I explained to you that traditional Cushing’s disease is due to persistently high body cortisol hormone levels. Austria reported that dogs with Cushing’s disease did, in fact, have elevated levels of cortisol in their hair coat. Cushing’s syndrome (CS) is a disorder of the endocrine system, or a hormonal disorder, that causes high levels of cortisol to appear in the blood. In a normal healthy dog, ACTH (adrenocorticotrophic hormone) is produced by the pituitary gland which is located in the brain. No one patient displays all the signs or symptoms that are apparent in Cushing’s syndrome.
The basic facts gathered from this report are that CS usually occurs in middle-aged to elderly dogs, and that it happens when problems occur with the adrenal or pituitary glands.
The Material contained herein may not be reproduced without the prior written approval of the author. Cushing's disease is common in older dogs, but both diagnosis and treatment can be complicated. Also known as hyperadrenocorticism, Cushing’s is the opposite of Addison's disease (see Addison's Disease: The Great Pretender in last months WDJ). Girl, a Miniature Schnauzer, has lived with Cindy Bright of Indiana, Pennsylvania, since her first owner passed away in 2006. In Springfield, Vermont, Kathy Mason’s beagle, Chance, was diagnosed with PDH at 8 years old.
Most dogs with pituitary tumors are treated with medication because their tumors are considered inoperable. Update: I heard from one person whose 12-year-old dog was treated with radiation therapy for a pituitary tumor.
In Toledo, Ohio, Linda Boyle’s Springer Spaniel, Cody, was diagnosed with Cushing’s disease at age 11 in 2005 after developing a suddenly ravenous appetite and gaining weight. Because Cushing’s patients tend to have high blood pressure and poor healing ability, several months of medical therapy may be needed to strengthen the patient prior to surgery. As this article goes to press, Maggie’s Cushing's symptoms have returned, caused by a new tumor on her remaining adrenal gland.
Cushing’s disease is associated with bladder, skin, and other infections due to the immunosuppressive effects of cortisol. Confirming the diagnosis can be challenging, especially as false positives are common in dogs with nonadrenal illness. Low Dose Dexamethasone Suppression (LDDS), considered the most accurate for diagnosing Cushing’s, takes eight hours in the hospital. Classifying the type of Cushing’s disease as pituitary or adrenal helps determine which treatment is best. Two normal or large adrenal glands indicate the pituitary form of Cushing’s, although enlarged adrenal glands are also often seen in cases of nonadrenal disease due to the chronic stress of the illness.
A study published in 2012 found that giving insulin to dogs with Cushing's who also have elevated glucose levels can prevent the development of diabetes. The best treatment for Cushing’s disease depends on the severity of symptoms, type of Cushing’s, risk of adverse effects, and cost factors. If the dog suffers from a concurrent medical condition, it is important to treat and stabilize that illness if possible before treating for Cushing’s. During the induction phase, caregivers should notify their veterinarians as soon as their dog experiences any appetite reduction, decrease in water consumption, diarrhea, vomiting, lethargy, or listlessness.
If vomiting, diarrhea, appetite loss, or listlessness occur at any time during treatment, the dog may need a prednisone “antidote” pill, which should produce improvement within 30 minutes to two hours. Marked improvement should be seen within six to eight weeks of starting the maintenance dose, with a full reversal of clinical signs after four to six months of treatment. Mitotane can be used to treat adrenal Cushing’s, but a higher dosage is needed, resulting in more adverse reactions.
A study published in 2011 entitled Low-Dose, Twice-Daily Trilostane Treatment for Dogs with Hyperadrenocorticism found that giving smaller doses of Trilostane twice a day worked equally well while causing fewer side effects. A later study, A comparison of once and twice daily administration of trilostane to dogs with hyperadrenocorticism., found that twice-daily administration of trilostane achieved a faster and more effective control for comparable daily doses. Because this drug can block aldosterone as well as cortisol in some dogs, it carries increased risk of side effects such as dehydration, weakness, and electrolyte changes (low sodium and high potassium). For reasons that are not understood, trilostane occasionally causes acute adrenal gland necrosis, which can occur within days of starting the drug or after several months.
A study published in 2012 found that larger dogs may need less trilostane for their weight in order to control Cushing's disease. Most dogs show decreases in drinking, urination, and appetite within one week, but some may take two months or longer.
Trilostane seems to predispose dogs to increased adrenal toxicity from mitotane, so it’s best to wait at least a month in between if switching to mitotane.
L-Deprenyl works by inhibiting ACTH secretion via high dopamine levels in the intermediate pituitary area, where 30 percent of pituitary tumors are located, and may work only for dogs with such tumors. Anipryl is not recommended for dogs who also have diabetes, pancreatitis, heart failure, renal disease, or any other serious illness. A very small percentage of Cushing’s cases result from medical treatments for other conditions, such as the use of prednisone or other corticosteroid medications to control allergies, arthritis, or autoimmune conditions. Pseudo-Cushing's is seen in young dogs (ages 1 to 5) with plush coats, such as Pomeranians, Poodles, Samoyeds, Alaskan Malamutes, and Siberian Huskies. Dogs with this disorder may respond to castration, methyltestosterone, melatonin, growth hormone supplementation, or one of the drugs used to treat Cushing’s disease. Because the diagnosis and treatment of Cushing’s disease can be confusing, expensive, and fraught with adverse side effects, many caregivers turn to alternative or complementary therapies.
For those who prefer treatments that have been proven in double-blind, placebo-controlled clinical trials, unconventional therapies are themselves fraught with peril. At the same time, the cost of veterinary tests, surgery, or prescription drugs for a dog are sometimes simply prohibitive. Elizabeth Knight, of Portland, Oregon, had some success using PS to treat her Welsh Corgi, Jasper, who was diagnosed with Cushing’s at age 11 and lived for two more years. In their book Herbs for Pets, Greg Tilford and Mary Wulff recommend herbal therapy to support organs and systems that are subjected to additional stress because of the disease. Susannah Blanchard of Wilmington, North Carolina, turned to holistic treatments when her 10-year-old Shih Tzu, Bandit, was diagnosed with pituitary-based Cushing’s. Diets for dogs with Cushing’s disease should be high in protein, which can help to combat muscle wasting as well as being good for the skin and immune system.
There is a lot of outdated information on the web about Cushing’s dogs needing a low-fiber, low-purine diet. Dogs with Cushing’s are predisposed to the development of calcium oxalate bladder stones, due to elevated calcium in their urine. It is not unusual for dogs with Cushing’s disease to graduate from holistic therapies to conventional treatments or to take both at the same time. What if your dog has all of the symptoms of Cushing’s – excessive drinking, urination, and appetite, pot belly, skin problems, elevated alkaline phosphatase, etc.
Both forms cause the usual clinical signs of Cushing’s disease, including bloodwork changes and haircoat problems.


According to “Treatment Option Considerations” for atypical Cushing’s on the University of Tennessee’s web site, melatonin may be used as an initial treatment, particularly when alopecia (hair loss) is present. Lysodren (mitotane) can be combined with melatonin and lignans to help lower sex steroid levels other than estradiol, along with suppressive effect on cortisol level. Caroline Levin, a registered nurse who has been researching SARDS in dogs for years, has a different name for atypical Cushing's.
Even slightly elevated estrogen in combination with symptoms such as lethargy, confusion, panting, excessive appetite, and incontinence is significant, according to Levin.
Most dogs with adrenal exhaustion show low cortisol levels, though they may rise to the challenge of an ACTH stimulation test.
Dogs with severe IgA deficiency (IgA < 60 mg) may be unable to absorb oral corticosteroids and other medications, and may require repeated injections of Dexamethasone and Vetalog at 2 to 3 week intervals instead. With appropriate treatment, improvement in mood and energy level may be seen within two to four weeks, but it can take three to nine months before other signs, such as elevated sex hormones, obesity, heat intolerance, and coat changes to improve. While these theories are considered controversial and are not accepted by most conventional veterinarians, many dogs do well with the unconventional approach, especially those with SARDS. I've heard that Vetoryl (Trilostane) may be prohibitively expensive, especially for larger dogs. Cushing's Disease in Dogs: Recommended Diagnostic Protocols and Treatment Options by Mark E. Evaluation of twice-daily lower-dose trilostane treatment administered orally in dogs with naturally occurring hyperadrenocorticism. You can contact me if you have any comments, but I regret to say that I can no longer respond to questions about individual dogs.
These descriptions belong to the dogs in the header and other tooltips, but are displayed here because you have javascript turned off.
One dog may have several of the symptoms, while another dog may also have several, but completely different ones than the other dog. However, some dogs simply cannot afford to stop steroid use due to severe allergies or other serious conditions.
It is also imperative that owners recognize obvious and subtle changes in the physical appearance or behavior of their dogs. Both illnesses involve the adrenal glands, which produce cortisol – a stress hormone that helps prepare a dog for fight or flight by breaking down muscle and fat to convert into glucose. The majority (about 85 percent) of Cushing’s disease cases are caused by tumors of the pituitary gland; these are usually benign (adenomas). The average age at diagnosis with PDH is 10 years, and the most commonly affected breeds are Poodles, Dachshunds, Beagles, German Shepherds, Boxers, Boston Terriers, Labrador Retrievers, and terriers, with 75 percent of patients weighing less than 44 pounds. The average age for diagnosis with adrenal tumors is 11 years, with Poodles, German Shepherds, Dachshunds, Labrador Retrievers, and terriers predominating. She was diagnosed with PDH and began taking Vetoryl (trilostane), a drug that was not approved in the U.S. He was originally treated with Anipryl, which was not effective, and then switched to Lysodren (mitotane).
However, a new surgical technique allows some tumors to be removed (see New Treatment for Pituitary-Dependent Cushing’s Disease, WDJ March 2011. After surgery, prednisone or other corticosteroids may be required for a few months until the dog’s ability to produce cortisol recovers, and some dogs may need mineralocorticoid replacement as well. A negative result rules out Cushing’s, but anything that increases stress can cause a positive result, so further testing is required if the result is positive.
This test is more specific than LDDS, however, meaning that strongly positive results definitely indicate Cushing’s disease, and false positives are unusual, but false negatives are common, particularly when the cause is an adrenal tumor.
A dog with at least three of the typical signs plus a positive test is considered to have Cushing’s, but a dog with no signs but maybe high ALP and a positive test may not, in which case it’s best to take a wait-and-see approach. The endogenous ACTH level is felt by many to be the most accurate method of identifying the type of Cushing’s, but this test is difficult to run, as serum must remain frozen during transport to the lab. Treatment for dogs with concurrent nonadrenal illness, such as diabetes, is complex and beyond the scope of this article. When this happens, mitotane is discontinued and the dog is treated with prednisone until the adrenal glands recover. It is important to stop the medication if this occurs, and some dogs may need fluid support. Trilostane controls clinical signs in dogs with adrenal tumors, but will not slow tumor growth. This antifungal medication suppresses adrenal hormones in about 80 percent of dogs as a side effect. It is not possible to induce Addison’s disease with ketoconazole, so monitoring tests aren’t needed, other than after a month or so to determine if the medication is working.
This drug may reduce clinical signs in up to 30 percent of dogs with adrenal tumors, but side effects are common. It is identified by symmetrical alopecia (hair loss) on the trunk of the body, thighs, or neck, along with darkening of the skin where hair is lost. Because drugs can only relieve symptoms and cannot cure Cushing’s disease or slow its progression, there is little harm in trying alternatives if your dog’s quality of life is not impacted. The company that makes it is NHV Natural Pet Products, and veterinarians at the University of Tennessee College of Veterinary Medicine are using their products with some success. Medical herbalist Hilary Self, the director of Hilton Herbs, created the formula nine years ago for dogs with Cushing’s caused by adrenal adenoma. Fat should be moderately low, as Cushing’s predisposes dogs to hyperlipidemia (elevated cholesterol and triglycerides) and pancreatitis. They found that many dogs have elevated steroid intermediates (also called steroid precursors or “sex steroids”) with normal cortisol. In dogs with hyperestrinism, ACTH stimulation and LDDS tests are usually normal for cortisol, thyroid function is normal or controlled, and liver problems are frequent and typical (very high alkaline phosphatase, enlarged liver, and other liver abnormalities).
This is given even to dogs whose thyroid levels are in the low-normal range (T4 less than 2.0). Other signs, especially food-seeking behavior, may persist even with treatment, especially in dogs that have been subject to elevated estrogen levels for a long time. Some dogs may do well with the more conventional treatment, particularly if an adrenal or pituitary tumor is the underlying cause, or when estrogen is not elevated and SARDS is not a factor.
The condition was first discovered in 1932 by an American surgeon and endocrinologist named Harvey Cushing (1869-1939). The veterinarian then has the challenge of testing doses of treatment medications along with adjusting the steroid prescription. When given in the minimum amount for the weight of the dog twice a day or once every 18 hours it reduces the amount of cortisol in the blood without destroying the gland that produces it. While Addison’s disease results from insufficient cortisol, Cushing’s disease results from too much – and prolonged exposure to cortisol can have negative effects on the entire body.
About 15 percent of Cushings cases are caused by tumors of the adrenal gland, half of which are benign and half malignant (carcinomas).
About half of all cases occur in dogs weighing more than 44 pounds, and females may be more commonly affected. Most dogs are diagnosed with Cushing’s at least six months before neurological symptoms develop.


Another option for large pituitary tumors is radiation therapy, which is expensive ($3,000 to $5,000 in the Los Angeles area) and can have adverse side effects such as skin and hair loss, hearing loss, or problems with tear production in the eyes. It does not indicate liver disease if other liver enzymes such as ALT (alanine aminotransferase) are normal. This test is useful for monitoring treatment, and it is the only test that can be used for dogs currently taking corticosteroids.
If signs are present but test results are negative, consider retesting in three to six months or test for atypical Cushing’s (see Atypical Cushing's below). Dogs with pituitary tumors have high ACTH levels, while those with adrenal tumors will have low or no measurable ACTH. Dogs with a pituitary tumor will show suppression in circulating cortisol levels 75 percent of the time, but those with adrenal tumors never show suppression.
Two-thirds of dogs with tumors greater than 10 millimeters initially will develop neurological signs and may benefit from immediate radiation therapy, even before signs are seen.
See Low dose of insulin detemir controls glycaemia, insulinemia and prevents diabetes mellitus progression in the dog with pituitary-dependent hyperadrenocorticism.
It is not likely to prolong life but does improve the dog’s quality of life, and sometimes the owner’s as well, such as when excessive drinking leads to incontinence and accidents in the house. Mitotane should not be used for dogs who don’t have a good appetite; a poor appetite indicates that something else is going on that must be diagnosed and addressed prior to beginning Cushing’s therapy.
It requires prompt treatment with fluid therapy, glucocorticoids, and mineralocorticoids or it can be fatal (Addisonian crisis). In these cases, the Cushing's is treated by gradual discontinuation of the corticosteroid drugs (if the drugs are withdrawn too quickly, an Addisonian crisis can result).
The newer fourth edition (Hand, et al, 2000), however, has no reference to purines, nor does it make any sense to restrict purines for dogs with Cushing’s. Feeding a low-oxalate diet with other modifications, such as avoiding vitamin C, might be helpful (see Calcium Oxalate Kidney and Bladder Stones, WDJ May 2010). They call this condition “atypical Cushing’s disease,” or “adrenal hyperplasia-like syndrome.”  It has been suggested that cases of atypical Cushing’s disease may be caused by a problem in the steroid production pathway.
Steroid hormone profiling is indicated when other tests of adrenal function are negative (ACTH Stimulation and LDDS), but the dog still exhibits signs of Cushing’s. Symptoms frequently include excessive drinking and urination, along with haircoat problems. Their recommended melatonin dosage is 3 mg twice a day for dogs weighing less than 30 lbs, and 6 mg twice a day for dogs over 30 lbs. The University of Tennessee’s suggested lignan dosage is 10 to 40 milligrams daily of flax hull (SDG) lignan or HRM lignan for small to large dogs. Lysodren may be preferred for treatment of atypical Cushing’s, as Trilostane treatment frequently results in increased estadiol and other intermediate hormone levels. If anyone tries it, I would appreciate it if you would let me know how it works for your dog.
David Bruyette talks about three new medications that may be used to treat pituitary-dependent Cushing's disease in dogs.
The first study was done at UC Davis but lots of dogs died because the dosage was too high.
Cushing’s disease puts dogs at increased risk for diabetes, pancreatitis, calcium oxalate bladder stones, pulmonary thromboembolism, hypertension (high blood pressure), urinary tract infections, protein-losing kidney disease, skin problems, and congestive heart failure.
Adrenal tumors are more common in large-breed dogs, occurring in up to half of dogs with Cushing's (see Cushing's Disease: Overview).
Breeds with short noses, such as Boxers and Pugs, tend to have the largest pituitary tumors. Although successful in 70 percent of cases, further treatment for Cushing’s is usually required, and tumors treated with radiation are likely to recur. An increase greater than four times the normal level suggests Cushing's disease, cholestasis (impaired bile flow), or chronic stress.
Blood samples are sometimes checked after four hours, as this can help classify the form of Cushing’s. Induction time is variable, usually between 7 and 14 days, but some patients require just two to three days and others can take as long as six weeks, especially if they are taking other drugs that interact with Lydsodren, such as phenobarbital or insulin. Baseline cortisol levels measured 4 to 6 hours after trilostane administration may provide adequate monitoring without the need for ACTH stimulation tests. We moved around some, and every new vet who saw Bandit was amazed that he had a Cushing’s diagnosis. It has enabled many owners to either delay having to use the conventional drugs or even reduce a drug’s dosage over a period of months if the dog is already on it. It helps normalize adrenal function, making it appropriate for dogs with both Cushing’s and Addison’s disease. Keeping your dog well hydrated and allowing frequent urination can also help prevent stone formation. Elevated steroid intermediates have been linked to sudden acquired retinal degeneration syndrome (SARDS), which causes sudden blindness in dogs. Dogs with the adrenal form will also have an enlarged liver and elevated liver enzymes, but in this case only one adrenal gland will be enlarged (the other may be atrophied), and endogenous ACTH levels will be decreased. Who knows what’s in those pills and whether or not they actually work, but the ads should make it clear that stress can be a number of things.
About 95 percent of dogs with Cushing’s test positive, but false positives are also common, and the more severe a nonadrenal illness, the more likely a false positive result. This may be the preferred test if symptoms are mild, for it is better to miss the diagnosis than get a false positive. This test may also be more accurate for diagnosing dogs who are already diabetic.
See Updates at right that support starting with a lower initial dosage, particularly for larger dogs. I credit the Cushex for keeping his coat rather thick with none of the thinning that generally accompanies Cushing’s disease. I was initially terrified of Cushing’s, but I now understand it and have respect for the treatments that are available. See my older article, New Treatment for Pituitary-Dependent Cushing's Disease, for more info from and about Dr. Although Cushing's sometimes causes weight gain, it is causing Chakka to lose weight and he is nothing but skin and bones. Without it she would die an early death due to the havoc excess cortisol wreaks on the body. He will eat his own poop or the poop of the other dogs in the house if the poop isn't immediately picked up. Not sure if it was the Cushing's that caused his teeth to rot, but his teeth either fell out or were pulled out by the vet.
