Working from home I bonded quickly with them and doted on them like they were my own children.
I see this as the major problem. They had no respect for humans and reacted to your daughter as they would to another dog.
Instead of respect and knowing who was in charge.
I don’t know that the situation can be improved without professional training for the dogs.
Unless and until that happens, you must be certain that neither the dogs nor the cat can get near your child, especially when you are your husband are not around.
I have two dogs that I love dearly. Our children are grown and gone, but we have a passel of grandkids, and if I were worried about the dogs harming them when they are visiting, I would immediately find another home for the dogs.
Since they are both Labradoodles, they are very child friendly and do not possess a vicious bone in their bodies, but I still make sure they are closely supervised when the grandkids are here.
There’s no point in beating up on the poster for any mistakes in the past. She has suffered and questioned herself quite enough.
