When you think about it, many of the reasons causing the dog’s desire to dig suggest their own solutions: if your dog’s not getting enough exercise, take him for more and longer walks.
Generally, a minimum of forty-five minutes TWICE a day of walking at a good pace is needed for many active dogs, and some dogs need active play time on top of that amount. That will help control the dog digging problem.
If you feel the dog is bored, load him up with toys and stuff to chew on. Especially hollow chews stuffed with tasty food to keep him busy for hours on end.
If you exercise him enough, he’ll tire out and sleep a good part of the day.
If the dog is a confirmed escape artist and nothing else works, you may have to confine him to a crate or pen in the house during the day if no one is home to watch him.
That sounds drastic, and very few dogs are like that, but it may be the only way to control dog digging.
Dog digging for some dogs is simply fun and they do it just for the sake of digging. It’s like a hobby to them. All you can do is control where the dog goes and provide him with a place to do his thing.
Restrict the dog’s access to the yard. If the dog is not in the yard without active supervision, he won’t have a chance to dig.
A natural deterrent to digging is dog poop. Most dogs will back off from anyplace there’s poop. Spread bits of poop where you don’t want the digging.
Try to trick him
It’s time consuming, but effective. Roll up an inch or two of turf in the yard and lay down chicken wire underneath. The dog will try to dig and quickly find his effort is useless and quit, having decided digging in the yard is pointless.
Or, you can give in to your dog’s need to dig and give him a place to do it.
If you are determined to prevent dog digging under your fence or turning your yard into a grass-less crater-studded lunar landscape, consider this preventative strategy... if the dog is a true digger, it’s his personality and he needs the chance to express it so there is no need to keep kidding yourself.
Allocate an area to the dog where he CAN dig, and dig all he wants.
