I think there are times when a young dog (or any aged dog) shows being overly submissive, other dogs will take advantage of that. Whereas Kira may not be a totally dominate dog, this puppy gave her the position no questions asked. Removing Kira was the right thing to do.
I think when even a normal, confident dog is around overly submissive dogs they learn to be dominate and even bullies. To me, that is just a dangerous as letting your dog hang around overly dominate dogs.
