Dog Poop Septic Tank

[MeredithMan]

Has anyone ever used one of those dog poop septic tanks? It seems that you can either buy one on-line, or go the DIY route, using an old trash can or 5 gal bucket. We have a fairly small yard at the lake and with 3 large goldens....well, you get the picture....

In trying to find a better solution, I recently learned of these dog poop septic systems, and was wondering if they really work.

Thanks!
