Worming

I succeeded in worming out the secret.

[…] you will need to spend a lot more time training and socializing your Beagle, and must endure the sometimes difficult stages of teething, chewing, adolescent exuberance, and frequent veterinarian visits for vaccinations and wormings.

I think the smaller hook gave better results, with the larger leading to the unappetizing "worming" of chenille.

The other thing you can do is stick with yarns that don't have a reputation for worming.
