Dog Food Log: How to Track Every Meal, Portion, and Restock Without the Guesswork

A free dog food log to track meals, portions, and stock — so you always know what's fed, how much, and when to buy more. See how PetMemo helps.

"Did the dog-sitter actually feed him dinner, or just top up the bowl?" A dog food log is the boring-sounding habit that answers that question — a written record of what your dog ate, how much, and when, instead of a guess pieced together from an empty bowl and a hopeful look.

It sounds like overkill for a dog that just eats the same kibble twice a day. It stops sounding like overkill the moment there's a second dog in the house, a vet asking whether a diet change actually helped, or a new sitter who needs to know exactly how much to scoop.

Why bother logging something as routine as dog food

Feeding a dog feels too repetitive to need tracking — until one of these shows up:

• Multiple dogs, multiple bowls, one memory. In a two- or three-dog household it's easy to lose track of who's already eaten, especially if one dog is on a prescription diet and the others aren't. A log settles "did I already feed her" without anyone having to remember.
• Weight and health changes need a paper trail. A vet asking "has he been eating less lately?" is a lot easier to answer with two weeks of logged meals than with a shrug. Gradual changes in appetite are exactly the kind of thing that's invisible day-to-day and obvious in a log.
• Treats and table scraps add up quietly. The base meals are easy to remember. It's the training treats, the dental chews, and the bite of someone's sandwich that quietly change how much a dog is actually eating in a day — and that only shows up if it's written down somewhere.
• Diet changes need a before-and-after. Switching food for allergies, a sensitive stomach, or a vet-recommended prescription diet only makes sense to evaluate if you know when the switch happened and what changed afterward — loose stool, more energy, less itching.
• Other people feed the dog too. A sitter, a partner, a dog walker, a kid who "already fed him" — anyone who isn't you needs the same information you're carrying in your head: what, how much, and whether it's already been done today.

None of this requires a spreadsheet or a diet app with calorie math. It just requires somewhere to jot down what got fed, to which dog, and when — a dog food log, in the plainest sense.

What a good dog food log should actually track

A sticky note on the fridge is technically a dog food log. It just falls apart fast. Here's what holds up:

1. A per-dog record, not a per-household guess

If there's more than one dog, "the dogs were fed" isn't specific enough. Each dog needs their own entry so a shared prescription diet, a picky eater, and a dog on a strict portion don't get blended into one vague note.

2. What's actually in stock, not just what's fed

Knowing a dog eats a particular kibble is only half the picture. The other half is whether that bag is nearly empty — a food log that's tied to a running inventory means "we're out" isn't a surprise you discover at 6pm on a Sunday.

3. Portions in your own words, not a forced number

Real feeding is rarely an exact 220g scooped to the gram — it's "a cup and a half, a bit less if he's had training treats that day." A log that only accepts precise numbers gets abandoned. One that accepts a free-text portion note gets used.

4. Preference, so you know what's worth rebuying

Six months from now, "did he actually like that food, or did we just finish the bag out of stubbornness" is a genuinely useful thing to have on record before you order another case of it.

5. A timestamped history you can look back over

The value of a dog food log isn't really today's entry — it's being able to filter the last two weeks and actually see the pattern: meals skipped, a food switched, a portion quietly shrinking or growing.

6. The real cost, not an estimate

Food is a recurring cost that's easy to lose track of across brands, bag sizes, and the odd emergency vet-diet purchase. A log connected to what you actually spent gives an honest month-to-month number instead of a guess.

Where PetMemo fits in

PetMemo is a free web app with a dog food log built in as part of its Nutrition feature — not a separate diet planner, but exactly the kind of practical log described above:

• Each dog gets their own feeding log and food links, so a two-dog household with different diets never gets mixed up between the two.
• Food is a shared household item with real stock levels — set a low-stock threshold once, and PetMemo flags it before the bag actually runs out.
• Portion size is a free-text note per dog, next to a simple loves-it / neutral / won't-touch-it rating, instead of a gram count nobody sticks to.
• A History view filters logged feedings by day, week, or month, so you can look back over how a diet change actually went.
• A "Log expense" shortcut turns a bag of food into a real, dated expense, so your Nutrition overview shows actual month-to-date food spend, not an estimate.
• If a dog is also on medication alongside a diet — common with allergies or a prescription food — PetMemo's medication tracker sits right next to the food log, on the same dog's profile.

It doesn't require a subscription to start, and it isn't built as a calorie calculator — it's a straightforward record you and anyone else feeding the dog can rely on, whether that's one dog on one kibble or three dogs on three different diets.

Frequently asked questions

Is there a free dog food log app?

Yes. PetMemo's Nutrition feature is free and lets you log food, portions, stock, and feeding history for every dog on your account, without a paid plan.

How do I log food for more than one dog without mixing them up?

Each dog gets their own profile and feeding log in PetMemo. A shared bag of food can be linked to more than one dog at once, but each dog keeps their own portion notes, preference, and feeding history.

Do I have to log every single meal for it to be useful?

No. The feeding log is optional and works best used when it matters — a smaller portion because a dog seemed off, or a new food tried for the first time — rather than as a mandatory entry for every bowl.

Can I track exact portions in grams instead of a free-text note?

You can write a portion note however you actually feed — "one and a half cups" works just as well as "220g" — since a free-text field fits how most people measure food day to day.

Does the log tell me when to buy more food?

Yes. Each food item has a stock level and a low-stock threshold you set, and PetMemo flags it once you're running low or completely out, both on the item and in a household-wide restock list.

Can I see how much I actually spend on dog food?

Yes. Logging a food purchase as an expense feeds into your Nutrition overview, which shows real month-to-date food spend pulled from those logged expenses rather than an estimate.
