Dog Mound

So I have a problem at my place, and it’s called a gopher. It’s digging around my place making all these dirt piles, and my dogs want to eat it. They find the holes, sniff around, dig, and wait for it to pop up. Thing is they have big teeth and can hurt your pets. So far not got nothing but one of them decided to lay on this mound it made. Pretty sure my cats would do a better job catch it anyways.
