What proof do we have that says that dog food is actually the flavor it says it is?!?!

The responses I got-

grxceful-ly - I'm not afraid to admit that I've had my fair share of dog food in my life (lol)

lightning_999 - We have the proof of me the philosopher.

-War_Girl18- - Hazel panics. "FRAAAANK!!"

bookworm100043 - What if they have people to test it? (But the packaging says not tested on humans or animals)   *whispers shadily from a dark corner* how do you know that? How do they know what it's like if they don't taste it? As for what they say on the packaging...*Looks around to make sure no one's there and lowers voice*That's what they want you to think... Sorry. I just love being overdramatic XD ( Lol That actually makes a lot of sense)

lulu_officially - I mean I accidentally tried my dog's food once soooo... (I've tried it too...)
