# Australian Shepherd Feeding Guide: Calorie Targets & Sensitive Stomach Food
## Key Takeaways
- Adult Australian Shepherds typically require 900-1,400 kilocalories (kcal) daily, with precise needs varying significantly based on age, neuter status, and workload, necessitating regular body condition scoring for accurate adjustment.
- Digestive sensitivity in Australian Shepherds is often managed through a veterinary-guided elimination diet trial using single novel or hydrolyzed protein sources to identify and avoid specific food intolerances or allergies.
- The MDR1 gene mutation, prevalent in Australian Shepherds, poses a critical risk for severe adverse reactions to certain medications (e.g., loperamide), mandating veterinary consultation before administering any over-the-counter treatments for gastrointestinal upset.
- For puppies, a growth formula meeting AAFCO standards is crucial, with feeding frequency transitioning from 3-4 meals daily (8-16 weeks) to 2 meals daily (adolescent stage) to support healthy development without overfeeding.
- Senior Australian Shepherds may benefit from diets lower in fat but higher in easily digestible fiber and quality protein to manage slower metabolism, maintain muscle mass, and support gut motility.
- Acute gastrointestinal upset can be temporarily managed with a bland diet (e.g., boiled chicken and white rice), but this is not nutritionally complete and prolonged use or feeding without veterinary diagnosis can be detrimental.

If you own an Australian Shepherd, you need a feeding plan that matches their high energy output and their known tendency toward digestive sensitivity. The direct answer is that most adult Australian Shepherds need between 900 and 1,400 kilocalories per day, but that number shifts with age, neuter status, and work level. For dogs with sensitive stomachs, the priority is a highly digestible diet with a single novel or hydrolyzed protein source, introduced through a strict elimination trial.
This guide is educational and is not a substitute for veterinary diagnosis or treatment. Always consult your veterinarian or veterinary surgeon before changing your [dog](/knowledge/veterinary-medicine/clinical-methods/dog)'s diet, especially if they have chronic vomiting, diarrhoea (or diarrhea), or weight loss.
## At a Glance: Australian Shepherd Feeding Targets
The table below provides a starting point for healthy Australian Shepherds. These are estimates based on standard veterinary nutritional guidelines. Individual needs vary by 10% to 20% in either direction.
| Life Stage | Body Weight Range | Daily Calorie Target | Meals Per Day | Key Nutritional Focus |
| :--- | :--- | :--- | :--- | :--- |
| Puppy (8-16 weeks) | 5-15 lb (2.5-7 kg) | 400-700 kcal | 3-4 | Growth formula, DHA, controlled calcium |
| Puppy (4-8 months) | 15-35 lb (7-16 kg) | 700-1,100 kcal | 3 | Growth formula, moderate fat |
| Adolescent (8-12 months) | 35-50 lb (16-23 kg) | 1,000-1,400 kcal | 2 | Transition to adult food |
| Adult (Active Pet) | 40-55 lb (18-25 kg) | 1,000-1,300 kcal | 2 | High-quality protein, balanced omega-3 |
| Adult (Working/Agility) | 40-55 lb (18-25 kg) | 1,300-1,800 kcal | 2-3 | High fat, high protein, easy digestion |
| Senior (7+ years) | 40-55 lb (18-25 kg) | 800-1,100 kcal | 2 | Lower fat, high fiber, joint support |
**Source note:** These calorie ranges are derived from general veterinary nutritional calculations for active herding breeds, not from a specific breed study. The Merck Veterinary Manual provides foundational guidance on canine energy requirements and body condition scoring.
## Understanding the Australian Shepherd's Nutritional Physiology
The Australian Shepherd is a herding dog developed in the western United States, despite the name. They are known for high intelligence, intense work ethic, and remarkable endurance. This history shapes their nutritional needs.
### High Energy Expenditure
Australian Shepherds are not couch potatoes. A pet Australian Shepherd requires significant daily exercise, typically 60 to 90 minutes of vigorous activity. Working dogs on farms or in competitive sports like agility, flyball, or herding trials burn substantially more calories. The Merck Veterinary Manual states that working dogs can require 1.5 to 2 times the maintenance energy of a pet dog of the same size. This is why a blanket calorie recommendation fails. You must adjust intake based on body condition score and workload.
### The "Sensitive Stomach" Predisposition
Many Australian Shepherd owners report frequent digestive upsets. While there is no single peer-reviewed study confirming a genetic predisposition to inflammatory bowel disease (IBD) or food allergies specifically in this breed, clinical experience and veterinary resources acknowledge that herding breeds often present with chronic gastrointestinal signs. The Merck Veterinary Manual outlines that food-responsive enteropathies and adverse food reactions are common causes of chronic vomiting and diarrhoea in dogs. The Australian Shepherd's high energy and stress levels can also contribute to digestive issues, as stress is a known trigger for gastrointestinal motility problems.
### The Genetic Factor: The MDR1 Gene
A critical breed-specific consideration is the MDR1 gene mutation (also called ABCB1). This mutation affects drug transport and can cause severe reactions to certain medications like ivermectin and loperamide (Imodium). While this is primarily a drug sensitivity issue, it has nutritional implications. If your Australian Shepherd has the MDR1 mutation, you must be extremely cautious with any over-the-counter anti-diarrheal medications. The VCA Animal Hospitals explicitly warn against using certain medications in MDR1-positive dogs, and this should be a primary discussion with your veterinarian before any treatment for stomach upset. Do not use loperamide for diarrhoea in an Australian Shepherd without a negative MDR1 test and veterinary approval.
## Calorie Targets: A Detailed Breakdown
Calculating the right calorie target is the first step in preventing obesity and malnutrition. Obesity is a major health concern in dogs, leading to joint issues, diabetes, and reduced lifespan. The Association for Pet Obesity Prevention (APOP) data, referenced in veterinary guidelines, suggests over 50% of dogs are overweight. The Australian Shepherd is a working breed that can easily become overweight if their food intake is not matched to their activity.
### The Resting Energy Requirement (RER) Formula
Veterinarians use a standard formula to calculate a dog's baseline energy needs. The RER is calculated as 70 x (body weight in kg)^0.75. This gives the kilocalories needed at rest. For a 45 lb (20.4 kg) Australian Shepherd, the RER is approximately 650 kcal.
### Maintenance Energy Requirement (MER)
The MER is the RER multiplied by a factor based on life stage and activity:
- **Neutered adult:** 1.6 x RER (approx. 1,040 kcal)
- **Intact adult:** 1.8 x RER (approx. 1,170 kcal)
- **Active working dog:** 2.0 to 5.0 x RER (approx. 1,300 to 3,250 kcal)
- **Weight loss target:** 1.0 x RER (approx. 650 kcal)
These calculations align with the general feeding guidelines provided in the Merck Veterinary Manual and standard veterinary nutrition texts. The exact number on the food bag is a starting point. The most reliable method is to monitor body condition score (BCS) every two weeks and adjust portions by 10% increments.
### Puppy Calorie Needs
Australian Shepherd puppies grow rapidly. They need more calories per pound of body weight than adults because they are building bone and muscle. However, overfeeding large-breed puppies can lead to developmental orthopedic disease. The Australian Shepherd is a medium-sized breed, but they are prone to hip and elbow dysplasia. The current veterinary consensus, supported by the World Small Animal Veterinary Association (WSAVA) guidelines, recommends feeding a growth formula that meets AAFCO standards for growth. You should feed three to four meals a day until six months of age, then transition to two meals.
### Senior Adjustments
As Australian Shepherds age, their metabolism slows and they often lose lean muscle mass. The Merck Veterinary Manual highlights that older dogs may require fewer calories but more high-quality protein to maintain muscle. A senior Australian Shepherd with a sensitive stomach may benefit from a diet that is lower in fat but higher in easily digestible fiber to manage weight and gut motility.
## Sensitive Stomach Food: What Does the Science Say?
A "sensitive stomach" is a lay term for a dog that frequently vomits, has soft stool, or shows signs of gastrointestinal discomfort. The veterinary approach is to identify the underlying cause, not just to buy a random "sensitive stomach" formula.
### Causes of Chronic Digestive Upset
1. **Dietary Indiscretion:** Eating garbage, table scraps, or foreign objects. This is the most common cause of acute vomiting and diarrhoea in dogs, according to VCA Animal Hospitals.
2. **Adverse Food Reaction (Food Allergy or Intolerance):** True food allergies (immune-mediated) are less common than food intolerances (non-immune). Common triggers include beef, dairy, chicken, and wheat.
3. **Inflammatory Bowel Disease (IBD):** A chronic condition characterized by inflammation in the gut lining. Diagnosis requires a biopsy, but it is often managed with diet and medication.
4. **Pancreatitis:** Inflammation of the pancreas, often triggered by high-fat diets. This is a painful and serious condition.
5. **Stress and Anxiety:** Australian Shepherds are highly sensitive to their environment. Changes in routine, separation anxiety, or high-intensity training can cause stress-induced colitis.
### The Evidence-Based Approach: Elimination Diet
The gold standard for diagnosing a food adverse reaction is the elimination diet trial. This involves feeding a diet with a single novel protein (a protein the dog has never eaten, like kangaroo, rabbit, or venison) and a single carbohydrate source for 8 to 12 weeks. If the dog's symptoms resolve, a food challenge is performed to identify the offending ingredient. The Merck Veterinary Manual describes this as the only reliable way to diagnose food allergies.
### Hydrolyzed Protein Diets
For dogs with severe reactions or those who cannot tolerate novel proteins, hydrolyzed protein diets are recommended. In these diets, the protein molecules are broken down into smaller pieces that are less likely to trigger an immune response. These are typically prescription diets available through your veterinarian. They are highly digestible and are a cornerstone of managing IBD and food allergies.
### What to Look For in a Commercial Food
If your veterinarian recommends a commercial diet for a sensitive stomach, look for these characteristics:
- **Single protein source:** Avoid foods with multiple meat meals (chicken, beef, fish) as this increases the risk of reactions.
- **Highly digestible carbohydrates:** White rice, potato, or tapioca are easier on the gut than corn or wheat.
- **Moderate fat content:** High fat is a common trigger for pancreatitis and loose stools. Look for a fat content around 12-15% on a dry matter basis.
- **Added fiber:** Prebiotic fiber like beet pulp or fructooligosaccharides (FOS) can help firm up stool.
- **Omega-3 fatty acids:** These have anti-inflammatory properties and can support gut health.
### The "Bland Diet" for Acute Upset
For an acute episode of vomiting or diarrhoea (lasting less than 24 hours), a bland diet of boiled chicken (no skin) and white rice is a common home remedy. However, the VCA Animal Hospitals caution that this diet is not nutritionally complete and should only be used for a day or two. Prolonged feeding of a bland diet can lead to nutritional deficiencies. Also, if your Australian Shepherd has a chicken allergy, this will make things worse. A safer alternative is a prescription gastrointestinal diet from your vet.
## Regional and Regulatory Considerations
[Pet food](/knowledge/veterinary-medicine/nutrition/pet-food) regulations vary by region, and it is helpful to understand the standards in your country.
### North America (US and Canada)
In the United States, the Food and Drug Administration (FDA) regulates [pet food](/knowledge/veterinary-medicine/nutrition/pet-food), and the Association of American Feed Control Officials (AAFCO) establishes nutritional standards. The American Veterinary Medical Association (AVMA) supports the use of AAFCO standards to ensure pet foods are complete and balanced. In Canada, the Canadian Food Inspection Agency (CFIA) oversees pet [food safety](/knowledge/bacteria/livestock-bacteria/cooking-chicken-bacteria-prevention) and labeling, and they also rely on AAFCO guidelines. The Canadian Veterinary Medical Association (CVMA) advises pet owners to look for foods that meet AAFCO standards.
### Europe
In the European Union, [pet food](/knowledge/veterinary-medicine/nutrition/pet-food) is regulated by the European Food Safety Authority (EFSA) and the European Commission. The Federation of Veterinarians of Europe (FVE) emphasizes that pet food must be safe and nutritionally adequate. European regulations are often stricter regarding labeling and ingredient sourcing. When choosing a food in Europe, look for the "FEDIAF" (European Pet Food Industry Federation) nutritional guidelines label, which indicates the food meets European standards.
### Australia
In Australia, the Australian Competition and Consumer Commission (ACCC) and the Department of Agriculture, Fisheries and Forestry (DAFF) regulate pet food. The Australian Veterinary Association (AVA) recommends choosing a pet food that is manufactured by a reputable company and meets the Australian Standard for the manufacturing and marketing of pet food (AS 5812:2017). This standard is voluntary but is considered the benchmark for quality.
## Managing the Australian Shepherd's Sensitive Stomach: A Practical Protocol
### Step 1: Veterinary Examination
Before changing your dog's diet, a veterinary exam is essential. Your vet will rule out parasites, infections, and systemic diseases. The Companion Animal Parasite Council (CAPC) guidelines recommend regular fecal testing to rule out [intestinal parasites](/knowledge/parasites/pet-parasites/intestinal-parasites-dogs-cats-identification-treatment), which are a common cause of diarrhoea in dogs. A simple fecal exam can prevent months of unnecessary diet trials.
### Step 2: The Elimination Trial
If parasites are ruled out, your vet may recommend a prescription hydrolyzed protein diet or a novel protein diet. This diet must be fed exclusively for 8 to 12 weeks. No treats, no table scraps, no flavored medications. This is the only way to get a clear answer.
### Step 3: Reintroduction and Maintenance
If symptoms resolve, you can slowly reintroduce ingredients one at a time to identify triggers. Once identified, you will need to find a long-term diet that avoids those ingredients. Many owners find that a limited-ingredient diet (LID) from a reputable brand works well for maintenance.
### Step 4: Probiotics and Gut Health
The use of probiotics in dogs with gastrointestinal disease is supported by emerging veterinary research. The Merck Veterinary Manual notes that probiotics may help restore normal gut flora and reduce inflammation. Look for a probiotic specifically formulated for dogs, with a guaranteed number of colony-forming units (CFUs). Discuss the right product with your vet, as not all probiotics are effective.
## Unsafe Home Remedies and Common Mistakes
- **Do not give loperamide (Imodium):** As mentioned, this is dangerous in MDR1-positive Australian Shepherds. It can cause severe neurological signs.
- **Do not give human anti-nausea medications:** Medications like Pepto-Bismol (bismuth subsalicylate) can be toxic to dogs, especially in high doses.
- **Do not feed raw diets without veterinary guidance:** Raw diets are a hot topic. While some owners report benefits, the AVMA and the American Animal Hospital Association (AAHA) discourage feeding raw or undercooked animal-source protein due to the risk of bacterial contamination like Salmonella and Listeria. This risk is especially high for dogs with sensitive stomachs, whose gut barrier may already be compromised.
- **Do not switch foods abruptly:** Sudden diet changes can cause gastroenteritis. Always transition over 7 to 10 days, mixing increasing amounts of the new food with the old.
- **Do not ignore chronic symptoms:** If your dog has soft stool for more than a few days, or if they are losing weight, this is not just a "sensitive stomach." This requires a veterinary diagnosis.
## Prevention: Building a Healthy Gut from Puppyhood
Preventing digestive issues is easier than treating them. For Australian Shepherd puppies, focus on the following:
1. **Consistent Feeding Schedule:** Feed at the same times every day. This helps regulate gut motility.
2. **High-Quality Growth Diet:** Choose a diet that meets WSAVA guidelines. This means it is formulated by a qualified nutritionist and undergoes rigorous quality control.
3. **Avoid Table Scraps:** Human food, especially fatty or spicy food, is a major trigger for pancreatitis and gastroenteritis.
4. **Manage Stress:** Australian Shepherds need mental and physical stimulation. A bored or stressed Aussie is more likely to develop stress-related colitis. Ensure they get adequate exercise and mental enrichment.
5. **Regular Veterinary Check-ups:** Annual exams and fecal tests are crucial for early detection of problems.
## Prognosis and Long-Term Management
The prognosis for an Australian Shepherd with a sensitive stomach is generally excellent if the underlying cause is identified. Food allergies and intolerances are managed successfully with dietary changes. IBD can be more challenging but is often controllable with a combination of diet, medication, and supplements.
Owners should expect to be diligent about reading ingredient labels for the life of the dog. It is also important to communicate with anyone who cares for your dog (pet sitters, groomers) about their dietary restrictions.
## Limitations and When to Contact a Veterinarian
This article provides breed-level generalities, but it cannot predict your individual dog's needs. The calorie targets are estimates based on standard formulas, but your Australian Shepherd may have a unique metabolism. Breed-level information cannot account for concurrent diseases, medications, or genetic variations like the MDR1 mutation.
**Contact your veterinarian immediately if you observe any of the following:**
- Vomiting that lasts more than 24 hours or occurs multiple times in a single day.
- Diarrhoea that is bloody, black, or tarry.
- Signs of abdominal pain (whining, pacing, refusing to lie down, or a tense abdomen).
- Lethargy or weakness.
- Loss of appetite lasting more than 24 hours.
- Weight loss over a short period.
- Inability to keep water down (risk of dehydration).
These signs could indicate a life-threatening condition like pancreatitis, a foreign body obstruction, or severe gastroenteritis. Do not attempt to treat these conditions at home.
## Frequently Asked Questions
### 1. How many calories should my Australian Shepherd eat per day?
An adult Australian Shepherd typically needs 900 to 1,400 kilocalories per day, depending on age, neuter status, and activity level, but you should adjust based on body condition score.
### 2. What is the best food for an Australian Shepherd with a sensitive stomach?
The best food is a veterinary-prescribed hydrolyzed protein diet or a limited-ingredient diet with a single novel protein source, but you must first confirm the diagnosis with your veterinarian.
### 3. Are Australian Shepherds prone to food allergies?
Australian Shepherds are not uniquely prone to food allergies, but they are a high-energy breed that often presents with gastrointestinal signs, and adverse food reactions are a common cause of these signs.
### 4. Can I feed my Australian Shepherd a grain-free diet?
Grain-free diets are not recommended unless specifically indicated by your veterinarian, as they have been linked to a risk of dilated cardiomyopathy (DCM) in some dogs, and grains are rarely the cause of food allergies.
### 5. How often should I feed my Australian Shepherd puppy?
Feed an Australian Shepherd puppy three to four times a day until six months of age, then transition to two meals per day for the rest of their life.
### 6. Is it safe to give my Australian Shepherd Imodium for diarrhoea?
No, you should never give loperamide (Imodium) to an Australian Shepherd without a negative MDR1 gene test and explicit veterinary approval, as it can cause severe neurological toxicity.
### 7. What human foods are safe for an Australian Shepherd with a sensitive stomach?
Plain boiled chicken (if not allergic), white rice, and plain canned pumpkin are generally safe for short-term use during an acute upset, but they are not nutritionally complete for long-term feeding.
### 8. How do I know if my Australian Shepherd is overweight?
You should be able to feel their ribs easily without a thick layer of fat, and they should have a visible waist when viewed from above; your veterinarian can confirm this with a Body Condition Score (BCS) assessment.
