I am feeding my 2 dogs Purina Dog Chow currently and I am looking to switch their food. My puggle has been throwing up lately, my lab is over weight (she gets 3 cups of food a day) and I also want to decrease the amount of stool they produce and also get them the nutrients they need. Does anyone know of a food the is natural and high quality but reasonably priced? Any advice and suggestions will be greatly appreciated!
