Hi.
I am from the Basque Country, northern Spain, forgive my English.

I have a question, until which generation does an inbreeding take effect? until the 5th generation?

Not sure if this is what you mean, but a 5th generation line-breeding (5-5) does not have that much influence. The SV does not allow anything closer than 2-3/3-2 line-breeding though. I generally consider that 2nd, 3rd & 4th generation line-breeding CAN have influence. Beyond that the influence of that particular dog is slight.   However, this can be influenced by the number of times a dog is seen in the 5th generation.  Hope that helps.

Thank you. Yes, that is what he said. The father of my female dog is Gringo JaNaKa and has a blood relationship of 6.6-6 with Troll Von der Bosen Nachbarschaft, the question was whether that blood relationship has influence

Line-breeding is inbreeding by a different name. The proximity of 2-3 being deemed a "red line, albeit one that I've seen some breeders cross in reviewing pedigrees in this site. If done, outcrossing for 1-2 generations with phenotypically desirable (to the breeder's objectives) dogs would be advisable to inject genetic vigor into the line.

IMPO, 3-3 is your best linebreeding combination. 6-6 might reproduce, but more likely to not.
