he is too big to agility and although he is really well trained I don't enter shows with him as he is very difficult around other dogs. Why I don't know as I know nothing nasty happened to him when he was young and he was properly socialised. I did have a "reading" done on him some years ago and one of the things that came up about this attitude was that he wanted me all to himself and didn't want other dogs around me. WHo knows. i do many tricks with him, for which he has certificates, he can play dead, roll over, twist one way, turn the other way, high five, "touch" get into a box, he can read, and count, fetch my keys and play dead. He lOVES his tricks and has 32 Certified tricks to his name. He is nearly 10 yrs old but still as strong as a horse. I love him - I just wish he would let me have a cat
