This morning I saw the mitten-eating dog with its human at the dog park. The good news is the dog is fine – now. He was running around this morning, having a great time, looking for more mitts to steal. The fellow told me the vet had to somehow pump out the mitt. I didn’t ask for details of the extraction. I’m really glad the dog is OK!

For sure.
It’s good to know the outcome but I find it a little alarming that this is apparently a habit and the dog’s human is oddly complacent about it!
