Cushing’s disease in dogs is also called Iatrogenic Cushing’s syndrome, chronic inflammatory liver disease, and Cushing’s syndrome in dogs. In this article, we will discuss all the aspects of what is Cushing’s disease in dogs in detail along with its symptoms and causes.
What is Cushing’s Disease in Dogs
Cushing’s disease in dogs is caused when the hormone called cortisol is produced in very large amounts. In other words when adrenal glands overproduce cortisol and it started getting stored in the adrenal gland itself.
Adrenal glands are very important in humans, cats, and dogs. They are regulated by the pituitary gland. The pituitary gland is further regulated by the hypothalamus.
There are so many reasons behind the development of this Cushing disease in dogs. It might be due to pituitary tumors, adrenal gland tumors, and adrenal tumors.
1. Common Types of Cushing’s Disease in Dogs
Mostly Iatrogenic Cushing’s disease occurs naturally in dogs and cats. This crushing disease is more often in dogs as compared to cats. The two very common types of Cushing’s disease in dogs are categorized into two types:
- Pituitary-dependent Cushing’s disease
- Adrenal-dependent Cushing disease.
Almost 80 to 85 percent of Cushing’s disease is pituitary-dependent Cushing’s disease. This is triggered when there is the presence of pituitary gland tumors. Almost 15 to 20 percent of the cause of crushing disease is the presence of tumors either in one or both of the adrenal glands.
The pituitary gland is responsible for making a number of hormones, including the ACTH (adrenocorticotropic hormones), this particular hormone passes through the bloodstream and reaches the adrenal glands in return the adrenal glands produce cortisol.
But no need to worry about pituitary tumors. Dogs’ adrenal gland tumors can be identified by blood tests and ACTH stimulation tests. The doctors do various tests to confirm whether it is an adrenal tumor or a pituitary tumor.
After observing the blood clots, testing adrenal low dose, urinary tract infections, presence of excessive cortisol, and other symptoms the doctor starts the treatment of the dog to reduce the severe illness and increased risk.
2. Common Symptoms of Cushing’s Disease in Dogs
Cushing’s disease is diagnosed by follow-up blood tests and physical exams of excess cortisol and by running adrenal function tests along with observing the dog’s symptoms carefully.
- Excessive production of cortisol
- Increase in thirst
- Increased appetite
- Fragile and thin skin
- Loss in hairs
- Reduction in activities
- Abdomen enlargement
Symptoms of Cushing’s disease will keep on increasing and become severe if not treated properly on time. Curing Cushing’s disease is not an easy task, but it can be cured if the owner takes proper care of their pet and help him to regain normal health.
3. Treatment for Cushing’s Disease in Dogs
Dogs with Cushing’s disease need a bit more care than normal dogs. Doctors first go for the hit and try, which means they try different medicines’ reactions on the dog’s body and observe the side effects. Then accordingly they go for prescribing the required drug to the animal.
Although Cushing’s disease does not have any permanent treatment, the situation can be controlled by giving suitable medication to the pet, developed and approved by the FDA. Few medication side effects are also observed in the animals, but they are not life-threatening.
Vetoryl is the only medicine that has the FDA approved among all the medication treatments for both adrenal-dependent and pituitary-dependent Cushing’s diseases in dogs.
Through the surgical method, the adrenal tumors can also be removed – by removing the adrenal gland. Furthermore, practical studies are still in progress for the pituitary gland tumor gland. It is more complicated, compared to adrenal tumor removal.
However, the Vetoryl drug is not for dogs who have these conditions.
-
Having liver or kidney disease
-
Already taking medications for heart-related diseases
-
Which are pregnant
Side Effects
The side effects of this vetoryl drug include:
- vomiting
- loss of appetite
- weakness
- diarrhea
- energy loss
- bloody diarrhea
- adrenal gland destruction
- potassium and sodium imbalance
This is the reason regular follow-up blood tests are preferred by the doctor, to monitor the effect of the drug on the dog’s body.
Check the medication properly before giving any medication to your dog. Animals are more sensitive than home sapiens. It’s the owner’s duty to take care of their dog in the best way possible.
4. How Long Do the Dogs Live with Cushing disease
according to the American Kennel Club dogs with crushing disease live two years after developing this disorder. The survival rate after two years is only 10%. Note that crushing disease is only reported in elder dogs, the younger and newborn puppies are safe from this disorder. The dogs which suffered from this disorder appear very thin and in the end, they lose most of their muscular power.
The owner might also notice the development of lesions on their pet’s body. In some cases in place of muscle weakness obesity is observed. A special diet is recorded for such dogs which fulfill the requirement of vitamins, minerals, and proteins in dogs’ bodies. Hill’s science diet for adult perfect weight is prescribed by the doctors.
5. Dog Breeds who are Prone to Cushing Disease
Some breeds of dogs are prone to this particular disorder. These breeds include Poodles, Boxers, Boston Terriers, and Yorkshire Terriers. They are required to follow the regular checkup and ensure that their dogs are safe from Cushing disease.
6. Behaviour of Dogs Suffering from Cushing Disease
The dogs who have Cushing disease are very aggressive, have exercise intolerance, face difficulty in moving in there day to day routine, increased pursuit of water and food. They also find it difficult to move upstairs and onto escalators. If these behavioral changes are noticed in your dog then take your dog for a quick checkup.
Final Note
The condition in which the adrenal gland starts producing the excessive amount of cortisol required in the body which ultimately causes the accumulation of cortisol on the adrenal gland is known as Cushing disease. Ensure to keep your dog safe from these conditions.
