Oddly enough it has been proven time and time again that unless there is a medical or genetic flaw in your dog behavior problems are a result of:
- Lack of training and discipline
- Lack of exercise and mental stimulation
Try taking your dog for longer walks (during the hot months use caution and take a lot of water) more often. Instead of 5 10 minute walks, try two 45-60 minute walks per day. This alone can curb and has been shown to stop behavior problems in their tracks.
