I have a six month old Chihuahua and decided to switch dry dog foods. I was using Pedigree pal with no issues but was sold on the benefit when I saw it was for small dogs. After eating the Beneful her eyes swelled right up and her mouth. I did not realize that it was the food. I gave her Benadryl and took the food away in case. It was after a week when she got better. I tried the Beneful again and she instantly reacted! I don't know what is in this dog food but it's not good!
