Howie and the frog's arm

Yesterday as I was drinking coffee in the kitchen, I heard the familiar throw up sound from the dining room. I saw Gordy in front of me, so I knew it was not him throwing up... I was worried because Howie the dog never throws up... He was hovering around a 5" object... I made him leave it and he ran into his crate to hide. I thought for sure he snagged something and ate it. He threw up the arm of his soft frog playtoy. What was wierd about this? I threw out the damaged being last week! He had that stuffed toy arm in him stomach for a week? I'm sparing you the photo... It was a green arm covered in stomach juices. He's fine now. I'm sure the next time I hear the throw up noise it will be Gordy the cat. Again.
