Yes, small donations actually work — the math

A specific belief keeps a lot of would-be donors on the sidelines: the idea that unless you can give a lot, giving a little is not worth the effort. The belief is intuitive and it is wrong, and the reason it is wrong is worth spelling out in full.

The unit cost is genuinely small

An average adult shelter dog eats between 250 and 400 grams of dry kibble per day, depending on size and activity level. At the wholesale prices most mid-sized shelters pay, that is between US$0.14 and US$0.24 per dog per day. A single dollar reliably buys a full day of food for at least four dogs. Two dollars a month, given consistently, is meaningfully more than a single ten dollar gift given once a year, both in total value and in operational usefulness.

Predictability is worth more than size

Shelters plan their food orders on a monthly cycle. A pool of donors reliably contributing small amounts every month lets a shelter commit to a larger wholesale order, which unlocks a lower per-pound price, which stretches every dollar further. Large one-off gifts are welcome but harder to plan around — they either sit unspent in a reserve or trigger an ad-hoc order at retail-ish pricing. This is not a hypothetical: several of our partner shelters told us that a US$500 predictable monthly floor changed their purchasing conversations with suppliers more than a US$3,000 one-off cheque had six months earlier.

The math at 10,000 players

FeedPups is a small operation. Let us imagine, conservatively, ten thousand people using the site in a given month. If a third of them see one ad each with a US$0.002 net revenue after Google’s cut, that is roughly US$6.60. If 1% of them buy a small credit pack at US$3, that is another US$300. Together, minus fees, we can invoice about US$260 of kibble that month — roughly 1,400 dog-days of food. None of the individual contributions were large. All of them, aggregated, funded a genuine operational contribution to a partner shelter.

Where the effect breaks down

Small donations work when the collection and distribution overhead per donor is close to zero. This is the entire reason FeedPups exists as a game rather than a mailing list — a shelter processing five thousand two-dollar cheques individually would spend more on stamps than it received. Pooling small donations only makes sense if the pooling mechanism is cheap. Any donation platform where the processing fee eats more than 10% of a small gift is a bad venue for that gift; look for one that either subsidises fees or aggregates before distributing.

What "consistent" actually means

You do not need to set up an automatic monthly payment for consistency to work. What matters at the aggregate is that some percentage of the audience is present each month. If you play FeedPups occasionally and see an ad, you are part of that percentage without having to think about it. If you buy a credit pack every few months when you happen to remember, you are contributing to the pooled predictability. The shelter never sees your individual pattern; it sees the monthly aggregate, which is stable enough to plan around.

The honest ask

Do whatever you can. Playing costs nothing and quietly helps. Buying a small credit pack helps more per dollar. Following your local shelter’s wishlist and picking up one item on your next grocery run helps them directly. Sharing this site with one friend who likes dogs materially expands the audience the ad revenue is based on. All of these are small actions. The reason they matter is not sentimental — it is arithmetic.
