So scary!
I had an incident like this a month ago with Jackson. He was eating some sort of bone-thing he got for Xmas (it looked like a bully stick but was stickier) and he did the same thing-started pawing at his face. After peeking in his mouth and not seeing anything, I just assumed it was in his teeth. But he did it for a good 3 mins and I had to grab hold of him (he kept running from me-I think he was scared) and I finally just stuck my finger in there and pulled out a little piece that had been caught in the top of his throat! So scary!
I did learn about doggie CPR etc when I took my CPR class but honestly didn't remember anything about it. Thanks for the link!
I'm so glad Milu is okay.
