I have had this 30lb 6month old Aussie for 2 weeks. I have tried her on Wellness puppy and Cali. Natural Puppy. The bag reads I should feed her 2-3 cups a day. She eats much less. If she eats a cup a day, I would be surprised. I have tried feeding 2x a day or leaving it out all day. Time of day does not seem to matter. She is active and seems to feel fine. She was checked out by the vet and all is well there so I don't think there is a health issue. Could it be that she just does not like either of these foods?
