Montego Classic Dog food moldy!!!

If I could rate 0 i would. I am not happy about the dog food. every month for 5 years I have bought montego. Since mid March this year i have been noticing that the pellets have been getting substantially smaller. also last month I purchased a bag of Montego Classic (with new packaging) and the food seemed to be fine up until I used half the bag i started finding mold on the pellets and discontinued using all Montego products entirely due to my dogs getting ill. This is unacceptable and I'm not happy at all.
