FAQ

How long does it take to see results?
Most dogs show measurable weight loss within 4–8 weeks when portions are measured and daily exercise is added.

Can I mix weight-management food with regular kibble?
Gradual transition over 7 days is recommended; sudden mixing can reduce the calorie-control benefit.

Do I still need to measure treats?
Yes. Treats should not exceed 10% of daily calories; use low-calorie options such as carrot sticks or commercial weight-control treats.

Bottom Line
