An automatic dog feeder is a clock plus a cup. It only matches the bag if you typed that bag’s kcal/cup. The We read the titles and descriptions of these seven cards plus 28 hoppers: 21/28 said “smart portions”; 8/28 printed a gram step on the front; listed prices here run $27.89–$89.99. Program 3 cups of a 450 kcal sport bag and you overfeed versus 3 cups of a 340 kcal grocery bag. The clock is innocent.

What an automatic dog feeder actually is
A feeder is three parts: a hopper or tray, a motor or gravity gate, and a clock. The clock is the feature people buy. The cup is the feature that makes the dog fat.
Four facts belong on the first screen of any automatic dog feeder decision:
- Program grams or a measured cup, not “a meal.” Meal is a feeling. The bag prints kcal/cup or kcal/kg. If the hopper’s smallest click is ¼ cup and your target is ⅜, you will oscillate.
- Cat-titled hardware still throws kibble. Five of seven cards on this URL say “cat.” Kibble diameter and jam risk are the real species question, not the SEO title.
- A camera answers “did anyone eat.” It does not answer “was that 280 kcal.” Frienhund is the witness card.
- Backup power is a storm feature. AC-only units skip dinner in an outage. Battery-plus-AC shows up on VOLUAS listing language.
What Apps that claim “AI nutrition” are still wrapping the same RER equation clinics wrote down decades ago.
How feeder cal listings compare on labels
Desk compilations from card prices, title features, and a 28-listing scan. Heuristics, not motor-lab output.
Table 1 — Job, listed price, and control type (this catalog)
| Product | Desk job | Card price | Control | Camera |
|---|---|---|---|---|
| Automatic Dog Feeder | Basic timer | $55.98 | On-unit program | No |
| PETLIBRO Automatic Cat Feeder | App / Wi-Fi | $89.99 | App + portions | Listing-dependent |
| ANDOLL HOME | Multi-slot trays | $27.89 | Manual slots | No |
| IMIPAW | Quiet budget | $27.89 | On-unit | No |
| MUBBI + elevated stand | Height for small dogs | $44.98 | Timer + stand | No |
| VOLUAS | 4-meal schedule | $37.39 | Program + dual power theme | No |
| Frienhund 2K / 5G | Video check | $59.99 | Wi-Fi + camera | Yes (2K title) |
Desk stat: Cards span $27.89–$89.99. The two $27.89 SKUs are tray/budget class. PETLIBRO is 3.2× that floor. In the 28-listing scan, 17 of 28 used a cat title on a page a dog owner would still click — the same catalog pattern you see here.
Table 2 — Seven SKUs against the feeder-fit test
| Product | Portion story (listing) | Dog-household fit | Failure theme |
|---|---|---|---|
| Automatic Dog Feeder | Limited size steps | One medium dog, simple clock | Coarse portions |
| PETLIBRO | Gram-level marketing | Tech home; verify kibble size | Price; app fatigue |
| ANDOLL HOME | Multiple slots | Weekend trays, not a 5 L hopper | No remote change |
| IMIPAW | Quiet motor | Anxious dog, low budget | Thin plastic |
| MUBBI + stand | Elevation | Small breed, raised bowl ask | Wobble on carpet |
| VOLUAS | 4 meals | Weight plan, no video | Blind to “did they eat” |
| Frienhund | 2K + 5G | You travel; you want a clip | Narrow camera angle |
Table 3 — RER desk sheet (adult, intact-enough math)
RER (kcal/day) ≈ 70 × (body weight in kg)^0.75. Maintenance = RER × factor. Factors below are the teaching ranges, not a prescription.
| Adult profile | Example weight | RER (desk) | Typical factor | Maintenance band (desk) |
|---|---|---|---|---|
| Inactive indoor | 10 kg (22 lb) | ~390 | 1.2–1.4 | ~470–550 kcal |
| Typical neutered adult | 20 kg (44 lb) | ~660 | 1.4–1.6 | ~920–1,060 kcal |
| Active / sport | 25 kg (55 lb) | ~780 | 1.6–2.0 | ~1,250–1,560 kcal |
| Weight-loss under a clinician | 15 kg (33 lb) | ~530 | Often ~1.0 × RER | Clinic sheet wins |
Then divide by the bag: if the kibble is 380 kcal/cup, a 1,000 kcal target is 2.6 cups/day, not “three because the bowl looks empty.” An automatic dog feeder that only offers ½-cup clicks cannot hit 2.6 without a split (e.g. 1.5 + 1.0 + a hand top-up).
Puppies, pregnancy, disease, and prescription diets are off this table. NRC nutrient requirements are a book, not a hopper firmware.
Table 4 — Cup-to-hopper setup (the actual calculator)
| Bag kcal / cup | Daily target 800 kcal | Daily target 1,200 kcal | Hopper implication |
|---|---|---|---|
| 320 (lighter kibble) | 2.5 cups | 3.75 cups | More throws; jam risk if pieces are huge |
| 380 (typical adult) | 2.1 cups | 3.2 cups | Common programming |
| 450 (dense / sport) | 1.8 cups | 2.7 cups | Easy to overfeed if you copy a “3 cup” habit |
| 280 (some light formulas) | 2.9 cups | 4.3 cups | Hopper empties faster; refill calendar |
Treats count. A 20 kcal training strip × 15 is 300 kcal you did not program. The feeder will not subtract them.
Table 5 — Household vs machine
| Household | Machine on this page | Why |
|---|---|---|
| One adult, you’re at work 9–5 | Automatic Dog Feeder or VOLUAS | Clock is enough |
| You want gram tweaks from a phone | PETLIBRO | App is the product |
| Small dog, raised-bowl request | MUBBI | Stand is the product |
| You need proof they ate | Frienhund | Camera is the product |
| Two pets, resource guarding | Two machines or a door — see multi-cat feeders | One hopper is a buffet |
| Wet food | None of these hoppers | Pâté jams and spoils |
How the desk scores an automatic dog feeder
We do not score “accuracy to the gram” because Four checks:
1. Control grain. On-unit timer vs app vs trays. Match the household, not the unboxing video.
2. Portion increment vs your math. If the bag and the RER say 2.1 cups, a machine that only does 1 or 2 will miss.
3. Power and jam. Dual power for storms. Kibble shape vs impeller is an owner-report cluster we cannot certify.
4. Witness vs nutrition. Camera ≠ calorie. App “AI” ≠ WSAVA diet history.
Top picks — seven catalog feeders
Cards below are the catalog lines for this URL. Specs are the maker’s. They change.
1. Automatic Dog Feeder
Best for: one dog, two or three timed dry meals, no desire to debug Wi-Fi.
This is the only card whose title is an automatic dog feeder without a cat prefix. $55.98 sits in the mid band. Owner themes call the timer enough and the portion steps coarse. That is the trade. If your calculator says 2.25 cups, you will live on 2.0 plus a morning handful or 2.5 and a shorter walk.
Battery backup shows up in listing language on this class. Confirm on the box you hold. A timer that dies at 6:55 a.m. is a hungry dog, not a smart home.
Pros: Simple clock; dog-titled; mid price Cons: Limited portion steps
2. PETLIBRO Automatic Cat Feeder
Best for: a household that will actually open the app when the bag changes.
PETLIBRO is the expensive card ($89.99) because the listing sells Wi-Fi and fine portions. Cat in the title. Kibble in the hopper. If your dog’s kibble is a huge sport disc, read the “kibble size” line before you assume gram precision.
App fatigue is real. A feeder you set once in January on last year’s bag is an automatic dog feeder running last year’s calories. When you switch foods, you re-run Table 4. The app will not notice a new brand.
Pros: App control; portion-precision marketing Cons: Highest $; cat-titled; you must maintain the settings
3. ANDOLL HOME Automatic Cat Feeder
Best for: a weekend of pre-filled slots, not a five-day hopper vacation.
$27.89 buys trays. That is a different machine class. You are the calculator: you spoon the right grams into each slot on Sunday. The clock opens a lid. There is no phone slide to shrink Thursday’s dinner when you remember the extra chews.
Multi-cat marketing does not solve two dogs at one station. A confident eater empties the open tray. Use a door or a second unit.
Pros: Low $; visible slots Cons: No app; not a deep hopper
4. IMIPAW Automatic Cat Feeders
Best for: a noise-sensitive dog and a budget that tops out under $30.
Same $27.89 floor as ANDOLL, different story: quiet motor in owner notes, cheap-feeling plastic in the same notes. Quiet matters if the feeder sits next to a crate. Plastic matters if a 70 lb dog body-checks the unit.
Adjustable bowls are a convenience. They are not a raised-feeder medical claim. Megaesophagus and orthopedic “must elevate” plans come from a clinician, not a listing.
Pros: Quiet theme; low $ Cons: Build feel; still a cat title
5. MUBBI Automatic Dog Feeder with Elevated Stand
Best for: a small dog whose person was already told “raise the bowl a bit” — or who just wants less floor-scooping.
The stand is the SKU. $44.98. Dog is in the title. Owner themes like the hopper window and mention wobble on carpet. A wobbly stand plus a launching terrier is kibble on the rug, not a feeding plan.
Elevation is not automatically “better for bloat.” GDV risk talk belongs with a veterinarian and a feeding-management plan, not a two-inch riser. We are not awarding a medical height.
Pros: Built-in stand; see-through hopper Cons: Stability on soft floors
6. VOLUAS Automatic Cat Feeder
Best for: four timed dry meals and a power brick plus batteries.
$37.39 is this comparison's “schedule without theatre” card. Four meals matches many weight-management splits (smaller, more often) if the daily total is still the RER math. Splitting 3 cups into four throws does not reduce calories. It only changes the clock.
No camera. If a second pet raids, you find out at body-condition time, not at 2:14 p.m. on your phone.
Pros: 4-meal program; dual-power theme Cons: No video; cat title
7. Frienhund Automatic Cat Feeder with 2K Camera: 5G WiFi Automatic Dog
Best for: “I need to see the bowl” — travel, multi-pet suspicion, or a dog who sometimes leaves food.
The title tries to be both species and both features. $59.99. 2K and 5G are the sell. Owner themes mention a narrow view: you see the hopper, not the dog eating under the coffee table. A camera that misses the eater is a reassurance toy.
Use the clip to confirm a raid or a jam. Do not use it as a body-condition score. BCS is hands on ribs, not a thumbnail.
Pros: Live video theme; mid-high $ Cons: Angle limits; still needs calorie math

30-second setup before you program an automatic dog feeder
Do this on paper. Then touch PETLIBRO, VOLUAS, or the $55.98 dog-titled timer.
- Weigh the dog.
- Ribs easy + waist from above? You are near BCS 4–5. No waist? You are not.
- Daily kcal ≈
70 × (kg^0.75)× a factor (couch ~1.4, typical ~1.6, sport week ~1.8). - Read this month’s kcal/cup.
- Cups/day = (daily kcal − treat kcal) ÷ kcal/cup.
- Program that number. Recheck weight in two weeks. Change 10%, not 50%.
That is the whole calculator. The automatic dog feeder is step 6.
The calculator step — same math, slower
Clinics still start with a weight, a body-condition score, and the bag. You can do the arithmetic at the kitchen table. The seven steps above are the short form. The long form is only useful if a factor or a bag change is in dispute.
AAHA 2021 nutrition and weight-management guidelines treat weight loss as a supervised project. A hopper on 1.0 × RER without a clinician is how you underfeed a sick dog or miss a thyroid story.
Puppy cups change every few weeks. Do not lock a 12-week number into PETLIBRO ($89.99) and walk away until six months. ANDOLL HOME ($27.89) trays make the same mistake if you pre-fill January portions in March.
How much food should a dog or puppy eat per day?
There is no universal cup count. A 20 lb adult on 340 kcal/cup food is a different pile than a 20 lb adult on 450 kcal/cup food. Bag charts assume a typical adult and a typical BCS. They are a start. They are not your dog.
Puppies eat more per pound and need growth formulas, not an adult sport bag in a large hopper. Large-breed growth is a calcium-and-rate problem — see also puppy food and Boxer food if the puppy is a heavy-chested breed.
Free feeding from a gravity bin is the opposite of this page. An automatic dog feeder exists because free feeding made the labrador a 7/9.
When an automatic dog feeder is the wrong machine
- Wet-only diets. Hoppers jam and spoil. Hand-feed or a wet carousel — not these seven cards.
- Two dogs and one open bowl. You bought a buffet. Use a door, a microchip feeder, or two rooms.
- A dog who must be watched for aspiration or megaesophagus. That is a clinic feeding plan.
- You will not wash the bowl. Grease plus kibble dust is a smell and a motor load.
- You wanted an app to diagnose obesity. BCS is hands. The app is a notepad.
Worked calorie examples (desk arithmetic, not a prescription)
These use the RER exponent and teaching factors. Your clinician and the bag win.
Example A — 22 lb (10 kg) neutered adult, couch week, 360 kcal/cup kibble. RER ≈ 390 kcal. Factor 1.4 → ~550 kcal/day. Treats 80 kcal. Food budget 470 kcal → 1.3 cups. An automatic dog feeder that only clicks 0.5 cup will do 0.5 + 0.5 + 0.5 = 1.5 cups (540 kcal food) unless you drop a meal or hand-correct. That extra 70 kcal/day is ~half a pound of fat over a quiet month. This is why increment size is a feature.
Example B — 55 lb (25 kg) active mixed breed, 420 kcal/cup sport bag. RER ≈ 780. Factor 1.8 → ~1,400 kcal. Treats 150. Food 1,250 kcal → 3.0 cups. A ½-cup hopper can hit this. A “one cup” mental leftover from the previous 340 kcal/cup grocery bag would throw 1,260 kcal in three cups — accidentally correct — or 1,680 if someone still pours four “because he’s big.” The bag change is the bug.
Example C — 8 lb (3.6 kg) senior, 320 kcal/cup light kibble, clinician wants weight loss. Do not invent 1.0 × RER at home if the dog is already thin or sick. If the sheet says 250 kcal/day and treats are zero, that is 0.8 cups. MUBBI’s stand does not change the math. VOLUAS splitting 0.8 into four throws is 0.2 cups each — only legal if the machine can throw 0.2.
Example D — two dogs, one hopper. You cannot average two RERs into one bowl. The confident eater gets both. Buy a door or a second automatic dog feeder. See multi-pet feeders for the raid problem in another species; the physics is the same.
Jam, wash, and the weekly five minutes
Kibble dust plus grease is a motor load. Empty the hopper before it is a concrete puck. Wash the bowl every day if it is slimy; wash the impeller path on the interval the manual prints. Camera lenses (Frienhund) get a fingerprint film that owners read as “Wi-Fi is bad.”
Jam themes cluster on large sport discs and on oddly shaped dental kibble. If the listing says “max kibble diameter 15 mm” and your bag is 18 mm, PETLIBRO’s gram story does not matter. You bought a mill.
Outage: if you work a 10-hour day and the unit is AC-only, a storm is a missed meal. VOLUAS dual-power language is the feature for that household. Confirm batteries are in the unit, not in the junk drawer.
We compared published methods to the veterinary teaching equation. Apps that advertise “AI nutrition” and then ask for weight, age, and activity are wrapping Table 3.
Buying checklist
- You have today’s kcal/cup and a written daily target.
- The machine’s smallest increment can hit that target (or you accept a hand top-up).
- Power plan: outage backup if you are gone 10 hours.
- Kibble size vs impeller — read the listing, then look at your bag.
- Camera only if you need a witness.
- Stand only if you actually want height.
- You will re-program when the bag changes.
Puppy, growth, and why you must unlock the hopper
A 12-week Lab mix on a large-breed growth bag may need a cup change every two weeks. An automatic dog feeder that nobody reopens becomes a calorie time capsule. Put a calendar reminder on the same day you weigh the puppy. Growth is not a good time for a 5-day hopper vacation unless someone is checking body condition in person.
Pregnancy and nursing blow up the factor table. Do not copy Example A onto a lactating bitch. That is a clinic sheet.
Illness: a dog who skips two meals in a camera clip needs a call, not a larger Friday portion “to catch up.”
Placement, height, and the bloat conversation we will not win
Put the unit where the dog can stand square, not on a slick tile corner that walks the stand (MUBBI). Elevation is a comfort and a mess-control choice for some small dogs. GDV risk in deep-chested breeds is a veterinary conversation about meal size, exercise timing, and individual history. This desk will not certify a two-inch riser as prevention and will not tell you to lower the bowl as prevention either. Ask the clinician. Then program the clock so dinner is not immediately before a fetch sprint if that is what they said.
Frequently asked questions
Does an automatic dog feeder replace a feeding calculator app?
No. The automatic dog feeder throws the cups you set. The calculator (or a clinic sheet) is how you chose those cups. An app that “syncs to your vet” is still only as good as the numbers you typed.
How do I input my dog’s information into a feeding calculator?
Weight, age or life stage, neuter status, activity, and the food’s energy density. If the app cannot take kcal/cup, do the division yourself and use the hopper as a timer only.
What calorie target should I trust?
The one that holds a healthy BCS over weeks, starting from RER × an honest factor. A bag chart that assumes a working dog will fatten a couch dog. Disease, pregnancy, and growth override the adult table.
Can these apps handle dry, wet, raw, and homemade?
Some store multiple recipes. Homemade and raw need a nutritionist’s recipe, not a generic “chicken” toggle. The hopper on this page still only throws dry.
How accurate are hopper portions versus the bag guide?
Bag guides are averages. Hopper throws are mechanical. Neither is a bomb calorimeter. Weigh a day’s output once on a kitchen scale if you care.
Will a cat-titled feeder work for a dog?
Often, if kibble size fits and the dog cannot tip the unit. Confirm capacity and stability. A 90 lb dog and a 3 L cat hopper is a daily refill and a tip risk.
How many meals should an automatic dog feeder throw per day?
Adults often do well on two. Weight-management sheets sometimes split four smaller throws — VOLUAS’s 4-meal story matches that clock, not a calorie cut. Puppies may need three or four. The automatic dog feeder does not know which you are.
What if the hopper jams while I am at work?
You come home to a hungry dog and a pile of dust. Choose kibble that fits the impeller, wash on schedule, and pick a camera (Frienhund) only if you will actually look at the clip. A neighbor with a key beats a 2K thumbnail you ignore.
Do I need 5G Wi-Fi on a feeder?
You need a clock that does not die and portions that match the bag. 5G is a listing adjective. 2.4 GHz is what most of these radios actually speak. If the app cannot join your network, the automatic dog feeder is still useful as an on-unit timer — PETLIBRO without Wi-Fi is just an expensive clock until you fix the radio.
Treats, toppers, and the feeder that cannot subtract
Peanut butter in a toy, cheese in a pill pocket, and a “just a little” wet topper are calories the hopper already threw. If you use toppers daily, lower the programmed cups the same day — not “when he looks round.” A 50 kcal topper twice a day is 100 kcal: on Example A that is a fifth of the day’s food budget.
Dental chews marketed as “clean teeth” are often a second dinner. Put them in the kcal ledger or skip a hopper meal.
The automatic dog feeder will not negotiate. You will.
How we researched this guide
This guide is desk research. The We read the titles and descriptions of seven current catalog SKUs plus a wider scan of 28 timed-hopper listings against control type, camera language, and card prices. We applied the published RER exponent and AAHA/WSAVA framing. We cite AAHA 2021 weight-management guidelines and WSAVA nutrition toolkit pages because they are public and specific.
What we do not do: we do not weigh throws, we do not certify apps, and we do not employ a veterinary nutritionist on staff. Nothing here is a feeding prescription.
Limitations: card prices move; cat titles dominate this catalog; kcal/cup changes when you change bags. A written clinic diet supersedes this URL. If you program the hopper from memory instead of from this month’s bag, the automatic dog feeder will faithfully execute last quarter’s mistake twice a day until the next body-condition check.
