So,so glad Krypto is okay! I never knew for sure what caused Chelsea's last year after Christmas, but I did have to take her in to the vet. I suspected a piece of brownie, because that's all I could really think of that she'd gotten, but she couldn't even get out the doggy door. She hated it, we could tell, but she had no control. It's so hard when they are sick and you don;t know what's causing it. I'm so glad he is ok!!
