Hi, does anyone know of a proven dog trainer/dog psychologist that can really help with my young gsd? He is from proven schutzhund lines and I plan to do agility with him, but i am struggling with his stress and over anxiety. I've had shepherds for nearly 25 years, but he is my first from working lines. I got him at 14 weeks and he was pretty much crated until then, but he's really hard work and in need help!
