i used to feed Poopy nutromax, switched to science diet, then switch to nurtro again (just a different flavor) but recently went on a mission to find quality, healthy food for Poopy so he can grow to be healthy. i went to this small boutique near my house and discovered three dog bakery which has this baked food that is 100% human grade quality and all natural. it's baked slowely to keep the taste for them... poopy loves it. i noticed when he was eating all the other brands, his poo poo seems bigger, softer, really nasty...but since i switched to three dog bakery, his poo poo is harder, less smelly, and smaller...you can tell that he's getting better quality food by looking at his poo poo.
it does cost more, but because there is so much good quality stuff, you only need to feed him like half of what you'd feed him with the other brands. so in the end it actually is costing me less to feed him... below i pasted the link to the bakery. if there is none in your area you can order online. one box of baked dry food will last a good 6 to 9 months depending on type of breed, but for yorkies, it seems that i havent even touched the bag at all... they also have baked treats that my husband thought was for him cuz they looked so yummy. they sell soft and hard food. you should check it out. we love it...
