It's 6 p.m., you're stuck in traffic, and your dog has been staring at an empty bowl since 5:30. An automatic dog feeder fixes that, and it also stops the "I fed him" / "no, I fed him" fight at home. Here are the 5 best automatic dog feeders in 2026, ranked by star rating and review count, with a plain note on which ones are really cat feeders that also work for small and medium dogs.

We didn't personally test these. We read the listings and the reviews, compared the specs, and ranked them. Our 50 lb dog food container guide pairs well with the bigger models below.

What to Look For in an Automatic Dog Feeder

Capacity vs. dog size. A 4L feeder holds about 17 cups of kibble. That's fine for a small dog, but a lab can empty it in a few days. For large dogs, look at 8L to 12L models (34 to 50 cups).

Kibble size. Many feeders jam on large or oddly shaped kibble. Check the listing for a maximum kibble diameter. Anything over about 15mm needs a feeder built for large kibble.

Power backup. Look for a plug plus batteries (usually D cells). If the power flickers while you're at work, the schedule keeps running.

Wi-Fi, camera or no-frills. An app lets you change meals from your phone and some models show you your dog eating. The simple button-and-screen models cost less and have nothing to disconnect. Note that most app feeders only connect to 2.4GHz Wi-Fi or 5G on specific models, so check yours.

Dry food only. Almost every feeder here is made for dry kibble. Wet food spoils sitting out, so these aren't built for it.

The 5 Best Automatic Dog Feeders in 2026

1. VOLUAS 4L Timed Automatic Feeder

Best for: small to medium dogs and anyone who wants a cheap, simple feeder.

Check Price On Amazon

This is a no-app, button-and-screen feeder that holds 4L, or about 17 cups, of dry food. It runs on the plug or on batteries, so a power cut won't miss a meal. It's sold as a cat feeder "for cats and dogs," so think of it as a pick for dogs up to medium size.

What makes it stand out: A giant review count (over 12,500) at 4.4 stars, which is the best proof of reliability in this list. You get 1 to 4 meals a day, up to 40 portions per meal, a voice recorder and a stainless steel bowl.

Good to know: It's built for smaller kibble and smaller appetites. A big dog will go through 4L quickly, and there's no Wi-Fi, so you can't change anything while you're away.

2. Petory 4L Timed Automatic Feeder

Best for: a low-cost feeder for small dogs and multiple small pets.

Check Price On Amazon

This is a very similar feeder to the VOLUAS: a 4L tank (16.9 cups), a dual power option (plug and batteries), a timer and a stainless steel bowl. It can run six separate meals, which is useful for puppies or small dogs on a split schedule.

What makes it stand out: 4.4 stars across more than 5,500 reviews, with 6 meals a day, up to 50 portions and a sealed lid that helps keep food fresh. It's among the cheapest in the group.

Good to know: It has the same limits as the VOLUAS. It's marketed to cats first, and the kibble opening is small, so large-breed kibble can get stuck.

3. PETLIBRO Granary 5L WiFi Feeder

Best for: owners who want app control and a sealed hopper without paying for a camera.

Check Price On Amazon

This is the app-controlled step up. You can schedule or change feedings from your phone, and the 5L tank holds about 5 pounds of food. A low-food sensor tells you when to refill. It also records a short voice message, which some dogs respond to and some don't care about.

What makes it stand out: Over 10,000 reviews at 4.1 stars, plus 5G and 2.4G Wi-Fi, up to 10 meals a day, a desiccant bag and a twist-lock lid with a silicone seal.

Good to know: The listing gives a kibble range of 2 to 15mm, so big kibble may not fit. A lot of the lower reviews mention the app or Wi-Fi setup, so be ready to spend 15 minutes on it.

4. oneisall 3L Rechargeable WiFi Feeder

Best for: people with large kibble who want a battery-powered, app-controlled feeder.

Check Price On Amazon

It's a smaller 3L feeder with a clear tank, a numbered display and app control. Because it runs on its own battery, you can put it anywhere and don't need to hunt for an outlet. The original post said a full tank feeds a puppy for about 10 days.

What makes it stand out: A built-in rechargeable battery that the listing says lasts about 100 days, plus an app and a design made for large kibble.

Good to know: 3L is small for an adult dog, and 4.1 stars on about 770 reviews is the lowest rating among the kept picks. It's also listed as a cat feeder first.

5. Large Breed 12L / 50-Cup Dog Feeder with Camera

Best for: large dogs, multi-dog homes and long weekends away.

Check Price On Amazon

This is the one to look at if you actually own a big dog. The hopper is a lot larger than the others (about 50 cups), the dispensing path is made for large kibble (the listing mentions an anti-jam design and kibble up to 18mm) and the camera lets you check that dinner got eaten.

What makes it stand out: The size. The listing says a 12L tank holds 15 to 20 days of food for a big dog, and the photos show a built-in 1080P camera, Wi-Fi app control and a wide bowl.

Good to know: It's the most expensive pick here (around $100 at the time of writing) and the brand is not a well-known one. It has about 425 reviews, so there's less history than the 4L models. Check the return policy.

How to Set Up an Automatic Dog Feeder

  1. Work out your dog's daily amount from the food bag or your vet, then divide it by the number of meals.
  2. Run a test: set a portion, collect what comes out and weigh it. Portions vary a little by kibble shape.
  3. Start with the feeder in the room where your dog already eats, and run it beside the old bowl for a few days.
  4. Put in only a few days of food at first. Then you can watch for jams before you leave for a weekend.
  5. Wash the bowl and the food chute every week or two. Kibble oils build up and go stale.

Frequently Asked Questions

Are automatic feeders good for dogs?

They're good for dogs who eat on a schedule, especially if you work long days. They help with portion control, too. They don't replace time with your dog, and a very clever or food-obsessed dog may try to get into the hopper, so pick a feeder with a locking lid.

What is the best automatic dog feeder for large dogs?

For large dogs, pick a bigger tank (8L to 12L) and a feeder rated for large kibble. In this list that's the 12L large-breed model. The 4L models are better for small and medium dogs.

Can an automatic feeder work for wet food?

Not really. The feeders on this list are for dry kibble. Wet food spoils at room temperature, and the chutes aren't made for it. Some special wet-food feeders use ice packs, but they only keep food fresh for a few hours.

Can I use one automatic feeder for two dogs?

You can, but both dogs get the same portions from the same bowl, and the faster eater will often finish first. For dogs on different diets or sizes, use one feeder for each or feed them in separate rooms.

Final Thoughts

If you have a small or medium dog and want the safest buy, we'd go with the VOLUAS. It has the most reviews and a plain design that doesn't depend on Wi-Fi. If you want to control meals from your phone, the PETLIBRO Granary is the one to look at.

If you have a big dog or leave for long weekends, skip the 4L models and look at the 12L large-breed feeder. Just check the kibble size and return policy first.
