How long should a food transition take?

A gradual transition over roughly 7 to 10 days is a common structure to reduce sudden digestive changes.

What if my dog has loose stool during transition?

Slow the transition pace and keep one variable stable instead of making multiple diet changes at once.

Should I change treats during the same week?

No, keep treats stable during transition so results are easier to interpret.
