Anonymous call to the SPCA
Lie, or tell the truth, whichever seems best at the time. Or be really honest and tell her you consider what she's doing animal cruelty and if she doesn't stop you will report her. All depends on how strongly you feel about the animal's safety and life
I'd put him in the crate , lock it for 12 hours without water or a bed and say "how does it feel now?"
That person would no longer be my friend. Her greed is repulsive and I would have to remove myself from her presence to resist the urge to exterminate her.
Some people should never be allowed near animals, and certainly should never have pets ! I would take the dog off her and look after it myself.
It's so sad, as the dogs are fine, it's the unscrupulous owners of these so called dangerous breeds, they become a menace to themselves and others. Rather a shame that you cannot euthanize the owners !!!
Offer to look after the dogs. If she refuses that then she needs to be reports for the sake of the dogs. And a dog is not "just a dog". Its a pet you accept responsibilty for by keeping it and in my case its a non voting member of the family.
Animal protection exists to protect animals from people like her.

I'd suggest a new home for this poor dog. I know in the end it is your friend's call, but all animals deserve a good home. And giving them toys, beds, water, anything like that, is the best way to go about it. I wish I had something more helpful, but I hope this works out.
