Agility is my favourite dog sport for a long time. First I was a little bit worried because Astor is a GSD (well mix) and I didn't saw any GSDs which enjoyed it, they all was soo slow and bored... But yes, Astor was from the start VERY different from the other GSDs, with more drive and energy... So I try... and Astor didn't dissapointed me... He've loved it. We've start doing it when he was 6 month old. He still loves it like I do. Destiny hah? :)) He is very fast and crazy on it, and specialy he loves tunnels. We're going to compete soon. Can't wait!
