Realistically it seems unlikely one could retrieve a weapon when the attack is happening unless it’s on your person. We just don’t walk around our backyard with weapons at the ready.
Better IMHO is to forewarn any neighbor with a pit bull that should an incident take place with a loved one or loved pet, they will pay the price and not with $$$$.
She could've easily retrieved a firearm from her house (if she had one) while her husband was fighting with the dog.
We used to have a neighbor who would let their pitbull run free at the exact moment I was leaving the house to take my small children to school.
It usually went straight to our yard, which always made me very uneasy.
I always went outside first to recon the yard.
I never let the kids go out there without doing this until they moved away.
I am so glad they’re gone.
