When we adopted our puppy Sophie from the pound last year she tested positive for Giardia (a parasite) and we prescribed antibiotics to treat her. Instead we did the parasite cleanse as described for pets at:

.. and I'm really happy to say today that a retest has shown that she is parasite free.

It could have been the cleanse, or it could have been finally having a home with real raw non processed food, either way it's great that she is clear. Just in case anyone else is in the same position I wanted to share.

Cheers,
Sheryl
