Kidney Enlargement is also known as renomegaly in dogs.
Renomegaly is a condition characterized by an abnormal enlargement of one or both kidneys, which can be detected through abdominal palpation, ultrasound, or X-ray imaging. This condition impacts multiple body systems, including the respiratory, nervous, hormonal, urinary, and digestive systems.
It's important to note that renomegaly isn't limited to dogs; cats can also experience this condition.
Symptoms Of Kidney Enlargement
There are times when a dog may not show any symptoms at all. However, some of the more common signs observed in dogs with renomegaly include:
- Increased body temperature
- Mouth sores
- Back or belly pain
- Extreme thirst
- Increased urination
- Bad breath odor
- Stiff walking
- Vision problems
- Appetite loss
- Weak or rapid pulse
- Staggering
- Vomiting
- Nausea
- Weakness
- Dark urine
- Dizziness
- Coma
- Convulsions
Types Of Kidney Enlargement
Acute kidney enlargement typically occurs suddenly and is often triggered by trauma or a severe illness, making it easier to identify and diagnose the cause.
On the other hand, chronic kidney enlargement develops gradually over time and is more challenging to detect. By the time noticeable symptoms appear, significant kidney damage has often already occurred.
Causes Of Kidney Enlargement In Dogs
Acute Kidney Enlargement:
- Infection
- Injury
- Kidney stones
- Urinary obstruction
- Exposure to toxins
- Acute renal failure
Chronic Kidney Enlargement:
- Certain dog breeds are more susceptible to kidney disease, such as Beagles, Terriers, Chow Chows, Cocker Spaniels, Bernese Mountain Dogs, Dobermans, Lhasa Apsos, Retrievers, Schnauzers, Corgis, Shar-Peis, Rottweilers, Samoyeds, Newfoundlands, Shih Tzus, Malamutes, and Poodles.
- Advanced age
- Tumors
- Lymphoma
- History of renal disease
- Chronic kidney infections
Diagnosis Of Kidney Enlargement
A comprehensive blood workup will be conducted, including a chemical blood profile, complete blood count, and urinalysis. Additionally, a palpation exam and X-rays will help your veterinarian assess the kidney's size and diagnose the condition.
If cancer is suspected, thoracic X-rays will be used to check if the cancer has spread. Ultrasound, which utilizes sound waves, will provide detailed images of the internal organs, helping the veterinarian assess the extent of kidney swelling or identify abnormalities in other organs.
Sometimes, your dog may undergo renal fluid aspiration and a biopsy for further evaluation.
Treatment Of Kidney Enlargement In Dogs
Your dog will typically receive outpatient care unless it is experiencing dehydration or renal failure. Treatment starts with identifying and addressing the underlying cause, maintaining proper fluid balance with IV fluids if needed, and restoring minerals and electrolytes. A regular diet and normal exercise will be recommended if your dog is otherwise in good health.
Your vet will prescribe Medications and it will depend on the cause of renomegaly, but any drugs that could harm the kidneys should be avoided.
Management Of Kidney Enlargement In Dogs
Your veterinarian will schedule regular follow-up visits to monitor your dog's physical recovery and hydration levels.
If your dog's symptoms reappear, it's crucial to contact the veterinarian right away. Renomegaly can lead to serious complications, such as kidney failure and hormone imbalances that may resemble hormone-producing cancers.
