We've been boarding an elderly relative's dog for the last couple of months. I took the dog to a farm this morning where the pond is filled with "pond scum." This dog has never once been in any of our ponds or other ponds we've visited. He has more of an aversion to water than most cats.
This particular pond was completely covered with duckweed. I'm guessing the dog thought the bright green surface was just an extension of the lawn surrounding the pond. He went running head first into the pond, emerging microseconds later covered completely with duckweed.
That got me to thinking that I better give him a very thorough scrubbing on the other side of the watershed from my pond when I got home -- and which I did. I don't want any duckweed in my pond. I also sprayed off my boots and ran them through some potassium permanganate solution.
We've got several friends with water dogs and ponds. It also got me to thinking that I'm probably not going to let friend's dogs swim in my ponds anymore.
Just my paranoia getting the best of me ... But,
Regards, Ken

I don't think that is paranoi at all!!! Whatever we want to prevent from coning into our ponds may end up in there any way..but why help it along. I did a very bad thing this spring when I transferred minnows from one of my woodland ponds. I got lazy one morning and didn't exchange the water and wash off the minnows. Now after seeing DW along the shores I'm pretty sure I contaminated my 1 acre fish pond with DW. Dumb,dumb,dumb. Inventing and Engineering disposable medical products is a lot easier than this pond managment stuff! .

DW just plain shows up. One duck with some on its feet, its in. Ont snapper with it on its shell, its in. I got some in my new pond which my overjoyed fancy goldfish promptly ate. DW I don't think is a problem until your nutrient level can support it.
Example: 7yo pond garden, 6x12 feet or so, has always had a touch of DW but it has never covered the surface. Partly the two goldfish, but mostly the lilies and other plants rob the nutrients before the DW gets going. I have no idea how the DW got in my tiny pond in the first place, other than the occasional rather annoying herons.
