<upswing vole year (They follow a cyclical population
pattern as do varying hares, lynx, lemmings, etc>
I have a golden retriever who digs and kills moles, voles, and, of all
things, shrews (I guess he knows they eat earthworms). One day I went out
and he had excavated the yard around one of my iris beds, but had stopped at
the edge of the bed. I suspect a herd of predatory cats would do less damage
to the yard, but a dog with religion (the Master said to stay out of the iris
beds) would eliminate the habitat for them. Predators give safe, long
acting, reliable but usually less than 100% control.
And yes, he definitely keeps the deer out of the flowers, but our deer
density isn't yet up to the level where they are hungry enough to eat
anything unless shot or chewed on by wolves.
