Best Automatic Dog Food Dispenser For Large Dogs vs Small Dogs


What Are Automatic Dog Food Dispensers and Feeders?

Automatic dog food dispensers are small machines that store dry dog food inside a hopper, and dispense the food automatically into a feeder tray in the amounts and intervals you program or set it to be dispensed.


What’s Good For You About An Automatic Dog Food Dispenser?

There are several benefits to having an automatic dog food dispenser:

You don’t have to fill your dog’s bowl as much – you save time and effort

If you aren’t home when it’s your dog’s feeding time (you might be at work or at the gym), the dispenser can automatically feed them as long as you’ve programmed it to

You can control when your dog gets fed

You can control how much your dog gets fed each time the dispensers releases food

They can be a great solution for slowing down dogs who eat too fast


Automatic Dog Food Dispensers For Small and Medium Dogs

The main difference between small dogs and big dogs is how much they eat per day.

The following are estimates of cups of dog food eaten per day for 10 to 50 lbs dogs:

10-20 lbs dog – 3/4 to 1 cup a day

20-50 lbs dog – 1 to 2 cups a day


Keep in mind that adult dogs eat around twice per day – once in the morning, and once at night.

One of the most popular automatic dog food dispensers, the Petsafe Automatic Dog Food Feeder (on Amazon), has a 24 cup capacity (roughly 5.6 litres)  

Based on a 2 cups a day feeding routine for say a 40 to 50 lbs dog, this feeder when fully filled will last an estimated 12 days before you need to re-fill it again.

Some of the other features of the Petsafe Automatic Dog Food Feeder (on Amazon) are:

It has a digital timer that you program yourself – up to 12 meals a day with flexible meal portions from 1/8 cup up to 4 cups

It has a Slow Feed Mode for fast eaters that dispenses meals greater than 1/8 cup over 15 minutes

There are also an Immediate Feed Mode that dispenses next scheduled meal instantly, and Pause Feed Mode that temporarily stops feeding without losing programmed feed schedule

It has a Pet-proof dispenser that helps keep your dog out of the hopper, and keeps food sealed and fresh

It comes with a removable stainless steel bowl 

It disassembles for easy cleaning with some dishwasher safe parts

You can operate it with 4 alkaline batteries or a power adapter sold separately


Automatic Dog Food Dispensers For Large Dogs

The following are estimates for 50 to 75 lbs + dogs in terms of how many cups of dog food they might eat per day:

50-75lbs dog – 2 to 3 cups per day

75+ lbs dog – 3 to 5 cups per day


These large breeds still eat twice a day.

We know from above that the PetSafe Automatic Feeder has a 24 cup capacity (roughly 5.6 litres).

But, there is also a larger capacity feeder like the Petfly Automatic Dog Food Feeder (on Amazon) that has a 10.6L food capacity, which holds around 44 cups at capacity. 

Based on a 4 cups a day feeding routine for say a 90lbs dog, the Petsafe feeder when fully filled will last an estimated 6 days before you need to re-fill it again.

The Petfly or a similar capacity automatic feeder will last around 11 days before needing to be re-filled.

Some of the other features of the Petfly Automatic Dog Food Feeder (on Amazon) are:

Can program using the LCD control panel on the feeder, and can control further functions with remote control

Can program to support feeding 1-5 meals per day, selecting 1-12 portions for each meal(each portion about 25g food)

Has a transparent hopper so you can see how much food is left

Hoppe holds 10.6 litres of dry dog food, which works out to be around double what the Petsafe dispenser holds

Built-in Voice Recorder so your pet can hear your voice when it feeds

Can power with either batteries or adpater

Dimensions: 16.5*9.8*14.5 inches 


Automatic Dog Food Dispensers For Puppies

Puppies need to eat smaller amounts more regularly – 3 to 4 times a day, compared to adults who are eating roughly twice a day.

Either of the above feeders will be ok for them.

Don’t forget, a large breed puppy turns into a big adult one day – so it might be worth getting a large capacity dispenser for a large breed puppy to allow for growth.


Other Food Dispensing Devices For Dogs

There are also pet security camera devices that allow you to interact with and dispense treats for your dog while you are not home.
