This is an excellent article and supports my initiative of suggesting that too much ball chasing can cause Obsessive Compulsive Disorders (OCD) and that simple scent-work games and ‘finding games’ are far better for dogs to live calm and contented lives and enable them to be more dog-like and express natural Canine Behaviours. If you would like advice on calming your dog and reducing their over excitement, please contact me.
