If a company offered to buy dog food to send them I could see being offended, but here a company that makes a wholesome and nutritious foodstuff intended for consumption by dogs but otherwise better food than many people in the world eat every day offers the food they have on hand to relieve a famine. One answer is a polite "No, thank you". IMHO the correct answer is "Yes, please, may I have some more, please". Should this guy make a decision to cause the death of children because of his own pride?
My opinion may be affected by a personal experience. I was working at a factory in a city I had never been to before. After several hours, I went outside to take a break. Outside the plant I could smell this delicious odor. I looked around and noticed for the first time that the factory I was working at was next door to a Purina plant.
It's not about pride, it's the fact that dog food is just that, dog food. It lacks the substances you find in proper human food. And plus, have you ever tasted dog food before?
