One of ours got ahold of the mesh netting that goes around a pork roast.. Her poop was neatly bundled the next day.
One of ours ate rocks when she was a puppy.. She'd pick up little pieces of gravel or stone, mouth around on it for a second, and GULP.. We mentioned it to a vet who said it was probably a phase, but to watch her as he'd seen dogs come in with bellies full of rocks before. She grew out of it, thankfully.
Like a bunch of others here apparently, we also have a poop-eater.. I actually saw her nom-nom-nomming right from the tap of another of our dogs once. The other dog was kinda hunch-scooting away like "LEAVE...ME...ALONE...!!" That was bad..
Another one at a pint jar of bacon grease...the whole jar. She got really animated a short time afterward like "LEMMEOUTLEMMEOUTLEMMEOUT!!" She went out and made it just a few steps before unleashing something that's come to be known as a case of "the golden arches."
One of our cats -- no access to outside -- threw up *green grass* the other day.. The only thing we could figure is that somebody tracked some grass hay back inside and he ate that, rehydrated it, then puked it up...TADA!
The worst, and possibly most disturbing thing I've ever heard of was my BIL's dog.. Admittedly, this dog hated my BIL's wife, but one day the SIL hauls out a pair of pajama pants that the dog had destroyed and showed them to everyone..
The dog had only eaten the crotch.. The crotch was just
gone...like, a perfect circle had been excised and consumed..
She had sorta anthropomorphized the dog and thought it was just being mean to eat only the crotch like that, but....well, dogs don't really understand pants. As such, they can't possibly understand what part's the crotch and what isn't. My mind immediately ran toward a real explanation for what caused the dog to do what it did, and.....yeah, I'm just gonna stop there because, frankly, having those thoughts pollute my mind once was more than enough for a lifetime..
