Suits these stages
Is the PETLIBRO Granary 5L Wi-Fi Automatic Feeder right for your dog?
- Who it’s for
- An adult dog whose mealtimes fall while you are at work, or a senior on smaller, more frequent meals that a person cannot always be home to serve.
- Who should skip it
- Your dog's kibble is larger than 15 mm (the listing's stated limit), your Wi-Fi is unreliable, or the puppy is young enough that every meal is also a potty-timing cue you want to see.
Editor's note. Ranked second on this shelf deliberately: it is the most-bought feeding product across our sister catalog this year and the only pick here that solves a schedule problem rather than a speed or a posture problem. It does not lead because a slow feeder is what most people searching this shelf actually need, and because the owner rating, while large, trails the bowls above and below it — the Wi-Fi and jamming complaints are real. Read them before you buy.
The verdict
An automatic feeder solves a clock problem, not an appetite problem, and that is the test for whether it belongs in your house. The Granary is the plain Wi-Fi model in PETLIBRO's line — Amazon flags a newer version with a camera and a food scale — and its listing is specific about the mechanics: a 5-litre hopper, portions of a twelfth of a cup, one to 48 portions a meal, up to ten meals a day, 2.4 and 5 GHz Wi-Fi, a ten-second recorded meal call, a desiccant bag the maker says to change every two weeks, and an infrared sensor that stops dispensing when the outlet is blocked. The number that decides fit is kibble size: the listing specifies dry kibble 2 to 15 millimetres across, and jams on larger kibble are a recurring owner complaint, so measure a piece before you buy. Pick it for an adult fed on a fixed schedule while you are at work, or a senior your vet wants on several small meals. Pick a slow-feeder bowl on this shelf instead if the problem is how fast your dog eats, and skip automation for a young puppy whose mealtimes are also potty-training cues. It cannot notice a dog who has stopped eating, which in an old dog is the first thing you want to know.
Drawbacks
- Kibble must be 2–15 mm across, per the listing; owners report jams on larger pieces
- Owners repeatedly report Wi-Fi disconnects and app frustration
- Cannot tell you a dog has stopped eating — a change in appetite still needs a person

If this one isn’t right
Skip it if: Your dog's kibble is larger than 15 mm (the listing's stated limit), your Wi-Fi is unreliable, or the puppy is young enough that every meal is also a potty-timing cue you want to see.
