TFX had an interesting thread about basically raising dogs in a pack. cant recall an update on how it was going for him. I let dogs go together but it just seems like no matter how much they appear to get along eventually an accident will happen. Could be due to my dogs all being young that I try it with and they are all piss and vinegar. Maybe that's just how MY dogs are naturally. I still keep them together as long as I can. Have two litters I raised together right now and you know which ones can't be with the others pretty soon. It's good to let them experience and learn how to be dogs.
