in person.
It really depends on the brindling. I have seen several that look like Tazi, I have also seen some that look like the one in picture Petra posted and ones that are in between. I have also seen a couple where if you can't find the single stripe that they have in the tan you would never know they were trindles.
I like the pic of Tazi because there is clear demarcation between the black of his stripes and his tan which is what the standard describes.
