Amyloidosis in Dogs: Causes, Symptoms, and Treatment Recognizing and Managing Amyloidosis In Dogs

Amyloidosis in Dogs: Causes, Symptoms, and Treatment

Amyloidosis, which causes organ failure and dysfunction in dogs, is the abnormal buildup of amyloid protein in a variety of tissues and organs throughout the body of the canine. In this article, we explore this condition further.

Amyloidosis is a rare but potentially life-threatening condition that can affect dogs of any breed or age. Amyloid protein abnormally builds up in many tissues and organs throughout the body, which causes organ failure and malfunction. Because the symptoms of this ailment can vary greatly and resemble those of other conditions, diagnosing it can be difficult.

In this article, we'll look at the causes, signs, diagnoses, and available treatments for canine amyloidosis, as well as the value of early discovery and follow-up, to help affected dogs have a better prognosis.

Causes of Amyloidosis

There are several possible causes of amyloidosis in dogs, including:

  • Primary amyloidosis: The ailment is classified as primary amyloidosis when there is no recognized etiology for the amyloidosis in question.

  • Secondary amyloidosis: This kind of amyloidosis results from underlying, protracted inflammatory illnesses such as persistent infections, autoimmune diseases, or certain cancers.

  • Familial amyloidosis: Due to genetic abnormalities that influence the generation or clearance of amyloid protein, certain dog breeds are prone to developing amyloidosis.

  • Age-related amyloidosis: As dogs get older, they may naturally accumulate amyloid protein in various tissues, which can lead to the development of amyloidosis.

  • Drug-induced amyloidosis: The accumulation of amyloid proteins in the kidneys and subsequent development of renal amyloidosis in dogs have been linked to specific treatments, such as prolonged usage of non-steroidal anti-inflammatory drugs (NSAIDs).

The symptoms of canine amyloidosis vary based on the organs and tissues affected by the aberrant amyloid protein buildup. Among the most typical signs are:

  • Weight loss

  • Reduced appetite

  • Weakness or sluggishness

  • Excessive urination or thirst

  • Diarrhea and vomiting

  • Enlarged abdomen

  • Difficulty breathing

  • Skin lesions or rashes

  • Eye abnormalities, such as cloudiness or glaucoma

  • Kidney dysfunction or failure

  • Liver dysfunction or failure

  • Heart abnormalities or failure

Testing for amyloidosis in dogs

There are several diagnostic tests that can be used to diagnose amyloidosis in dogs. These tests may include:

  • Blood and urine tests: Blood and urine tests can help detect abnormalities in organ function and may indicate the presence of amyloidosis. For instance, elevated levels of creatinine or urea in the blood or protein in the urine may be suggestive of hepatic amyloidosis in dogs.

  • Imaging investigations: To assess organ function and find any anomalies or changes that might point to the existence of amyloidosis, imaging examinations like radiographs (X-rays), ultrasounds, or others may be employed.

  • Biopsy: A tissue sample may be required to confirm the amyloidosis diagnosis. A biopsy involves removing a tiny piece of the afflicted tissue, such as the liver or kidney, and examining it under a microscope to check for amyloid plaques.

  • Genetic testing: In cases of familial amyloidosis, genetic testing can help identify dogs at risk for developing the condition and guide breeding practices to reduce the incidence of the disease.

Is There Any Cure For Amyloidosis In Dogs?

Currently, there is no cure for amyloidosis in dogs, and treatment options are limited to managing the symptoms and slowing the progression of the disease. Some of the treatment options for amyloidosis in dogs include:

  • Medications: Depending on the organs affected by amyloidosis, your veterinarian may prescribe medications to manage symptoms such as vomiting and diarrheaMedications to treat kidney dysfunction and medications to reduce inflammation may be prescribed to slow the progression of the illness.

  • Diet: A special diet may be recommended to support organ function and prevent further damage. A low-protein diet may be prescribed for dogs with renal amyloidosis to reduce the workload on the dog’s kidneys.

  • Fluid therapy: Due to vomiting or increased urine output, dogs with amyloidosis may become dehydrated. Hydration levels can be restored, and fluid therapy can promote kidney function.

  • Surgery: To eliminate amyloid deposits from impacted organs in some circumstances, surgery may be required. Surgery is generally not advised, though, unless the advantages outweigh the dangers.

  • Supportive treatment: This may be required to control symptoms and enhance the dog's quality of life, depending on the disease's severity. This can entail managing discomfort, keeping an eye on vital signs, and giving drinks and food when necessary.

It is significant to remember that the course of treatment for canine amyloidosis may change based on the underlying etiology and the organs affected. To create a personalized treatment plan for your dog, it is crucial to collaborate closely with your doctor.

Prevention Tips

Unfortunately, there is no known way to prevent amyloidosis in dogs, as the causes of this condition can be genetic or related to underlying chronic inflammatory conditions. However, early diagnosis and immediate veterinarian treatment can help control the symptoms and stop the disease's development.

Regular physicals and blood tests can help identify early indications of organ malfunction or other alterations in the body that could be markers of amyloidosis. 

Additionally, keeping up with routine vaccinations and parasite prevention can help prevent infections that can contribute to the development of secondary amyloidosis.

Having your dog genetically tested to look for any potential mutations is advised if you have a breed that is known to be susceptible to familial amyloidosis. Dogs at risk of amyloidosis can be identified via genetic testing, and this information can be used to inform breeding decisions and lower the prevalence of the disease.
