OP here, firstly, there's a lot more to the story than I could fit in 300 characters. The dog that are the blanket is actually my well behaved one. She hardly ever eats anything. She didn't eat the whole blanket. Just chunks of it. She was in her kennel at the time because it's been raining and she's chosen to play in the mud. I'm renting a house with white carpet and I've also had to wash my sheets multiple times in one day due to the mud. So as soon as she comes inside, she goes in her kennel (if she's muddy. If she's not both dogs chill with me). She actually did stop chewing the blanket and started chewing her chew toy. She is a puppy. 7-8 months old, but she's not the hellraiser, the other one is. She was able to poop half of it out on her own, but she was running around with blanket coming out of her ass, trying to figure out what the hell was going on. It was also 11 at night and the area I'm in doesn't have a 24 hour vets office. At this point, I think she's about to start going into her first heat cycle and this can cause dogs to have abnormal behavior. This was a first time thing and it won't be happening again. The reason there's a blanket in the kennels, is because I like my dogs to be comfortable.
