I would advise spaying her although honestly it may not help at this point.
How old is the chi?
Sometimes there is just an adjustment period going on. Chi may be letting puppy know...this is HER house...she is the boss. Is she snapping at him or baring her teeth? Those are agressive actions...growls don't always mean aggressive...it's just another way they speak to each other. Ramsey will make growly noises at Reggie the puppy...if she isn't in the mood. It is not the same growl that is a growl of aggression. The only thing that worries me in your case...is her reaction to all other dogs. Are these dogs in her street? That's a terriorial reaction. Mine will do that at dogs walking by our yard.
Shower Chi with attention...letting her know puppy hasn't taken her place in the family.
