I actually had to give the Heimlich to my dog a few months back. She somehow inhaled a big piece of dog cookie, and started running around gasping. I could tell she was panicking, and then I started panicking too! I just remembered seeing how to do it on humans, so grabbed her underneath her belly & felt for where her ribcage met the soft part, and put my thumbs there and pulled up. After a couple of pulls she got the cookie up! It was super scary but she turned out fine.
