I have researched the topic of moles and gophers but all of the answers seem to indicate mounds of different structures. These are tunnels that are very visible from the surface and start and stop all over the yard. I don't see any entrance holes but I have a black labrador and I have seem him digging at these tunnels. This is what prompted me go outside and take a look. He is very persistent with the digging but also known to dig because of his breed. I can not determine if these are in fact moles or gophers. We have lived here for 12 years and I have never seen either one. Do rabbits have tunnels to their nests'? There are quite a few wild rabbits in the area that have come under the fence and have dug holes to set up a nesting place.
