Why is soda bad for dogs?

Soda absolutely has to be bad for dogs if it's bad for humans! You can buy some that doesn't have any corn syrup in them or other certain "unhealthy things" but still, why would you want to make a dog sick if he's part of your family? Did you know there's high fructose corn syrup and a lot of sugar? Sugar is linked to diseases. It's very acidic. I don't give my dogs anything but organic dog food and some home cooked meals without anything added to them. Please don't give your dogs soda...
