Honestly there are lots of toys out there that are great for beginners, the main things you'd need to look for is something with a tapered tip (like a traffic cone) and has a maximum circumference of less than 7 inches. Other than that, the world is your oyster
If you're looking at equine toys, honestly the same advice applies apart from the tapered tip. Having a blunter tip means it'll be more effort to start it, but other than that you should be fine
