Symptoms of Addison�s disease are not so specific in dogs. Moreover, even these vague symptoms vary over a period leading to a situation where dog owners are not even sure of its prevalence. Addison�s disease generally occurs due to autoimmune conditions.

Although it is not a conclusive diagnostic procedure, it is important to look for the level of primary ions of electrolytes like sodium and potassium. The proper amount and distribution of electrolytes in the body is essential for your dog�s health.

Final diagnosis of Addison�s disease, however, is done only after checking the response of the dog�s body to ACTH. ACTH is a hormone that is secreted by the anterior pituitary gland to stimulate the adrenal cortex to produce its own hormones.

Addison�s disease is basically a production disorder and is caused by an insufficiency of hormones secreted by the adrenal cortex. This is unlike canine Cushing�s disease, which is caused by excessive production of adrenal hormones. Addison�s disease is managed by giving supplemental hormones.

Aldosterone, a corticosteroid hormone produced by the adrenal glands that regulates salt (sodium and potassium) and water balance needs to be supplemented. This is achieved by administering a mineralocorticoid that influences the metabolism of sodium and potassium.

Cushings disease is a serious condition that develops in middle aged and older dogs. Since the basic cause of the condition is excess production of cortisol by the adrenal glands, it is also known as hyperadrenocorticism.

Cortisol is a stress hormone that is produced by the adrenal cortex on signals received through ACTH (adrenocorticotrophic hormone). Cortisol plays an important role in metabolism and higher than required levels in the body can lead to symptoms like hair loss, muscle weakness, dry and brittle skin, pot belly and a significant increase in thirst and urination.

Although holistic treatment has been associated mainly with alternative therapies, medical science has slowly started accepting the philosophy of medical care. Holistic health care is not a method of treatment but an approach to how to go about treating disease. Holistic treatments consider that all aspects of life are closely interconnected. Symptoms are simply the body�s way of showing that it needs attention. Fever, for example, is considered as body�s own effort at fighting infection.

The term ‘organic’ is contextual and has various meanings. For the purpose of this article organic means as much as it relates to bodily organs.

The two major organs involved in the development of Cushing’s syndrome in dogs are the two glandular organs of the endocrine system – the pituitary and the adrenal glands (to be particular, the adrenal cortex). The pituitary is the parent gland that releases Adrenocorticotropin hormone (ACTH) to signal the adrenal cortex to release the stress hormone, cortisol.

Excess of this hormone is the basic cause of Cushing’s syndrome. Excessive levels of cortisol may be caused due to a problem, usually a tumor, with the pituitary or the adrenal gland. When the problem is caused due to a pituitary tumor, it is known as Cushing’s disease.

Regardless of the nature of these tumors, benign or malignant, the result is increase in production of cortisol. Dogs that have previously undergone corticosteroid therapy for allergies or immune diseases are also at a risk of developing symptoms of Cushing’s syndrome.

Cortisol has a strong physiological and chemical effect and acts as an anti-inflammatory and immunosuppressive agent. Large amounts of free circulating cortisol in the body suppress the dog’s immune system, exposing it to various bacterial infections.

Stroke Signs, Symptoms, And Causes Of Strokes In Dogs

Everybody is familiar with the fact that humans have strokes. It is a serious medical issue that people must be aware of when it comes to their own health. However, most of us do not realize that our pets can also suffer a stroke and receive severe brain damage. Experts use to claim that dog strokes were very rare, however during recent MRI scanning documentation, it appears that strokes in dogs is a lot more prevalent than we think.

What Exactly Is A Stroke?

A stroke is caused when the brain becomes suddenly damaged by a lack of blood supply. This could be caused by a blood clot or bleeding to the brain from a ruptured vessel (hemorrhaging). If the bleeding is not stopped as soon as possible, further damage will occur. The extra pressure against the skull from swelling can cause a lot of brain tissue to be destroyed in the process.

What Are The Signs & Symptoms Of Dog Stroke?

Cushing�s disease is common in middle and old aged dogs. It is an endocrine disease that falls under the category of production disorders. Also known as hyperadrenocorticism, it is a condition of excess cortisol in the blood. Cortisol is a steroid hormone that is produced by the adrenal glands during periods of stress. Problems with the adrenal glands or with the controlling gland, the pituitary, can lead to production of cortisol even in the absence of stress.

Canine Cushing�s disease is characterized by symptoms that include excessive drinking, increased urination, distended stomach, thin skin and excessive hair loss. Behavioral symptoms may include reluctance to play and indifference.

Although it is known that adrenal or pituitary tumors cause the adrenal glands to produce more than required cortisol, surgical excision is usually avoided considering the age of the dog and the risks involved. Other factors that restrict dog owners to go for aggressive treatment are the high costs of diagnostic tests and treatment and the side effects of immunosuppressive drugs and drugs that destroy adrenal tissue responsible for production of cortisol.

Cushing�s syndrome is a disorder of the endocrine system caused by excessive secretion of cortisol by the adrenal cortex. The underlying cause can lie with the adrenal glands or the pituitary gland, which controls adrenal secretions with ACTH, a hormone produced by the anterior pituitary gland.

A pituitary adenoma (benign tumor in the gland, also known as Cushing�s disease), adrenal tumor or other conditions that lead to excessive production of ACTH may also lead to a series of symptoms associated with Cushing�s syndrome.

Common symptoms of Cushing�s disease include hair loss, weight loss despite proper diet, lethargy, increased thirst and urination and anemia.

The conventional approach to treating endocrine disorders is to use immunosuppressive drugs or hormonal replacements as the case may be. Conditions caused due to an adrenal tumor may require complete removal of the gland. However, in cases of pituitary tumors it may not be possible to remove this delicate gland.

The disturbing factor associated with conventional treatment is that Cushing�s disease may also occur due to a complication resulting from treatment, especially steroid use. Administration of steroids can lead to the most recognizable symptom, hair loss.

Domestication, an increased focus on dog health and veterinarian medicine has led to a situation where pet dogs live longer. Selective breeding to produce individual dog breeds has also led to certain genetic diseases that were not very common before. The practical consequence of this is that dog owners have to deal will more dog diseases than ever before.

Apart from certain dog specific diseases, dogs suffer from practically all diseases experienced by humans. Like humans, dogs to can develop bacterial, fungal and viral infections, skin, orthopedic and eye diseases and tumors and cancers. To add to it all there are diseases associated with old age too. Cushing�s syndrome is one such disorder that is usually seen in older dogs.

Canine Cushing�s syndrome may be endogenous or exogenous. Endogenous Cushing�s is a condition where either of the two main endocrinal glands, the pituitary or the adrenal gland stimulate or produce excessive cortisol within the body. Cortisol is a stress hormone and elevated levels of the hormone depress immune and inflammatory responses. The primary cause of exogenous Cushing�s is the administration of steroid medication.

Cushing�s disease is a glandular disorder caused by excessive corticosteroids. The process of the production of these corticosteroids is such that:

* The pituitary gland produces a hormone called ACTH
* The ACTH stimulates the adrenalin glands
* The adrenalin gland produces corticosteroids
* A more than required amount of corticosteroid can cause Cushing�s disease, so it is also called hyperadrenocorticism (hyper-adreno-corticism).

The overproduction of corticosteroids which causes Cushing�s disease in dogs can occur due to two types of conditions. In 85% of the cases, the excessive production of ACTH is caused by a tumor in the pituitary gland that produces high levels of ACTH. This causes the adrenalin glands to make more than required levels of corticosteroids. Hyperadrenocorticism in a dog can also be caused by a corticosteroid-producing tumor in one or both of the adrenalin glands.

Cushing�s disease in dogs can also be caused by large doses of synthetic corticosteroids. These steroids may be administered for treating another ailment but in turn produce a side effect that results in Cushing�s disease.

Cushing�s disease generally occurs in dogs that are five years or older. It is more common in female dogs than in male dogs. Some breeds like Terriers, Poodles, and Dachshunds are more prone to Cushing�s disease for some inexplicable reason.

What is Cushing�s Disease?

Cushing’s disease is also known as hyperadrenocorticism and is characterized by the over-production of hormones from the adrenal glands. The extra high levels of these hormones in your pet�s body can cause varied and serious symptoms.

Function and definition of the adrenal glands

The adrenal glands are two, small bean-shaped structures situated above each of your pet�s two kidneys. They consist of two separate regions: an inner adrenal medulla surrounded by an outer adrenal cortex.

The adrenal glands release a wide variety of hormones. The medulla is responsible for producing epinephrine and norepinephrine (adrenaline). These hormones control the body�s reaction to stress and affect blood pressure and heart rate. The adrenal cortex produces hormones such as cortisone and aldosterone which are necessary for balancing fluid and electrolytes (salt) in the body as well as regulating the use of dietary protein, fats and carbohydrates and controlling inflammation.

What are the symptoms of Cushing�s Disease?

High levels of corticosteroids in the body can cause a number of health problems in pets including:

* Increased thirst/drinking and urination
* Increased appetite
* Panting
* High blood pressure
* Loss of hair
* Calcified lumps in the skin
* Thinning skin and susceptibility to infections
