We switched to Canidae ALS after the tainted food scare. We were very happy with our choice and I recommended this food to many people. Then they changed the formula. They made this major change without so much as a sticker slapped on the bag notifying their customers. The change sent my dog into a tail spin. Severe vomiting, diarrhea, hot spots and itching were the main symptoms. And since she had always done so well in Canidae, I never dreamed it was the food. After weeks of worry and meds and messes to clean plus prednisone for the scary hot spot (my vet shrieked when she saw it!) I started researching and a food change was the only thing that stopped the problems. She lost 5 lbs. in a very short amount of time. Canidae's customer service rep. blamed me for not transitioning properly! Talk about adding insult to injury! Not a good food for us and not a good company to deal with. Wish I could give ZERO stars.
