Tractor Supply had this brand on sale a few weeks ago for cheap, $34 for a 35 lb bag of the mature adult formula and it looked good on the label so I bought it. After about 10 days on it Pasta started having serious diarrhea and loose stool which has not happened to her for years. She's not eating anything else out of the norm so I switched back to TOTW today and started giving her probiotic treats. Has anyone else had issues with this brand food or had any experience with it at all? My husband's dog is on the 4health grain free formula and seems to be doing fine.
