There have been lots of threads on dog food. If you can afford it and are happy with it stick with it. I have feed lots of different foods Iams, science diet, eukunuba (sp?), Nutro. I have had great results with purina Pro Plan, shinny coat, great muscle tone and they are a big supporter of the dog games and they had NO problems with the Pet food Recalls. The last two bags (four monthes) I have fed Exceed from Sams Club and have had good results as well $28.00 a 40lb. bag. Ingredients are the same as Pro Plan and you get vouchers from purina with it so I,m guessing it is made by purina. Feed what works for you and what you can afford.
