Understanding Kidney and Urinary Health in Newfoundlands

Quick answer

Newfoundlands are prone to specific urinary and kidney conditions, including the formation of cystine stones and primary kidney disease. By monitoring your dog for changes in urination habits, energy levels, and appetite, you can work with your veterinarian to manage these risks effectively. Early detection is the most important factor in maintaining your dog's quality of life.

Urolithiasis

Urolithiasis refers to the formation of stones within the urinary tract. In Newfoundlands, this is a recognised tendency in the breed, specifically regarding the development of cystine uroliths. These stones form when cystine, an amino acid, accumulates in the urine and crystallizes. This is well recognised in the breed, and a genetic mutation test is available to identify dogs that may carry the trait.

At home, you might notice your dog straining to urinate, producing only small amounts of urine, or showing signs of discomfort or pain during the process. You may also see blood in the urine. If you notice these signs, your vet will perform a physical exam and likely use imaging such as X-rays or ultrasound to look for stones. A urinalysis is essential to check for crystals and signs of infection. The urgency of this condition depends on whether the dog can still pass urine. If your dog is unable to urinate at all, this is a medical emergency that requires immediate intervention.

Chronic Kidney Disease

Chronic kidney disease involves the gradual loss of kidney function over time. In Newfoundlands, this is associated with primary glomerulopathies, which are conditions affecting the filtering units of the kidneys. This is a recognised tendency in the breed, though how this passes down is not settled.

Early signs of kidney disease are often subtle. You might notice your dog drinking more water than usual or urinating more frequently. As the condition progresses, you may see a decrease in appetite, weight loss, or a dull coat. Your vet will use blood tests to measure kidney values and a urinalysis to check how well the kidneys are concentrating urine. Blood pressure monitoring is also a standard part of the assessment, as high blood pressure is a common complication of kidney disease.

Monitoring Your Newfoundland

Maintaining a healthy body condition score is vital for your Newfoundland. Excess weight puts additional strain on the body, including the kidneys. Regular skin and coat checks allow you to monitor for signs of dehydration, such as skin that does not snap back quickly when gently lifted. Establishing a behavior baseline is also helpful. By knowing what is normal for your dog, you will be the first to notice when something is wrong, such as a sudden lack of interest in play or a change in temperament.
