	We have had our dog on Royal Canin for about a month now. He goes to doggy day care on the weekends. This past weekend he has had some issues with snapping at his doggy friends. He has never shown any ounce of any kind of aggression before. A girl at Spencer's day care said that sometimes the ingredients in the dog food can cause these types of changes. Is there anyone out there that feeds there dog this brand before and had this happen??
