Sarah Palin is biting back at critics who blasted her for the Facebook pic of her son standing on the family dog ... and taking a shot at the dog-eating Prez in the process.
Palin took to Facebook Saturday, targeting PETA for bashing her ... calling the org hypocrites that only give passes to celebs who have helped them.
She muses, "Did you go as crazy when your heroic Man-of-Your-Lifetime, Barack Obama, revealed he actually enjoyed eating dead dog meat?" True story, Google it.
Palin accused the org. of celeb worshiping ... then adding they treat doggie Jill better than many people treat human beings.
A rep for PETA tells us, "Palin's Facebook response shows us that she knows PETA about as well as she knows geography."
