Ol' Roy dogfood 2012

Ol Roy dog food (of all types) is killing cats and dogs. (I lost five dogs and one cat) Mine came down sick and died within 2 weeks of my husband buying the food. I realize you get what you pay for but come on. It's killing!

Symptoms:
At first extreme thirst, pain after drinking, and then within a few hours, no want to drink at all.
Thick foam vomit that stuck to the sides of the mouth.
Purple coloring on stomach.
First, sheer blood coming from bowels on some,  on others only watery looking blood leaked out it seemed without their knowledge.
Wouldn't stand. Legs got stiff. Wouldn't even blink. (I am assuming from shock here?)....
And right before death it appeared they had a seizure.
Vet care did nothing.

We can't allow this company to continue. Please help me!
