My dogs ate more table scraps than dog food and loved fresh vegetables too! One memory that I will never forget, is watching my male and female Blue Heelers/Australian Cattle Dogs laying in my kitchen floor eating carrot peelings that hit the floor. I just handed them a bag of baby carrots--the male opened it with his teeth and gave the female one at a time as she finished eating one. Course he ate too, but it was so ADORABLE!
Otherwise, I just bought the Diamond Naturals. Usually bags would cost no more than $40 for a 50lb bag, only available at farmers stores, co-ops, and most pet stores. It had good nutrition and I am sure other brands could have been a better choice, but like I said, my Australian Shepheards and Heelers ate more table scraps than dog food.
