Found the following article online, use it to answer the question: What causes Kosis to realize he needs counseling? The Goofy Gophers are about to harvest the vegetables on the farm when the farmhands beat them to the punch. Worried that their food source is being "vandalized," they follow the truck to the barn so they can recover what they consider to be their food. However, they spot the guard dog and realize that if he were to awaken and spot them stealing the vegetables, he would cause them trouble. The Gophers spend most of the rest of the cartoon using psychological weardown tactics to drive Barnyard Dawg insane and remove him as a threat to their well-being. A deadpan pig watches as the dog is repeatedly the victim of the Gophers' pranks, and can only shake his head as the dog's psyche is broken down. Meanwhile, the pooch tries to convince himself that all that is going on is nothing but a bad dream (consulting Sigmund Fraud and using sleeping pills to laugh off each attempt). In the end, the Gophers get rid of their foe for good by tying a harness around the sleeping Barnyard Dawg's belly, then attaching it to a hot air balloon before launching it (getting a tear in at as it goes up), leaving them free to "raise their vegetables" into a long pipe leading from the barn to their burrow. Meanwhile, the balloon's hull leaks out completely, and the dog awakens atop a light pole. After he wakes up and realising his surroundings, Barnyard Dawg mentally snaps and begins to fly! The pig - confused about everything he has seen - goes to psychiatrist Dr. Cy Kosis for counseling. Kosis realizes he needs counseling (and joins his client on the couch) when he sees the Barnyard Dawg flying by the window.
The answer to this question is:
he sees the Barnyard Dawg flying by the window
