The "Indoor Exercise for Your Dog" article is full of misinformation. LASER LIGHT - Dog Behaviorists, Vets and Trainers along with rescues and humane shelters have stated that using LASER LIGHTS as a toy for dogs is NOT RECOMMENDED. This has been known to cause serious mental health issues with dogs as they will fixate and obsess. This type of toy game is best suited for FELINES NOT CANINES. TUG OF WAR - I went through the training material upon joining TRAINPETDOG.COM and here is what was stated about tug of war. [b]Discourage: Tugging Games[/b] Although tug of war can seem like a very fun game, it can also teach some really bad habits. For one, it will teach the dog that he is on the same level as you or even higher, especially if he wins the toy during the game. In addition, tug of war can lead to jumping up and biting on clothes and hands, which is a habit you want to avoid. IN the future it's best to be knowledgeable or at least do some research when posting an article. I am highly discouraged by reading this article about this website, the information posted here and trainpetdog.com[size=4][/size][color=#FF0000][/color]
