Can any dog food get bugs, or just grain-inclusive formulas?

Updated On September 23rd, 2025

Pet's info: Dog | Cavalier King Charles Spaniel | Female | spayed | 5 years and 11 months old | 17 lbs

Is it more likely for dog food with grains in it to be infested with bugs or can this happen to any dog food? Please explain. I'm thinking of switching my dogs food so something with grains and I'm wondering if this will store well.

Hello. Any food can become contaminated with bugs if it is not stored properly, or sits too long in a warehouse. Do not buy any damaged or repaired bags & avoid bags that are marked down in price. You can also avoid any problems at home by keeping an open bag of food in a tightly sealed container & only buying a months worth of food at a time. Thanks for using Petco Pet Education Center, formerly Petcoach.
