If your dog is slowly turning your garden into a cratered moonscape then try not to despair, because dogs that dig are only doing what comes naturally.
Dogs dig for lots of reasons. The first step you should take, is to try to identify the reason why he is digging.
Your dog may dig because he has a genetic predisposition to be a digger. Terrier breeds can be notorious diggers, for example. Digging may also be part of a nesting instinct, particularly if your dog is pregnant or if your dog suffers from the heat. Digging exposes cool earth and provides a small shaded, shelter to lie in. Dogs may also dig to bury bones or toys because of a residual instinct to hide food from other predators. If your dog is digging under a fence or next to a gate he may simply be trying to get out of the garden. And, if it's none of the above then your dog may simply dig because he is bored and can't think of anything else to do.
What can you do?
Once you’ve identified why your dog is digging it becomes simpler to correct. All you will need is a little patience.
If your dog is digging in order to get out of the garden or out of plain boredom there are a number of options you can consider: Try to get rid of pent up energy by increasing the level of exercise. Take longer or more frequent walks and schedule some daily ‘playtime’ involving games like fetch that will tire out your dog.
It's a good idea to invest in some boredom buster interactive toys, for example a treat cube. You can fill these kinds of toys with kibbles which drop out as the cube toy is pushed and rolled around. Also keep a stock of interesting chew toys that you only give your dog when you leave. If you remove the toys when you return it will keep the novelty value high and these can be very effective ways to occupy your dog’s time.
For dogs who are digging just to keep cool on a hot day, the remedy is easy. Provide lots of cold water and a well shaded area that’s comfortable and close to where your pet enjoys lying during the day. The more comfortable your dog is, the more likely he’ll choose to nap instead of dig.
Digging is a perfectly natural dog behaviour and so if your dog still digs after trying a few of the above suggestions, create a “legal” digging spot. A child’s sandpit is perfect for this. Bury a few toys, bones or balls to help him get the idea. And when you see him digging where he's not supposed to, just stop him and take him over to his sandpit and encourage him to dig by moving some of the dirt around. It won't take your dog long to get the idea.
Never punish your dog for digging a hole unless you catch him in the act. Even if you bring your dog to the dig site he won’t be able to associate his digging with the punishment.
