I emailed key Purina personnel this afternoon and received quick responses from all of them.

The formula is fixed and has not been modified or changed. They use a die in their extruders that produces 9 different pellet sizes. Sizes may appear subtly the same, but when you measure them, they are different.

There are two plants that manufacture MVP.


From one of the Purina guys, "The lot number would be a blue sticker on the bag. The die we use make all 9 sizes at the same time. It would be great to have a picture."

"The lot number (manufacture date) will be on the bottom of the bag along the strip where the tag is and sewn shut."

Snipe, they'd like to see the photos of the tags you have, if you can forward to me, please. Email to boblusk@outlook.com.

I'll send to them. They take quality control seriously, especially since what happened to fish food a few years ago.

Thanks, guys.
