I had 3 females, all 3 years apart, 2 older ones not spayed, the 3rd spayed, none related, there was never a growl, snarl no kind of aggression. They ate lined up, slept and played together. Only thing I can think of is the momma getting spayed and the aggression started, momma may have a dif. smell that the daughter does not recognize. When I had the puppy spayed my vet told me to be careful when she came home, he said the two older dogs may not recognize her scent, he said the pup would be coming home with dif. dog smells on her from the dogs being held over, just a thought on the recent aggression. Hope you can work this out.
