I can be a picky eater...I generally eat the same thing wherever I go...Taco Bell = 2 bean burritos with sour cream and mild sauce...Arby's = chicken salad wrap...and so on..I do venture on occasion...But, my dog is a picky eater too...I love my pets, but they do not buy the food. Here is Holden's bowl when I first feed him:

This is his bowl after he has sorted out the flavors he likes. He even likes to leave a few kibbles of the kind he doesn't like next to the bowl. I just pour the left overs back into the container, hoping eventually he'll eat it...
He's going to be real disappointed when all that is left is the kind he doesn't like. I did buy a different kind for him for the next go 'round...Hopefully he'll like it all...
