It isn't aggression. It's a six month old acting like a normal six month old. A six month old puppy is too big to play with three month old puppies. He's going to mow down the other puppies and it doesn't mean there is a thing wrong with him. He's just bigger, stronger, more coordinated, and more confident than puppies half his age. Choose play mates for him that are of a similar age, similar size, and similar activity level.
Well, there are many types of aggression. American Pit Bull Terriers rank high on dog to dog aggression for example and Rottweilers rank fairly high in stranger directed aggression.
The majority of them do have some level of natural aggression and should not be owned by inexperienced dog owners, but they can of course be trained to be more passive, yes. Ask the breeder to evaluate the puppies and help you select the one least likely to show aggressive tendencies. With proper socialization and training, there shouldn't be a problem.
Shelties are sweet natured dogs who love their owners deeply. They avoid confrontation and are not at all aggressive. They do have herding behaviors (nipping at heels) but that is not aggression and easy enough to stop simply by asking the dog to lie down whenever it does this
Bad owners.
Yes, puppies can accidentally injure or even kill each other during rough play or fights, especially if they are not supervised or if one puppy is significantly larger or more aggressive than the other. It is important for owners to monitor their puppies' interactions and intervene if necessary to prevent serious harm.
In my opinion, Pit Bulls that are dangerous are to be blamed on their owners. Many of them are not raised as part of a loving family. Dogs chained outside that have little interaction, affection and love from their owners can get aggressive. (As with any breed that is neglected) Also, many Pits in the US are trained to be aggressive by irresponsible owners who just want a "tough" dog.I have owned Pits all my life. My dogs have always been part of our family and we have never had a problem with aggression at all.

Chihuahua's have aggression issues because of breeding and socialization. Some chi's are not socialized as puppies. Chi's as puppies are especially small, and a lot of chi owner's don't like their little puppies around bigger dogs. Socializing a puppy means lots of visits with other dogs, children, adults, and taking them out into the world for different sights and sounds. Chi's are very susceptible to injuries, so a lot of owners will limit these visits thinking that they are protecting them...instead they wind up with little dogs that don't know how to handle strange situations. A chi can show aggression when stressed out by a strange dog, person or place. Some aggressive chi's are also a result of bad breeders. Chihuahua's are popular and backyard breeders see this as easy money, and they breed chi's that should never be bred. That's why it's very important to see what a puppies parents are like if at all possible when picking out a puppy. Socializing your puppy with other dogs, people and places will also help with aggression. But remember to keep your puppy safe while socializing.
NO! I have one and it would never kill one of its puppies! it is very protective of one it considers in its closest circle (OWNERS, AND ESPECIALLY PUPPIES).
You will not know until the person has it for a while.
The Kennel Club maintains a list of breeders of puppies of different breeds including Samoyed. It is also worth asking current owners of Samoyed puppies if they can recommend a breeder.
Most pet stores will sell puppies, but if you were to look for beagle puppies only some will carry them. The best way to find them is to ask the pet store owners or browsing in pet stores.
