Addison's disease in dogs is a rare disorder caused by insufficient levels of hormones produced by the adrenal glands. It is often hard to diagnose because its symptoms are vague and non-specific, and can come and go for years. While any dog can develop Addison's, certain breeds are predisposed to it, including Great Danes, Nova Scotia Duck Tolling Retrievers, and Portuguese Water Dogs. The disease can be treated with prescription drugs and electrolyte tests, but some dog owners also opt for holistic therapies, which include dietary changes.

Addison's disease in dogs is uncommon, affecting 0.36% to 0.5% of dogs
Addison's disease in dogs, or hypoadrenocorticism, is an uncommon illness, affecting only 0.36% to 0.5% of dogs. It is caused by insufficient levels of hormones produced by the adrenal glands, which can result from the body's immune system attacking the glands, cancer within the glands, infection, or lack of blood supply. The clinical syndrome occurs when at least 85% to 90% of the adrenocortical tissue is destroyed, leading to deficiencies of mineralocorticoids such as aldosterone, and glucocorticoids such as cortisol. Aldosterone plays a vital role in regulating sodium, potassium, and body water balance, while cortisol is often referred to as the 'natural stress hormone' and is important for metabolism and the immune system.
The disease can affect any dog, but certain breeds seem to be at increased risk, including Portuguese Water Dogs, Bearded Collies, Standard Poodles, Nova Scotia Duck Tolling Retrievers, Leonbergers, Great Danes, and Labrador Retrievers. Clinical signs of Addison's disease can be varied and nonspecific, but often include lethargy, diarrhoea, vomiting, increased thirst, increased urination, and unplanned weight loss. Intermittent shaking episodes are also sometimes observed. These signs may come and go, making it challenging to diagnose the disease. To confirm a diagnosis, a vet will perform an ACTH stimulation test, which involves measuring the response of the adrenal glands to a small, harmless hormone injection.
Treatment for Addison's disease typically involves prescription drugs and electrolyte tests, but holistic veterinarians may also recommend various support therapies, including nutritional adjustments. While diet cannot cure Addison's disease, foods made with poor-quality ingredients or diets that lead to nutritional deficiencies can cause additional stress, which is detrimental to dogs with Addison's. Probiotics and digestive enzyme powders can be beneficial additions to a dog's diet, and adrenal cortical extracts, either oral or injected, may also be prescribed. In some cases, lifestyle modifications may also be recommended alongside veterinary treatment.
Although Addison's disease in dogs is uncommon, it can have serious health consequences. Treatment options are available, and most dogs can resume normal lives after an Addisonian crisis. With proper veterinary care and, in some cases, dietary and lifestyle adjustments, dogs with Addison's disease can be effectively managed.

The disease is caused by insufficient hormone production by the adrenal glands
Addison's disease in dogs is a rare disorder caused by insufficient hormone production by the adrenal glands. It is also known as hypoadrenocorticism and can be very frustrating for pet owners and veterinarians due to its varied and vague clinical signs. The disease occurs when there is a deficiency of mineralocorticoids and glucocorticoids, specifically cortisol and aldosterone. Cortisol is often referred to as the "'natural stress hormone'" and plays a crucial role in metabolism and the immune system. Aldosterone is responsible for maintaining the balance of sodium, potassium, and body water.
The adrenal glands are located near the kidneys and are responsible for producing several important hormones. These hormones have various functions, including regulating blood pressure, controlling electrolyte balance, maintaining a healthy intestinal tract, and enabling the body to respond appropriately to stress. When the adrenal glands do not produce enough of these hormones, it can lead to serious health consequences for dogs.
The most common cause of Addison's disease in dogs is an immune-mediated destruction of adrenal tissue, where the body's immune system attacks the glands. Less commonly, the adrenal glands may be damaged by trauma, infection, cancer, or as a result of treating Cushing's disease with certain medications. Secondary Addison's disease can also develop if a dog has been treated with long-term steroids and the medication is abruptly stopped, known as iatrogenic hypoadrenocorticism. This condition is generally temporary.
The clinical signs of Addison's disease can vary and may come and go, making it challenging to diagnose. Some of the most common symptoms include lethargy, diarrhoea, vomiting, increased thirst and urination, unplanned weight loss, and intermittent shaking episodes. In later stages, dogs may experience an Addisonian crisis, characterised by low heart rate, abnormal electrolyte levels, dehydration, and extremely low blood pressure. This is considered a medical emergency requiring immediate veterinary treatment.
Treatment for Addison's disease typically involves prescription drugs, electrolyte tests, and, in some cases, holistic therapies. While diet alone cannot cure the disease, nutritional deficiencies and poor-quality ingredients can be a significant source of stress for dogs with Addison's. Probiotics and digestive enzyme powders can be beneficial additions to a dog's diet, regardless of whether it is home-prepared, raw, cooked, canned, frozen, or packaged. In some cases, veterinarians may prescribe adrenal cortical extracts or supplements like Standard Process Canine Adrenal Support to support adrenal function.

Clinical signs are vague and may include lethargy, diarrhoea, vomiting, and shaking
Addison's disease in dogs, also known as hypoadrenocorticism, is a rare disease that affects the adrenal glands, causing them to produce insufficient amounts of certain hormones. The clinical signs of this disease can be vague and non-specific, making it challenging to diagnose.
One of the most common clinical signs of Addison's disease in dogs is lethargy. Affected dogs may experience increased lethargy, with decreased energy levels and a lack of interest in their surroundings. This can be an early sign of the disease and may come and go, making it difficult for owners to identify.
Another possible clinical sign is diarrhoea. Dogs with Addison's disease may experience gastrointestinal issues, leading to diarrhoea and other digestive problems. This can be intermittent and may be accompanied by a loss of appetite, as some dogs with the disease become picky eaters.
Vomiting is also a potential symptom of Addison's disease. Dogs may experience vomiting episodes, especially during an Addisonian crisis, a severe form of the disease. Vomiting can occur in conjunction with diarrhoea and other symptoms, indicating a more serious case of the disease.
Intermittent shaking episodes are sometimes observed in dogs with Addison's disease. The shaking can be a result of the abnormal stress response caused by the disease. The disease affects the production of cortisol, also known as the "natural stress hormone," leading to an abnormal response to stressful situations.
While there is no special diet that can cure Addison's disease, nutrition plays a crucial role in managing the condition. A balanced diet with high-quality ingredients is essential to avoid nutritional deficiencies that can cause additional stress on the dog's body. Holistic veterinarians often recommend adding probiotics and digestive enzyme powders to support the dog's overall health and digestion.

Treatment includes prescription drugs and electrolyte tests, with diet and activity levels typically unchanged
Addison's disease in dogs, or hypoadrenocorticism, is a rare disease that affects the adrenal glands, causing them to produce insufficient amounts of certain hormones. The most common hormones affected are glucocorticoids and mineralocorticoids, which play important roles in metabolism, the immune system, and the body's response to stress. The disease can be caused by a variety of factors, including autoimmune processes, cancer, infection, or lack of blood supply to the adrenal glands.
Treatment for Addison's disease in dogs typically involves prescription medications and regular electrolyte tests to monitor the dog's condition. The medication used depends on the specific needs of the dog and the severity of the disease. One common medication is desoxycorticosterone pivalate (DOCP), which is injected every 3 to 4 weeks and replaces the missing mineralocorticoid aldosterone. It is often supplemented by an oral glucocorticoid. In some cases, oral medications such as fludrocortisone may be preferred over injections. These medications can help regulate the dog's hormone levels and manage the disease.
It is important to note that while diet and activity levels typically remain unchanged, some veterinarians may recommend lifestyle modifications to optimise the dog's overall health and well-being. Holistic veterinarians may also suggest additional support therapies, including nutritional adjustments, to complement the prescription medications. For example, the addition of probiotics and digestive enzyme powders can improve a dog's diet and aid in digestion. Furthermore, during an Addisonian crisis, when a dog experiences a sudden decline in health, immediate veterinary treatment is required, and dietary adjustments are not the primary concern.
While diet does not typically require significant changes, it is still important to provide a balanced and nutritious diet to support the overall health of dogs with Addison's disease. Poor-quality ingredients or nutritionally deficient diets can cause additional stress, which is detrimental to dogs with this condition. Therefore, veterinarians may recommend high-quality foods or supplements to ensure optimal nutrition.
In summary, the treatment for Addison's disease in dogs primarily involves prescription medications and regular electrolyte tests. While diet and activity levels usually remain unchanged, veterinarians may suggest lifestyle modifications, including nutritional adjustments, to optimise the dog's overall health and manage the disease.

Probiotics and digestive enzymes can improve a dog's diet and help with digestive problems
Dogs with Addison's disease may not need a special diet, and their diet and activity levels can often remain unchanged. However, it is a serious condition that requires the highest value nutrition possible so that the body has the energy to rebalance itself.
Addison's disease, also known as hypoadrenocorticism, is caused by a decreased output of steroid and stress hormones by the adrenal glands. The adrenal glands are responsible for the production of hormones that regulate blood pressure, control the balance of certain electrolytes in the body, and maintain a healthy intestinal tract.
Digestive enzymes, on the other hand, are proteins that help break down food into smaller components that can be easily absorbed by the body. They are produced by the body, but supplemental enzymes can be beneficial in improving digestion and nutrient absorption. Digestive enzymes work alongside probiotics to ensure proper nutrient absorption and support overall digestive health.
Supplementing with probiotics and digestive enzymes can be especially beneficial for dogs with Addison's disease, as they can help improve their digestive health and ensure proper nutrient absorption. Probiotics can help balance the gut flora, reducing the risk of digestive issues that may be caused by the disease or its treatment. Additionally, digestive enzymes can aid in breaking down food, reducing the workload on the digestive system and helping to maximize nutrient absorption.
Some sources recommend a raw food diet for dogs with Addison's disease, as it is more easily digested and absorbed. A raw food diet typically consists of high-protein, low-carbohydrate meals, which can help support lean muscle mass and provide the energy needed for the body to heal. If a raw food diet is not feasible, a cooked, whole food diet is recommended as the next best option.
