Beneful Original Dog Food Review

We previously fed our dog Beneful and she liked it for about five years, but then she quit eating it and we had to coax her to eat it or just let her not eat a few meals.  I asked the vet about what dog food was the best for he (she was 7 years old at the time) and he said to try a better brand.  He said that Beneful was full of fillers.  I am not sure, but just telling you what a veterinarian says about Beneful.  Of course, vets are always trying to sell you their high priced food too, right?
