How Much to Feed a Australian Shepherd: Feeding Chart by Age and Weight

General nutrition information compiled from product labels and published sources, not veterinary advice. Your veterinarian is the right person to choose a diet for your dog, especially one with a health condition.

If you are wondering how much to feed a Australian Shepherd, the honest answer starts with the bag, not a number on a website. Every food has a different calorie density, so a cup of one formula can be a very different meal from a cup of another.

This guide shows you how to read a label feeding guide, set a starting amount, and adjust it by watching your dog. It also includes an Australian Shepherd feeding chart by age and weight, built from the calorie and feeding-guide data on real product pages.

One thing up front: label guides are starting points. A veterinarian sets the amount for an individual dog.

What you need

The bag or can of your dog's current food, with its feeding guide and calorie statement (kcal per cup).
A kitchen scale that reads in grams. Royal Canin notes that grams are the most accurate form of measurement, and that cup amounts are given to the closest proximity.
A standard measuring cup, if you do not weigh meals.
Your dog's current weight, from a home scale or your veterinarian's office.
A notebook or phone note for weight, amounts and body condition checks.
Your veterinarian's contact details, for the final decision.

Step 1: Know the size and life stage of your dog

Wikipedia lists the adult Australian Shepherd at 35 to 70 lb (16 to 32 kg). The Royal Canin breed library profile puts males at about 50 to 65 lb and females at about 40 to 55 lb. That is a wide spread, so two adult Aussies can need quite different amounts.

No source we use states a size category for the breed. Based on the weight range, most Aussies fit what many brands call a medium dog.

Royal Canin, a manufacturer rather than a veterinary or club source, divides the breed's life into these stages:

Puppy: birth to 12 months
Adult: 1 to 7 years
Mature: 7 to 10 years
Senior: from 10 years

Other brands draw the lines differently. Hill's, for example, sells large-breed adult formulas for 1 to 5 years and a 6+ formula. Use the stage the brand names on the bag you are actually feeding.

Step 2: Pick a food that matches the stage

The label's AAFCO statement tells you which life stage the food is built for. Look for "maintenance" (adult), "growth" (puppy) or "all life stages."

For puppies, Cornell University's Riney Canine Health Center advises a commercial large-breed puppy diet with an AAFCO growth adequacy statement and no extra calcium. Aussies are mostly under 70 lb as adults, so a general growth or all-life-stages food is the usual match. The large-size wording matters mainly for dogs at the top of the breed's range.

Here is the wording to watch for. Some labels say "including growth of large size dogs (70 lb. or more as an adult)." Victor's Hi-Pro Plus page says "except for growth of large size dogs (70 lb. or more as an adult)." That second wording means it is not meant as a large-breed puppy food. Check the exact wording on the bag, and ask your veterinarian if your puppy looks likely to be a big one.

For a side-by-side look at foods, see our label comparison of dog foods for Australian Shepherds. We compared label data only. We did not run feeding trials or taste tests.

Step 3: Find the calories and the feeding guide on your label

Find two things: the kcal per cup (or per can or pack) and the feeding table. The table below shows what several product pages state. Amounts differ because the foods differ.

Product (brand's own page)	Calories stated	How the label guide is organized
Royal Canin Medium Adult	340 kcal ME per cup (as fed, calculated)	For adults over 12 months, 23 to 55 lb. The page says it is only a guide.
Royal Canin Medium Puppy	410 kcal ME per cup (as fed, calculated)	Listed by puppy age in months and adult target weight, with a feeding calculator.
Royal Canin Medium Digestive Care	321 kcal ME per cup (as fed, calculated)	Daily chart by dog weight (26 to 53 lb) and activity level (low, medium, high).
Hill's Science Diet Adult Large Breed Chicken & Barley	365 kcal per cup (3675 kcal/kg)	For large-breed adults with an ideal weight of 55 to 110 lb. Adjust amounts to maintain optimal weight.
Hill's Science Diet Adult 6+ Large Breed	352 kcal per cup (3550 kcal/kg)	For large-breed dogs 6+ years, 55 to 110 lb. Adjust amounts to maintain optimal weight.
Victor Hi-Pro Plus	406 kcal per cup (3,815 kcal/kg)	High-protein formula for active dogs. The page says to add 1/2 cup for every 20 lb over 100 lb.
Victor Chicken Meal & Brown Rice	372 kcal per cup (3496 kcal/kg)	All life stages, normal activity. The page says to add 1/2 cup for every 20 lb over 100 lb.
Freshpet Home Cooked Chicken	189 kcal per cup (calculated ME); 770 kcal per lb	One meal daily or divided into two. You select your dog's weight to see the daily amount.
Nom Nom Chicken Cuisine	244 kcal per cup (calculated; 219 g cup)	Daily Feeding Guide for a full Nom Nom diet. The page says recommendations are only a guide and may vary.

Notice the spread. Freshpet's page states 189 kcal per cup, while Victor Hi-Pro Plus states 406. A cup of one is not a cup of the other, so never copy a cup amount from one brand to another.

Hill's gives typical nutrient values rather than guaranteed minimums, and the Hill's feeding pages here are written for large-breed dogs of 55 to 110 lb. A smaller Aussie falls below that range. Check the brand's own chart, or ask about a formula that fits your dog's size.

Step 4: Build your starting chart by age and weight

We cannot publish one cup amount per weight for the breed, because no source supports that. Here is how to set up your own chart instead.

Stage (Royal Canin breed library)	What to look for on the label	How to find the starting amount
Puppy, birth to 12 months	AAFCO growth statement (or all life stages). Royal Canin Medium Puppy lists amounts by age in months and adult target weight.	Use the row for your puppy's age and expected adult weight. Recheck as your puppy grows.
Adult, 1 to 7 years (about 40 to 65 lb for most Aussies)	AAFCO maintenance or all-life-stages statement.	Use the row for your dog's current weight and activity level.
Mature, 7 to 10 years	An adult or mature formula. Hill's has a 6+ large-breed recipe.	Start from the label row, then adjust by body condition.
Senior, from 10 years	A complete and balanced food suited to your dog's needs.	Review the amount with your veterinarian at each checkup.

For the weight row, use your dog's current weight, not a guess. If your dog is overweight, your veterinarian may suggest feeding for a target weight instead.

Step 5: Measure, split and record

Look up the daily amount on the label for your dog's weight.
Weigh it in grams if the label gives grams. Otherwise level a measuring cup.
Split the daily amount into meals. Many owners use two meals a day. Freshpet's page describes one meal or two for its recipe, so follow the brand's wording for your food.
Count treats and chews as part of the daily food, and trim meals a little to make room.
Write down the amount, the date and your dog's weight.

Step 6: Check body condition every couple of weeks

The scale shows weight, but body condition shows whether that weight is right for this dog. Vets commonly use a body condition score. Here is a simple home check:

Ribs: run your hands along the sides. You should feel the ribs under a thin layer of padding, without pressing hard. If you cannot find them, your dog may be carrying extra weight. If they stick out sharply, your dog may be too lean.
Waist: look down from above. A healthy outline usually narrows behind the ribs.
Tummy tuck: look from the side. The belly line should rise from the chest toward the hips rather than hang level or sag.

An Aussie's thick double coat can hide the outline, so use your hands as much as your eyes. Ask your veterinarian to show you what your dog's ideal condition feels like.

Step 7: Adjust by activity and by results

Aussies are working-type dogs, but pet dogs vary a lot. Royal Canin's Digestive Care chart, for example, gives different amounts for low, medium and high activity. That is a good reminder that two dogs of the same weight can eat differently.

Use this rhythm:

Feed the label starting amount for two to three weeks.
Weigh your dog and check body condition.
If your dog is gaining and the ribs are getting hard to feel, reduce the amount a little.
If your dog is losing weight without a plan, or feels bony, call your veterinarian before adding food.
Make small changes and recheck. Hill's feeding pages say to adjust amounts as necessary to maintain optimal weight.

A very active period, such as a season of herding, agility or long hikes, may call for more food. A quiet stretch may call for less. Higher-calorie foods need smaller portions. Victor Hi-Pro Plus, for instance, states 406 kcal per cup and is described as a high-protein formula for active dogs.

Tips

Switch foods slowly, mixing the new food into the old over about a week, unless your veterinarian says otherwise.
Keep the same measuring tool each time. Scoops vary.
Check the calorie statement whenever you change brands or formulas, even within one brand.
Wet food counts too. Royal Canin's Weight Care canned food lists 263 kcal ME per 13.5 oz can and is not stated per cup, so convert with care and ask your veterinarian.
Mention your dog's food and amount at every veterinary visit. Medication questions also matter for this breed, since the OFA describes multiple drug sensitivity (MDR1) as something to be aware of with Aussies. That is not a diet issue, but it is worth raising with your veterinarian.

Common mistakes to avoid

Copying cups between brands. As the table shows, calories per cup vary widely.
Treating the chart as a rule. The Nom Nom and Royal Canin pages both say their amounts are only a guide.
Feeding by the puppy's age and ignoring its weight. Growth varies. Recheck regularly.
Adding calcium or supplements to a puppy diet. Cornell advises no extra calcium for growing puppies on a complete large-breed puppy diet. Ask your veterinarian before adding anything.
Forgetting treats. They add up quickly in a small dog's day and a medium dog's too.
Assuming a food fixes a health problem. No food on this page is claimed to prevent or treat any condition. Prescription diets are something only a veterinarian prescribes.
Chasing marketing words. The AAFCO statement, ingredient list and calorie figure tell you more than the front of the bag.

What to expect

If the amount suits your dog, you may see steady weight, a visible waist, ribs you can feel with light pressure, and consistent energy for daily activity. Stools are often firm and regular on a well-matched diet. Results vary by dog, and these signs do not replace a veterinary exam.

Most owners find the first amount needs a small tweak after a few weeks. That is normal. If your dog's weight, appetite or stools change suddenly, contact your veterinarian rather than waiting.

The FDA has also investigated a possible link between certain diets and canine dilated cardiomyopathy (DCM). Its latest update is dated December 23, 2022, and the agency says it will not issue further public updates until there is meaningful new scientific information. The FDA does not treat report numbers as proof of cause. If you have questions about your dog's diet and heart health, ask your veterinarian.

The bottom line

How much should a Australian Shepherd eat? It depends on age, current weight, activity and the specific food. Use the label's guide as a starting point, measure carefully, check body condition, and adjust in small steps. Your veterinarian sets the amount for your individual dog.
