Worm Control...
If you read through the 'Tape Worm' post on the main forum then you probably already saw the 'links' below. If not, here they are again.

Do NOT be tempted to use the OTC wormers that are sold for horses, cattle, etc. Even thought the active ingredients are often the same as the ones labeled for dogs, they sometimes have other ingredients that can make dogs sick or even kill them.
My local "Southern States" store sells the 'Safe-Guard' for dogs.
I also use "Interceptor" heartworm preventative once a month and as already stated, it controls/prevents other common parasitic worms including 'Whips'. Does not do anything for 'Tapes' however. There are specific tapeworm medicines but 'Safe-Guard' for dogs takes care of tapes as well. I normally do a routine worming twice a year just for "good measure" (Summer & Pre-Winter)
