Is Your Dog Digging?
What - If your dog is digging small holes, it's not a huge problem. If he's digging a crater in your yard, something must be done.
Why - Dogs dig for many reasons. Some dig when they're bored, some dig to bury things, some dig to create a sort of den for themselves, some dig to try to get out and some dig to follow a smell.
Where - Does your dog only dig near the fence? Then he is likely trying to escape? Near the trashcan? Then he's following a scent.
When - If your dog is digging when the sun is high, he's likely trying to cool off.
The Solution: Determine what is going on in your dog's environment outside. If he's reacting to noise or heat or the neighbor's cat slinking into the yard, bring him inside. To cure those who bury things, do not leave any toys or bones out with your dog.
To keep a dog from digging to get out, place patio stones along the fence. And to thwart a scenthound, cover areas in cedar to distract his nose.
