I personally think leaving both males and females but especially females intact for a long time is best for developmental reasons. There are MANY health reasons both ways with a ton of research to read, but from a mental development standpoint, I wait at least three years for dogs I get from breeders, and I don’t do conformation-just performance.
2 intact females can be fine if they mesh well. Less likely to fight than a spayed female, and less likely to have a power struggle than two intact males. Intact male and female-you need to employ some management for unwanted pregnancies, but can be very compatible from a personality standpoint
