Wow, $1200 between Zoey, Psyche, Crash, Simi so far, and all of the public classes Bella took. Adding to that another probably 2 grades of obedience for Simi, plus her agility classes (3 or 4 levels!), so yeah... lots of money.
And that's not including the money spent on trials that I used as training for Psyche, plus all the fun matches.
