Cushing’s disease—also known as hyperadrenocorticism—is a complex hormonal disorder that affects thousands of dogs each year, particularly as they age. It occurs when a dog’s body produces excessive amounts of cortisol, a hormone that regulates stress, metabolism, immune response, and more. Left unmanaged, Cushing’s can lead to serious health complications including diabetes, hypertension, urinary tract infections, skin thinning, and muscle wasting. While medication and veterinary care are essential components of treatment, nutrition plays a pivotal role in managing symptoms and improving quality of life.

What to Look for When Buying Buying Guide
1. High-Quality, Easily Digestible Protein
Protein is the cornerstone of any dog’s diet, but for dogs with Cushing’s disease, the source and quality of protein become even more critical. Excess cortisol breaks down muscle tissue, leading to muscle wasting and weakness. Therefore, dogs with Cushing’s need a diet rich in high-quality, bioavailable protein to help maintain lean muscle mass and support metabolic function.
Look for canned dog foods that list a named animal protein as the first ingredient—such as chicken, turkey, lamb, or salmon. Avoid vague terms like “meat meal” or “animal by-product meal,” which can include lower-quality or inconsistent protein sources. Ideally, the protein should be cooked gently to preserve amino acid integrity and be easily digestible to reduce strain on the digestive system.
Additionally, consider the protein-to-fat ratio. While protein is essential, excessive fat can contribute to pancreatitis—a risk for dogs with Cushing’s. Aim for a balanced formulation where protein makes up 25–35% of the dry matter content, depending on your dog’s activity level and overall health.
2. Controlled Fat Content
Fat provides energy and supports skin and coat health, but dogs with Cushing’s are at higher risk for pancreatitis and obesity due to cortisol’s impact on metabolism. Therefore, fat content in canned dog food should be carefully managed—not too low, but certainly not excessive.
Ideal fat levels for dogs with Cushing’s typically range from 10% to 15% on a dry matter basis. This provides enough energy without overloading the pancreas or contributing to weight gain. Look for foods that use healthy fat sources like chicken fat, flaxseed oil, or fish oil, which also supply omega-3 fatty acids beneficial for reducing inflammation.
Avoid foods with high-fat ingredients such as beef tallow, pork fat, or excessive amounts of oil. Also, be cautious of “grain-free” formulas that compensate for lower carbohydrates with added fats—these can be problematic for Cushing’s dogs.
Remember, fat is calorie-dense. Even if your dog isn’t visibly overweight, excess calories can exacerbate insulin resistance and complicate diabetes management, which is common in Cushing’s patients.
3. Moderate to High Fiber for Digestive and Blood Sugar Support
Fiber plays a dual role in managing Cushing’s disease: it supports healthy digestion and helps regulate blood sugar levels. Dogs with Cushing’s often experience polyuria (excessive urination) and polydipsia (excessive thirst), and some develop insulin resistance or diabetes mellitus. Soluble fiber, in particular, slows glucose absorption and promotes satiety, which can help stabilize energy levels and reduce hunger spikes.
Look for canned foods that include moderate to high levels of dietary fiber—ideally between 4% and 8% on a dry matter basis. Good sources include pumpkin, sweet potato, peas, beet pulp, and chicory root. These ingredients also support gut microbiome health, which is increasingly recognized as important for immune function and inflammation control.
Insoluble fiber, such as cellulose, can also aid in maintaining regular bowel movements, which is helpful for dogs who may experience constipation due to medication side effects or reduced activity.
Be cautious with extremely high-fiber diets, as they can interfere with the absorption of certain minerals and medications. Always consult your veterinarian before making significant dietary changes, especially if your dog is on trilostane or mitotane.
4. Low to Moderate Sodium Levels
Hypertension (high blood pressure) is a common complication of Cushing’s disease, affecting up to 80% of diagnosed dogs. Excess sodium in the diet can worsen hypertension by increasing fluid retention and putting additional strain on the heart and kidneys.
When selecting canned dog food, check the sodium content—ideally, it should be less than 0.3% on a dry matter basis. Many commercial dog foods, especially those with added flavor enhancers or preservatives, contain significantly higher levels of sodium. Canned foods are often higher in moisture, which can dilute sodium concentration, but it’s still important to read labels carefully.
Avoid foods with added salt, sodium nitrate, or other sodium-based preservatives. Instead, opt for brands that use natural preservation methods like mixed tocopherols (vitamin E) or rosemary extract.
If your dog has been diagnosed with hypertension, your vet may recommend a therapeutic low-sodium diet. In such cases, prescription diets like Hill’s Prescription Diet h/d or Royal Canin Cardiac may be appropriate, though they are typically dry kibble. However, some brands offer low-sodium canned options that can be used in rotation or as toppers.
5. Limited Ingredient and Hypoallergenic Formulas
Dogs with Cushing’s often have compromised immune systems and are more prone to skin infections, allergies, and food sensitivities. Cortisol suppresses immune function, making it harder for the body to fight off pathogens and increasing the risk of inflammatory responses.
Choosing a limited ingredient diet (LID) can help reduce the likelihood of triggering allergic reactions or digestive upset. These formulas typically contain one protein source and one carbohydrate source, minimizing the number of potential allergens.
Hypoallergenic or novel protein options—such as duck, venison, or rabbit—can be especially beneficial if your dog has shown signs of food intolerance. Similarly, novel carbohydrates like sweet potato or chickpeas may be easier to digest than common grains like corn or wheat.
While grain-free diets were once trendy, recent studies have raised concerns about their potential link to dilated cardiomyopathy (DCM) in dogs. Unless your dog has a confirmed grain allergy, it’s generally safer to choose formulas that include whole grains like oats, barley, or brown rice, which also provide fiber and nutrients.
Always introduce new foods gradually over 7–10 days to monitor for adverse reactions such as vomiting, diarrhea, or itching.
6. Added Supplements for Immune and Joint Support
Cushing’s disease accelerates the aging process and can lead to joint stiffness, reduced mobility, and chronic inflammation. Therefore, canned dog foods enriched with specific supplements can provide targeted support for overall health and comfort.
Look for formulas that include glucosamine and chondroitin for joint health, especially if your dog is older or shows signs of arthritis. Omega-3 fatty acids (EPA and DHA) from fish oil are also essential for reducing inflammation and supporting skin, coat, and brain health.
Antioxidants like vitamin E, vitamin C, and selenium help combat oxidative stress caused by excess cortisol. Probiotics can support gut health, which is linked to immune function and nutrient absorption. Some premium brands also include adaptogens like ashwagandha or turmeric, though evidence for their efficacy in dogs is still emerging.
While supplements can be beneficial, avoid over-supplementation. More is not always better—excess vitamins or minerals can be harmful. Stick to balanced, complete-and-balanced diets that meet AAFCO (Association of American Feed Control Officials) standards.
7. Palatability and Moisture Content
Dogs with Cushing’s often experience changes in appetite. Some may eat ravenously due to increased hunger, while others may lose interest in food because of nausea, medication side effects, or fatigue. Canned dog food’s high moisture content—typically 70–80%—can make it more appealing and easier to eat, especially for senior dogs or those with dental issues.
Palatability is crucial for ensuring your dog consumes enough calories and nutrients. Look for foods with natural flavor enhancers like real broth, liver, or meat juices. Avoid artificial flavors, colors, or sweeteners, which offer no nutritional value and may cause digestive upset.
The texture of canned food can also matter. Some dogs prefer pâté-style formulas, while others enjoy chunks in gravy or shredded meat. If your dog is picky, consider rotating between a few high-quality brands to keep meals interesting.
Additionally, the high water content in canned food can help support kidney function and reduce the risk of urinary tract infections—common in dogs with Cushing’s due to frequent urination.
8. Brand Transparency and Quality Control
Not all pet food brands are created equal. When managing a chronic condition like Cushing’s, it’s essential to choose a manufacturer with a strong reputation for quality, safety, and transparency.
Look for brands that provide detailed ingredient sourcing information, conduct regular third-party testing, and have a clear recall history. Companies that manufacture their own food (rather than relying on co-packers) often have tighter quality control.
Check whether the brand follows AAFCO guidelines and whether their foods are formulated by veterinary nutritionists. Some of the most trusted brands in the industry—such as Hill’s Science Diet, Royal Canin, Purina Pro Plan, and Wellness—have veterinary nutrition teams and publish peer-reviewed research.
Avoid brands with vague labeling, frequent recalls, or a history of contamination. Reading customer reviews and consulting with your veterinarian can also help you identify reliable options.
Finally, consider whether the brand offers a satisfaction guarantee or return policy. This can provide peace of mind when trying a new food for your dog.
Different Types of Buying Guide
Common Buying Mistakes to Avoid
❌ Mistake: Choosing Based on Marketing Claims Alone
Why it’s bad: Many pet food brands use buzzwords like “natural,” “holistic,” or “premium” without clear definitions or regulatory oversight. These terms can be misleading and don’t guarantee nutritional adequacy or suitability for dogs with Cushing’s.
What to do instead: Focus on the ingredient list and guaranteed analysis. Look for AAFCO statements that confirm the food is complete and balanced for your dog’s life stage. Consult your vet or a veterinary nutritionist if you’re unsure.
❌ Mistake: Ignoring Sodium Content
Why it’s bad: High sodium intake can worsen hypertension, a common complication of Cushing’s. Many canned foods contain added salt for flavor, which can be dangerous for dogs with high blood pressure.
What to do instead: Check the sodium percentage on the label and aim for less than 0.3% on a dry matter basis. Use a dry matter calculator if needed, and consider low-sodium prescription options if recommended by your vet.
❌ Mistake: Overlooking Protein Quality
Why it’s bad: Low-quality or plant-based proteins (like corn gluten meal or soy) are less bioavailable and may not support muscle maintenance in dogs with Cushing’s. Excess plant protein can also strain the kidneys.
What to do instead: Prioritize named animal proteins as the first ingredient. Avoid foods where plant proteins dominate the top of the list.
❌ Mistake: Switching Foods Too Quickly
Why it’s bad: Sudden dietary changes can cause gastrointestinal upset, especially in dogs with sensitive systems or those on medication. This can lead to refusal to eat, which is dangerous for dogs with chronic illness.
What to do instead: Transition to new food gradually over 7–10 days, mixing increasing amounts of the new food with the old. Monitor for signs of digestive distress.
❌ Mistake: Neglecting Moisture Needs
Why it’s bad: Dogs with Cushing’s drink and urinate frequently, increasing their risk of dehydration. Dry kibble alone may not provide enough hydration.
What to do instead: Incorporate canned food or add water/broth to kibble to boost moisture intake. This supports kidney function and reduces UTI risk.
❌ Mistake: Not Consulting a Veterinarian
Why it’s bad: Every dog with Cushing’s is different. What works for one may not suit another, especially if there are comorbidities like diabetes or kidney disease.
What to do instead: Always involve your vet in dietary decisions. They can recommend specific formulations, monitor lab work, and adjust treatment as needed.
Budget Guidelines: How Much Should You Spend?
When managing a chronic condition like Cushing’s, it’s natural to want the best for your dog—but that doesn’t always mean the most expensive option. Here’s a breakdown of what to expect at different price points:
Entry-Level ($1.00–$1.80 per can): These foods are often available at big-box stores or supermarkets. While convenient, they may contain lower-quality proteins, fillers, and higher sodium levels. Some budget brands have improved in recent years, but careful label reading is essential. Look for options with real meat as the first ingredient and avoid those with excessive by-products or artificial additives.
Mid-Range ($1.80–$2.80 per can): This is the sweet spot for most dog owners. Brands in this range—such as Purina Pro Plan, Blue Buffalo, and Nutro—offer balanced nutrition, quality ingredients, and added supplements. Many include probiotics, omega-3s, and moderate fiber levels. These foods are widely available and often recommended by veterinarians for general health maintenance.
Premium ($2.80–$3.80 per can): Premium brands like Wellness, Merrick, and Taste of the Wild focus on high-quality, minimally processed ingredients. They often use novel proteins, limited grains, and natural preservatives. These foods are ideal for dogs with sensitivities or those needing extra nutritional support. While more expensive, they can reduce the need for supplements and improve overall health outcomes.
Luxury ($3.80+ per can): At the top end, you’ll find boutique brands, fresh-cooked options, and veterinary therapeutic diets. These are often formulated by veterinary nutritionists and may include functional ingredients like adaptogens or medicinal mushrooms. While not necessary for all dogs, they can be beneficial for those with complex health needs or poor response to standard treatments.
