How to weigh pet food: zero the bowl, then measure the meal
Put the empty bowl on a suitable kitchen scale, select grams and press tare or zero before adding food. Measure the amount in your pet's feeding plan. A scale measures the portion; it does not decide how much your dog or cat needs.
Make the amount clear before touching the scoop
Check that your note names the exact food, the pet and whether the amount is per meal or per day. AAHA recommends weighing food with a gram scale rather than relying on cups. Tufts explains why a cup measures volume, not a fixed weight: different foods and different scoops do not give one universal grams-per-cup value.
Zero the bowl, not the food
Place the scale on a firm, level surface and select g. Put the empty bowl on it, press tare or zero and wait for 0. Add food until the display reaches the planned amount. The bowl's weight is now excluded. If you add too much, remove some food rather than zeroing the full bowl and losing the measurement. Use a scale intended to measure that portion; check its instructions for minimum load and accuracy.

Turn a daily total into a visible routine
Illustrative example: a plan says 80 g of one dry food per day, split between two meals. That is 40 g per meal, not 80 g each time. If the same plan reserves 10 g of that food for rewards, 70 g remains for the bowls: two meals of 35 g. These are arithmetic examples, not recommended portions for your pet. Do not apply the same subtraction to a different treat or food: its calories per gram may differ.
Keep the record useful when someone else feeds
Label each pet's daily portion and note food already given. Record food offered separately from leftovers or uncertain intake. When you change foods, check the new label and feeding plan; the same gram weight can supply different calories. If the plan only gives cups, ask the clinic or manufacturer for the amount in grams for that exact food. Your veterinary team can help set and review an individual target; the scale cannot assess body condition or medical needs.
FAQ
Do I weigh the bowl too?
Put it on first, then tare the scale. The display should read zero before you add food.
Does 100 ml of kibble weigh 100 g?
No. Millilitres measure volume and grams measure mass. There is no universal conversion for kibble.
Can I weigh wet food?
Yes. Tare a clean bowl and weigh the portion in the feeding plan. Follow the food's storage and handling instructions.
