Oh great....
Known aggressive dog and you are taking her to Lowes and other stores.
Are you kidding??
First off you are putting others at RISK
This dog does not belong at Lowes, other stores, ANY store...she is NOT a 'Service Dog' nor an emotional support dog
She needs licensed training
And you need to stop exposing PEOPLE to injury/danger who have no clue she is aggressive----until it is too late!
And you need to watch her around your wife very closely.
I applaud your commitment to a rescue dog. All of ours have been rescue dogs.
BUT you really need to rethink what you are doing and how you are going about it.
Professional licensed training.....get it.
