I was at the vet's the other day and they were treating a Labrador for
this
parasite. It supposedly comes from the dog drinking from a natural
waterway
where "infected" flukes were present. My fish have never had flukes, but
I
wonder if it would hurt our neighbor's dog if he drank water from my pond
and they actually had a case of them before I knew of it. Flukes are bad
enough, but "infected" ones? I wouldn't worry about it, but it just made
me
wonder because he is such a nice dog.

Giardia is a problem in any waterway where animals have defecated in or near
the water. It's a common problem for backcountry hikers. It's the main
reason many hikers, filter their water. Many hikers joke about going on the
Giardia Diet, in which no matter how much you eat, you lose weight because
you are unable to digest anything. LOL.
