I can see a dachshund tunnelling, they're hunting joneses, but usually other breeds it's the female who wants to tunnel. We had a longhair female dachy who burrowed a lot. any of them would tunnel in snow when hunting mice.
I believe it. You should see the holes @ the dog park. Small dogs can go swimming they hold water like a well. Big dogs just drink out of them. Or put their front legs in them to cool off.
