I am sorry to hear about the loss of your dog.
You are just a tiny little speck in a much larger agenda, you simply will not win or get "justice", and will only tire yourself trying, and get no where. In 2010 I literally sold the family farm in Maine where I wanted to retire and was a "when SHTF place" with 30 acres, right off what used to be a "lake", I had a well capped spring, and tiny fish in my streams. I used the money to try to stop what is happening now.
Instead of using man's means, what I and others have done is do something spiritually to delay the wrath of the Creator for a short time. That time to repent is almost up. I will drop you an e-mail to a website so you can maybe wrap your head around what is going to happen and the choice you should make.
Stay safe, stay sane.
