It only "sounds" like a lot of work.
It was an hour a day for 42 days, then the second course was 35 days.
It went by fast.
As far as dog food goes, I learned 2 things about reading the lable.
Without getting too graphic, you know what happens to corn when you eat it, so don't give it to the dog. Read the lable. Dogs are carnivorous. They need meat. Again, read the lable. If it says by-products, don't give it to the dog.
