My name is Marcelo and I'm from Argentina. I have a female German shepherd and tomorrow comes a puppy border collie (female too). I practice Agility with her and I teach my dog basic things using clicker (and I use it to improve performance in Agility too), but I want to add more tricks, and I hope that your methods help me to do that. Thanks in advance, sorry about my English, but is not my first language. Bye..
