I agreed with Debbie, noisy toys and stuffed animals seem to be the ones that Gucci likes. She also likes the rope. You say that you don't want to give them a rope in fear of them breaking free the thread on the ends and swallowing them. What I do is to check all of her toys and if it is loose or broken i try to repair it or I replace it. I heard the ropes is like dental floss to them. At least my Gucci loves hers. My Gucci used to chew on my furniture, i tried the sour apple but didnt work. I kept telling her NO and gave her a chew toy. I dont know if that work or she just grew out of it. LOL. At least you know there is hope. Good luck.
