i have a 6 month old staffy pup that is constantly digging holes under our fence to get to the dogs next door. we've tried everything we can think of to stop him. we've put his pooh in the holes, we've yelled and hit him and rubbed his nose in it then tied him up. i no its a boredom thing as he only does it when DP and i are at work. its come to the point where he has to be tied up everytime we leave the house and i hate having to do that to him. we walk him all the time down the local dog beach so he interacts with loads of humans and dogs as he is so social. i just cant think of anything else that we can do! please help. its driving me crazy. specially seen as the dog next door comes through the holes into our yard and barks and nips at us.
