Yes - had a 10 yo choke on a brisket bone and virtually die. She was blue and not breathing. It was horrible. I managed to reach the bone and push it sideways and air was released. Then hubbie managed to get his hand down her throat and pull the bone out after my 3 attempts had failed. Then heart massage and compressions and she coughed and then started breathing. It was the longest 5 mins of my life. I saw her go down and was with her for her frantic last attempts to breath... That was two years ago and she is still in brilliant health, but I am very careful now not to feed bones to older dogs or greedy gulpers. It was just so lucky that I was able to get there within seconds that day, hubbie was home,and we started working on her immediately. Another dog had woofed 'funny' and that made me look out the window. Another minute would have been too late.
