Technically, no, they arent. That said, I know of a litter where two of the male dogs just cant seem to get along! Sometimes in a litter the puppies will keep getting into fights because they are trying to figure out the pecking order. They want to know who is the top dog! So they will get into little fights because they are growing up and trying to figure out their place in the world. What can you do? Having the dogs spayed or neutered does help stop the aggression. Also, you might have to just be patient and wait until they grow out of it. That should happen when they are around 2 yrs old. (a long time, I know.)
Good luck!
