Many of our dogs live in a world where all of their natural, primary needs are not met. Barking, chasing, digging, etc are usually repressed or followed with being told not to which can lead to dogs finding other ways to find outlets for behaviours that are natural to them. Here are some ways to provide outlets appropriately to some natural canine instincts.
Scavenging: dogs are natural scavengers and hold instincts in seeking and finding. Counter surfing and pulling apart the rubbish bins are both natural dog behaviours, albeit annoying ones. Allowing your dog to engage in natural scavenging behaviours by hiding treats or toys scattered in the garden or rolled up in a towel for them to find deters them developing undesirable habits. Get into the habit of providing positive outlets to scavenge and seek rewards in their daily routine.
