Good to know
- Every few weeks, feel your dog’s ribs and look for a waist from above, then adjust portions in small steps.
- Switch foods gradually over 7 to 10 days, mixing a little more of the new food into the old each day.
- Weigh daily portions on kitchen scales. A scoop or measuring cup can be well off, and small errors add up over months.
Common questions
How long does an opened bag of dry dog food last?
Once opened, kibble slowly loses freshness as the fats react with air. Keep the bag rolled tightly in an airtight container, away from heat and damp, and follow any guidance on the pack. If the food smells stale or rancid, or your dog suddenly loses interest, replace it.
Is grain-free dry food better for my dog?
Not automatically. Most dogs digest cooked grains well, and food allergies are more often linked to animal proteins than to grain. Grain-free recipes can suit some dogs, but if you are choosing one without a medical reason, discuss it with your vet.
