Dig Dogs, Dig - The Adventures of Red and Barkley
Ground Squirrels. They are a different creature than our tree-hugging squirrels in Houston. They tunnel underground. Barkley, being the terrier that he is, cannot allow these vermin to be in HIS yard. He has trained Red ( Red previously ignored squirrels and rarely dug...unless he needed to hide a toy ) to identify where the squirrels are, and then they dig, dig, dig to excavate these elaborate tunnels. And, since we have no grass, it's not too much of an issue....unless they get too close to the fence. To be fair to the puppies, they really haven't displaced too much dirt, just exposed the underground hollows that were already there. But, this has made our yard a tripping hazard. I've already filled in about 240 lbs of dirt. Thankfully, the squirrels seemed to have moved on. They torture Barkley and build new tunnels just outside the fence. But at least we don't have a terrier that is jumping fences ...
