I have an 1,5 years old American bulldog. She is trained, that is, she knows a few commands and even have passed a basic training exam named "City dog" (this exam is obligatory to every dog in Ukraine whose owner pretend to have trained dog). Besides, she's wonderful dog on her own. Leaving aside learned commands, she's quite well-behaived and very calm and good-tempered (I belive this is common for most American bulldogs). However, I still feel that we can do more together, learn some funny tricks etc. So today I bought a clicker and I'm going to introduce it to my dog as soon as possible. I hope, the materials on this site will be most helpful for learning the basics of clicker training)
