Sometimes dogs can suddenly exhibit bad behaviors. They just do whatever works. For example, if you see your dog barking at somebody or chewing something give them a treat to distract them. You will teach them that all they have to do is they would have to do such things to get a reward.
So, to solve those behaviors. Here are some of the tips to avoid those situations.
Keep them entertained.
When a dog has nothing else to do, he might try chewing or digging. You can be held somewhat responsible for this, as you should be providing your dog with daily exercise and entertainment.
Try to correct their behavior.
When your dog begins to exhibit a problem behavior, try to work on correcting it right away. The longer you let it go, harder it becomes. Some problem behaviors get to the point where they are almost impossible for the normal owners to handle. If you have these impossible tasks we are always happy to help.
