Charlie D. and I took our 2 adult Bs, our first Bs, to training classes in the 90s. The dogs reluctantly passed but it was suggested that we retake the classes. The stay was the hardest command! One B had a high prey drive and wanted to go after the small white fluffy dogs and the other one was so friendly and had a thing for larger dogs that he would sit in the ring and turn his head around to watch the large dogs in the other ring. Once the teacher had to come up and wave her hand in front of his face to distract him! I think he wanted to be a large dog. He later earned his CGC although was told he was too friendly and both became excellent lure coursers with titles. We never did retake the training classes. I do not think I could take the embarassment!
