An automatic dog feeder keeps meals on time when work runs late, mornings start early, or you want portions measured the same way every day. The best automatic dog feeders do three things well: they dispense the amount you set, they warn you (or at least keep going) when something goes wrong, and they are easy to clean.
Which one is best depends on your dog and your routine. A 10-pound terrier and a 90-pound shepherd need very different portion sizes and hopper capacity, some owners want a phone app and a camera while others prefer a simple timer with no WiFi, and dogs on wet or raw food need a different design altogether. The picks below are grouped by the job each one does best.

Best overall smart feeder
1. PETLIBRO Granary Smart Feeder (WiFi)
The Granary is a 5-liter WiFi feeder you schedule from the PETLIBRO app. It dispenses in small portions of about 20 ml (roughly 1/12 cup), from 1 to 50 portions per meal, so it is easy to fine-tune meals for a small or medium dog. It works on both 2.4 GHz and 5 GHz home networks, and the app alerts you when food runs low or the outlet jams. If the power goes out, three D batteries keep the feeding schedule running, although WiFi and the buttons switch off until power returns. PETLIBRO lists it for dry kibble between 2 and 15 mm.
- Good: fine portion control, dual-band WiFi, low-food and jam alerts, and a battery backup that keeps meals on schedule
- Watch out: PETLIBRO says it is better suited to small and medium pets than large dogs; dry food only; backup batteries are not included
- Skip it if: you feed a large breed several cups per meal, or your dog eats wet food
Best with a camera
2. PETLIBRO Granary Smart Camera Feeder
This model pairs the same 5-liter hopper and 20 ml portions with a built-in 1080p camera. PETLIBRO lists a 145-degree lens, night vision, two-way audio, and motion and sound alerts, so you can check that a meal actually dropped and that your dog came to eat it. Saving video needs a microSD card (sold separately) or PETLIBRO’s paid cloud plan. On battery backup the camera and WiFi switch off, but scheduled meals still dispense.
- Good: see and talk to your dog at mealtime, plus the Granary’s alerts and portion control
- Watch out: costs more than the plain Granary; video history needs a microSD card or a subscription; same small-to-medium dog focus
- Skip it if: you already own a pet camera; our pet camera guide covers treat-tossing models
Best for large dogs
3. PetSafe Smart Feed (2nd Generation)
Big dogs need bigger meals, and the Smart Feed is built for that. PetSafe lists a 24-cup hopper, up to 12 meals a day, and portions from 1/8 cup up to 4 cups per meal, scheduled through the My PetSafe app or by voice with Alexa. A conveyor dispenser is designed to help prevent jams with dry and semi-moist food, and the lid, hopper, stainless bowl and bowl holder are top-rack dishwasher-safe. It runs on an AC adapter, with optional backup from four D batteries (not included).
- Good: large 24-cup hopper, up to 4 cups per meal, app and Alexa control, dishwasher-safe parts
- Watch out: connects to 2.4 GHz WiFi only; make sure the listing is the 2nd-generation model
- Skip it if: you want a camera or you only need a few small meals a week
Best without WiFi
4. PetSafe Healthy Pet Simply Feed
If you would rather not connect a feeder to your network, the Simply Feed is programmed on the unit itself. It shares the Smart Feed’s 24-cup capacity, 12 meals a day and 1/8-to-4-cup portions, and adds a slow-feed setting that spreads one meal over 15 minutes, which may help dogs that gulp. PetSafe says it handles dry or semi-moist kibble up to 3/4 inch across. It runs on four D batteries; a wall adapter is sold separately. The bowl, holder, lid and hopper go in the top rack of the dishwasher, but the conveyor is hand-wash only.
- Good: no app or WiFi to set up, large capacity, built-in slow-feed option
- Watch out: no phone alerts if something goes wrong; you need the separate adapter if you do not want to rely on batteries
Best budget pick
5. PetSafe 5 Meal Pet Feeder
The 5 Meal is the simplest design here: a rotating tray with five 1-cup compartments and a digital timer. The first compartment is available right away and the others open at the times you set, which works well for a day trip or a late evening. PetSafe lists it for dry or semi-moist food and for cats and small-to-medium dogs. It runs on four D batteries and the tray is top-rack dishwasher-safe.
- Good: simple to set up, no WiFi, and the tray is easy to wash
- Watch out: one cup per compartment and only five compartments per fill, so it suits short absences and smaller dogs
- Skip it if: you need several days of meals between refills
Best for wet or raw food
6. Cat Mate C500 5-Meal Automatic Feeder
Hopper feeders only handle kibble. The C500 uses five covered compartments on a rotating tray, with two ice packs underneath to keep food cool. The manufacturer lists each compartment at up to 330 g of wet food or 155 g of dry, and says it works with wet, dry or raw diets. Three AA batteries power the timer, and the lid and bowl are dishwasher-safe. It is made for cats and small dogs, so portions are small for anything larger.
- Good: takes wet, dry or raw food, ice packs included, long battery life
- Watch out: only for small dogs; ice packs keep food cool for a limited time, so ask your vet how long wet or raw food can safely sit
- Skip it if: your dog is medium or large, or you need more than a day of meals

Which automatic dog feeder fits your routine?
You work long or unpredictable hours
An app-controlled feeder such as the PETLIBRO Granary lets you shift mealtimes from your phone and tells you if the hopper runs low or the outlet jams.
You want to see your dog eat
The Granary Smart Camera Feeder confirms each meal on video and lets you call your dog over with two-way audio.
You have a large or giant breed
The PetSafe Smart Feed dispenses up to 4 cups per meal from a 24-cup hopper, so big dogs get full meals without daily refills.
You don’t want another app
The Simply Feed and 5 Meal are programmed on the unit. Nothing to pair, and nothing breaks if your WiFi goes down.
Your dog eats wet or raw food
Choose a tray feeder with cooling, like the Cat Mate C500, and keep wet food out only as long as your vet recommends.
You have two dogs
Most feeders here serve one bowl. PETLIBRO also makes a dual-bowl Granary with a splitter; dogs that steal each other’s food may still need separate feeders in separate rooms.
How to choose an automatic dog feeder
Match portion size and capacity to your dog
Check the largest portion per meal, not just the hopper size. Small-portion feeders such as the Granary are precise for small dogs, while large breeds need a feeder that can drop several cups per meal. Tufts University’s Petfoodology team notes that measuring by cups is often inaccurate, so weigh a few dispensed portions on a kitchen scale and adjust the settings.
Decide on WiFi or a simple timer
App feeders let you change schedules remotely and send alerts, but they depend on your network; check whether the model supports 5 GHz or only 2.4 GHz. Timer-only feeders are simpler and keep working if the internet goes down.
Look for a power backup
A feeder that stops when the power cuts out defeats the purpose. Most picks here can run on D or AA batteries; check whether the batteries are the main power source or only a backup, and whether they are included.
Check the food type and kibble size
Hopper feeders are for dry kibble and sometimes semi-moist food, and many list a kibble size range. Wet or raw food needs a covered tray, ideally with ice packs.
Make cleaning easy
Food oils build up in hoppers and chutes. Removable, dishwasher-safe bowls and hoppers make weekly cleaning far more likely to happen.
Plan meal frequency with your vet
VCA Animal Hospitals notes that most adult dogs do well on one or two meals a day, with package guidelines as a starting point. An automatic feeder makes a schedule consistent, but it does not replace checking your dog’s weight.
Frequently asked questions
Are automatic dog feeders good for dogs?
They can be. A feeder keeps meal times and portions consistent, which helps with weight control. Cornell’s Riney Canine Health Center calls obesity the biggest health problem in canine medicine, so measured meals are a plus. A feeder is not a substitute for someone checking on your dog, fresh water and exercise. This is not veterinary advice; ask your vet about your dog’s diet.
Can an automatic feeder handle wet food?
Hopper feeders cannot. Use a tray feeder with covered compartments and ice packs, such as the Cat Mate C500, and keep wet or raw food out only as long as your vet advises.
What happens if the power or WiFi goes out?
Most of the picks here keep dispensing on battery backup. On the PETLIBRO Granary models the app, buttons and camera switch off during a power cut, but scheduled meals continue. Timer-only feeders do not use WiFi at all.
How do I stop my dog breaking into the feeder?
Place the feeder against a wall or in a corner, choose a model with a locking lid where available, and supervise the first few days. Rotating-tray feeders are lighter, so they suit calmer dogs best.
How we chose
This guide is research-based: we did not test these feeders hands-on. We compared manufacturer specifications from PETLIBRO, PetSafe and Cat Mate, feeding guidance from veterinary sources (VCA, Tufts and Cornell), and recall searches on CPSC.gov, where we found no recall for these feeder models. We favored feeders sold on Amazon US with clear specs on portion size, power backup and cleaning, and grouped them by the routine each one suits best. Read our full editorial policy.
