DDog has had the squits since Thursday morning (been to vet today). We've been being sensible dog owners and giving her small amounts of plain food. Today on our walk she dived into the bushes and emerged with something in her mouth. I panicked, thinking five day old fried chicken or something, and shouted 'No!' She froze, and I retrieved the something from her mouth. It was a donut with icing and rainbow sprinkles 
I threw it away. I have never seen a dog look so devastated. Two hours on and she's still crying on and off. She's lying on the sofa with her back to me. How can I explain?
