Review on 100% All Natural Pig Ear Strips For Dogs 16 Oz Premium Thick Cut - Inspected & Packaged In USA Rawhide Alternative Pigs Slivers Dog Chew Treats Best For Puppies by Matt Williams

I bought these for my healthy 8-year-old lab mix. DAY 1–After she ate just one, the following day her poop was half black in color. There was nothing else new to her diet that could have caused that change.DAY 2-I gave her another one to make sure it was the pig ear strip causing the change in her poop. IT WAS. The next day her poop was almost all black.I THREW THEM AWAY iMMEDIATELY.Her poop went back to its previously normal color.I would never give her this product again. She has eaten other pig ear brands without this suspicious result.
