Does your dog like to dig or tear things up? These behaviors can be frustrating and very hard to stop. There is a simple solution, tho, that reduces the frustration for the dog and the human.
Destruction Use enrichments that allow the dog to tear something up. Toss a couple of treats into a cardboard box, a paper towel insert or a paper bag that you then roll up. Yes they will make a mess but iti's an easy one to clean up and may save your furniture.
Digging set up a digging area where it is allowed. Motivate the dog to use this area by partially burying some favorite toys and then redirect this area. They will learn to dig there rather than in your garden, along the fence or other areas.
Remember, the more mental stimulation they get the less you will see these types of unwanted behaviors.
