I used to work for Hartz Mountain and one of the scientists
came around one day handing out "cookies". They were
dog treats and they tasted just like animal crackers.

my Grandmother once bought one of my cousins a snack treat she found in the store. They where called People Crackers, not knowing what they really where(1970's probably about the time they first came out).

in processing and packaging human foods.

I once worked at the pet foor manufacturing arm of Quaker Oats (as a Manpower temp). The processing of pet foods was quite careful.

On edit: I bet a lot of people here either ate Milkbones or other such pet treats or had siblings or cousins who did.

I knew that one of my cousins would sneak small Milkbones when her mother wasn't looking.

our dogs' Milkbones. They tasted good then.

(Milkbones are made here, I believe.)

Some food companies, like Quaker Oats, have subsidiaries that make pet foods and treats.

Only the original milk bones are made here,the rest, China. If you go through the dog food aisle, you will see distributed by, And a few marked Made in USA. If they don't say it,it means they are not made here, it is a selling point now, so if they could they would. Milk bones says the original are made here, but they don't mark it because they could only put it on one type only.
I know, I check. I have called numbers when they say any questions, they can never say outright they are made here, so they are not. I am trying to embarrass them to move back,but right now I would give a lot if they would mark Human food that way,I know that my medications are made in China and Vietnam. They won't tell you, but you can find that information when you query them individually.

Neighbor lady paid us to walk her dog and we swiped a few of his treats. Not bad, kind of tasteless.

Not much taste.
