Why Gradual Transitions Matter

Abruptly switching a pet’s food can cause digestive upset — a gradual transition, mixing increasing proportions of the new food with the old over a week or more, generally reduces this risk.

A Typical Transition Timeline

A common approach gradually increases the new food’s proportion over roughly seven to ten days, though sensitive individual pets may need an even slower transition.

Signs a Transition May Need Adjustment

Digestive upset (vomiting, diarrhea, appetite changes) during a transition suggests slowing the pace further — an advisor should be able to explain this troubleshooting step to a concerned customer.

When a Poor Transition Response Needs Veterinary Attention

Persistent or severe digestive symptoms during a diet transition warrant veterinary evaluation rather than simply pushing through or repeatedly switching foods.
