1. Protein-Losing Nephropathy (PLN)

PLN is a serious kidney disorder. Affected dogs lose protein through their kidneys, leading to kidney failure over time. Symptoms of PLN include vomiting, diarrhea, weakness, and weight loss. Increased drinking and urination are also common.

PLN is an adult-onset disorder, usually occurring between the ages of 4 and 8 years. The severity of the condition can vary. Mild cases can often be managed with a low-protein diet and medication, while more severe cases may significantly shorten a dog's life expectancy. Early detection through urinalysis testing is crucial for effective management. Both Soft Coated Wheaten Terriers and Airedale Terriers are prone to this condition.

The age of onset ranges from 6 months to 11 years. Prognosis varies depending on the underlying cause, and treatment can include dietary changes, medications, and supplements.

3. Addison's Disease Also known as hypoadrenocorticism, Addison's disease occurs when the adrenal glands fail to produce sufficient hormones, such as aldosterone and cortisol. Symptoms may include lethargy, vomiting, diarrhea, and increased thirst. Addison's Disease tends to show up in young to middle aged dogs and is more common in females. With the correct treatment, the prognosis is generally good. Annual blood tests are recommended to screen for this disease.

4. Renal Dysplasia (RD)

Renal dysplasia is a developmental abnormality of the kidneys that can lead to early-onset kidney failure. Symptoms can include decreased appetite, lethargy, bad breath, vomiting, excessive thirst, frequent urination, and poor growth in puppies.

The condition can be diagnosed at any age, depending on its severity and the number of affected kidneys. It's usually progressive and can shorten a dog's lifespan considerably. Blood tests and ultrasounds are helpful for diagnosing this congenital defect.
