I don't often try out new treats on them.. mainly because we've already tried the good ones at the local store, and all the ones we haven't tried have yucky ingredients. I just found a PetsMart in a nearby city though so I'll be picking up loads next week for Kai's birthday presents. =D

Kai's favorites are Marrowbones and freeze dried liver (Kaedyn doesn't have a favorite.. he loves them all!) Marrowbones have yucky ingredients but I still use them because he goes NUTS for them! I mainly use them for recall training.. since I want him to have great experiences with the "come" command. I also use little bits of cheese and rollover to agility training. The cheese makes him give that extra effort (the difference in speed is incredible!) but I mix it with rollover because it's cheap, less fattening, and he never knows when he gets good ol' rollover, or the jackpot =P

My/their least favorites are all the ones with yucky ingredients.. Eukanuba, Purina, etc. They just seem to know somehow!
