Some dogs simply love to dig holes. The reasons they do that are different though. It depends on the breed of the dog and the situation of each of them. It is possible that a dog digs holes just because of deep boredom. If you suspect that is the cause, it means you must pay more attention to the dog, take it out more often am exercise the dog a lot. That will exhaust the dog, and the digging mood will go away.
If you own a male dog, it is possible it started digging in the purpose of reaching a female dog in heat that lives next door. In this case, neutering the dog will fix the problem. If your dog only digs to burry things or just for the sake of the digging itself, in this case all you can do is arrange a special place in the garden where the dog can do that without damaging the surroundings. Protect the rest of the garden by spraying it with a dog rejection non-toxic substance, inside and around the area where the dog must not dig.
Most dog owners encounter various behavior problems with their dogs. Most of these issues seem funny at first sight, but the owner must teach the dog good manners.
If the dog digs holes, try to catch its own tail, rolls in the garbage, etc, but occasionally, that is normal. However, if the dog does all those things on a regular basis, that means there are behavior issues which need solution.
Behavior issues might be genetic, for example the Bull Terrier is knows to be famous for circling themselves to catch the tail. At first that might seem funny, but if this habit persists, the dog will end up chasing the tail constantly, will only stop when it is too tired and will go back to doing it as soon as it gets some rest. Behavior problems may appear because of an action known by the dog from the owner, but the dog uses its own way to apply it, and the occasions will be a lot different from a human. For example if you teach your dog not to jump or to bark when guests enter your home, and for that you reward it, in time, the dog will have no reaction when you come home, and that is only to get his biscuit of his reward. This is an example of a simple deviant behavior, but most of the issues are a combination between causes.
What can you do in order to avoid deviant behavior?
First step is get your information about the different types of behavior dogs can develop.
Try to impose yourselves by being firm, but not by force nor by aggressiveness.
Find the source of the dog’s behavior, for example if the dog becomes aggressive when somebody takes away the favorite toy, buys more similar toys, and this way, in time, the dog won’t miss it anymore. In time, it will change its behavior.
The dog must learn to obey every person in the house, all family members, not just one.
The vet must know exactly what type of behavior the dog has, because he certainly knows more methods to remove a habit than you do, and the vet can recommend a trainer for difficult cases.
As you know, dogs and wolves behave pretty much the same, so just like inside a wolves pack, the dog must acknowledge that in its family, it is not in command and it must obey the master.
