I bought an everlasting treat ball for my little Morkie. She really had fun playing with it at first. Then thank heavens I was in the same room with her as I heard her choaking and checked her mouth. She had a fairly good sized piece of the rubber from the treat ball in her throat. I was able to reach my finger in and scoop it out. I gave her the treat thing to chew on until it got to small then I threw the whole thing away. Be careful if you have a chewer!
