Until your last post, I thought these were your rabbits. Are they neighbor's rabbits or wild rabbits? Either way, I take it the rabbits are digging under? You might try digging a 10-12 inch trench along the fence line, staple a mesh wire (like chicken wire with smaller holes) at the bottom of the fence and bury the the mesh below ground. You could also just try pouring small rocks (but large enough to make it too much effort for a rabbit to dig into) in any rabbit holes or low spots where the rabbits are coming through.

If you're pretty sure the tapeworm is coming from the rabbit poop (tapeworm is normally from eating a flea - but can be gotten from eating feces), you'll have to clean it up. Tapeworm eggs can lay dormant for a long time. Once the rabbit poop is gone, your puppy's monthly wormer should kill the worms and even if he eats his own poop, all the eggs should be dead from the wormer.

I stopped my rottweiler from eating "cat cookies" out of the litter box by saturating a "cat cookie" with Bitter Apple and leaving it (on a stack of paper plates) for him just outside the cat box. After tasting a "bitter" cat cookie each day for about 3 days (he went for them, then spit them out), he lost his taste for cat cookies and never even went near the cat box again. (I know, I know "How disgusting"...but it worked!) You could try lacing Jabba's poop with bitter spray...then see if he still likes the taste (some dogs don't get deterred with Bitter Apple).

A cone collar is not a good permanent solution.
