No, they eat wood. Also a dog won't work because beavers are only out a night and they really don't like getting out of the water. Fuckers. The area they have flooded is now over grown with reeds, which they eat. They have dug canals threw all the reeds about a foot deep and all that water is now spreading. Over the last two years, the wetland has doubled. Today I put in two more beaver pipes and we will see what happens. I just want the fucking water level down so my land doesnt turn into a lake.
