Common triggers
The 25 ingredients most often behind food reactions in dogs and cats, and the 208 alternative names they hide under on ingredients panels.
Beef, dairy and chicken top this list largely because they're the most widely fed, not because they're uniquely allergenic. Animals become allergic to what they've been exposed to.
