Glitched pet quest?

okay, so when i was getting the quest specialist medal, i was trying to squeeze some quests in and i did the trainer's command quest but i forfeited the quest after i got the letter. now, it's stuck in my 'in progress' and bartos won't have anything to say about the pet snack quest. because now i want the multiple pet effect but bartos won't say anything. i already bought the pet snack and stuff too. :l is there a fix to this?

i don't know what category this is supposed to go in so i'm sorry. D:
