The subject of CPR came up over the weekend, and my 11-year-old son asked if it’s possible to perform this life-saving technique on a dog. A little research turned up this excellent how-to video from Pets America. If you have a dog, take a few minutes to familiarize yourself with the steps shown here. Hopefully, you’ll never have to use CPR on your best friend, but if it comes down to it, a little knowledge can be a life saver. And if you wonder about the technique’s effectiveness, check out the video below. WARNING: The video is a bit harrowing, but it has a happy ending.
