I took Cody to a Behaviorist when he was about 6 months and totally out of control. She was one of the Univ of Penna Vet Hospital best known and regaled doctors. Cody hated her, loved the assistant. She said Cody was dangerous, vicious, and that we would never be able to step over him if he's laying down, put our hand in his food, stare him in the eye...I paid over $200 for 2 hours and was so devastaed that I collapsed on the floor in tears. I loved that dog so much and the thought of not having him because of the nasty stuff was unbearable. Turned out, I found a great trainer who besides holding classes, came to the house..$35 and hour and the best money and time spent. Not only did Cody love her but she trained ME. Of course, he's not perfect but I can do everything and anything to him. He's a wiseguy sometimes but of course we all think it's hilarious. I was so disappointed in the psycologist, waste of money and everytime I see her on TV I razz her. She was more interested in eating her yogurt and staring at him then advising me. Don't waste your money. I'm not saying there aren't fabulous behavorists around, I just never reconsidered and looked for another. My attitude was more like "Oh Yeah? I show you!"
