Do dogs sometimes hold things they cannot digest in their stomach for days, like a cat holds onto hair where it forms a hairball? Has anyone heard of this or experienced it with their own dog?

Today, after a delay in getting to eat, Moses came to me when I entered my kitchen and started vomiting. My son Mike said to examine it because it looked strange...and if you don't like ucky, don't read anymore. It contained colorful pieces of plastic, maybe small pieces of paper, pieces of unidentifiable things, long hair bound around and through the mess holding it together in two or three masses, which I had a hard time examining. He wretched once more but there was nothing else. I have been watching him today, no further signs of stomach upset, he has eaten (though I gave him half the usual), drank lots of water, so I'm pretty sure he doesn't have a blockage.

My dog likes chocolate, and likes to chew on things although usually only his toys, but lately my granddaughter's small toys. Even outside his nose if always to the ground. My other dog Sandy brings me things all the time that he's picked up in the house, since we have a full house with my oldest son and granddaughter now living with us.

AGAIN, I have to talk to him about the safety of my pets.

Dog toys have been checked and many thrown out, but no plastic in them. Granddaughter's toys out in the back porch. Moses could not have gotten into anything today, nor yesterday, for sure. This stuff has got to be from before.

I worry it will happen again. Ever heard of the stomach retaining debris not digestible?
