This can come in all shapes and sizes. Barking, licking, jumping, whining, stealing objects, meowing, knocking things off your shelves/desktop, etc... Most are learned through inadvertent random reinforcement.Most are readily fixed, though the solution isn't as simple as you might think. Many would offer that you're not giving the dog enough attention and they need to be given more. This is often not the case. Many of these animals get lots of attention but can't quite seem to get enough or are always wanting more. There are certainly those cases where more activity is in order, but it needs to be provided in very specific ways to meet the needs of both the owner and the animals in the situation. Owners need not have to change their whole lives to accommodate the needs of the animal to resolve attention seeking disorders.
