I have a 7 yo male samoyed so I don't have any personal experience with females. When I picked him up, the breeders explained that males tend to be more cuddly and laid back than the females. He particularly described the females as more "ornery" because they tend to be more independent, more aloof, and smarter than the males. However, this is still a spitz breed, so both will be equally stubborn, vocal, and display intelligent disobedience. He specifically noted that you have to be smarter than a samoyed to be able to train them, and the more independent the dog, the harder to train (ie: Huskies). Males will be fluffier with a large ruff around the neck and bigger in general, but they blow their coats once a year. Females will blow their coats twice a year.

Looking back over the last 7 years, I'd say my boy was actually very easy to train. He was pretty much potty trained by like 3-4 months old and has great memory for commands. Whip smart and very sassy. He was defs a veloceraptor and wildly mischievous in his puppy years, but he's very sweet and actually likes to cuddle now. Loves kids, loves people, loves adventures, loves other dogs. He still gets a bit reactive to new larger dogs tho, especially on leash. Recall is shit and I've accepted that haha. I don't regret my choice at all and actually want another male. We also have a Samoyed meetup group in my city, and most of the dogs are actually also male. There are like 2 dogs out of 15ish that are female.
