Kidney Disease in Dogs and Cats
Chronic kidney disease is one of the most common illnesses in older cats and a frequent concern in senior dogs. Because the kidneys can lose much of their function before signs appear, early detection makes a real difference. The Pet Clinic offers in-house kidney screening and long-term management to help pets in Omaha, NE live longer, more comfortable lives.
What Do the Kidneys Do?
The kidneys filter waste from the blood, balance fluids and electrolytes, help regulate blood pressure and produce hormones that support red blood cell production. When they stop working efficiently, toxins build up and pets begin to feel unwell.
Types of Kidney Disease
Chronic kidney disease (CKD) develops gradually over months to years and is most common in senior pets. Acute kidney injury happens suddenly and can be caused by toxins such as antifreeze, lilies in cats, grapes and raisins in dogs, certain medications, infections or urinary blockages. Acute kidney injury is an emergency.
Signs of Kidney Disease
- Drinking and urinating more than usual
- Decreased appetite or weight loss
- Vomiting or nausea
- Lethargy and weakness
- Bad breath with an ammonia odor
- Poor coat condition
Early Detection Through Screening
Routine bloodwork and urinalysis during wellness exams are the best way to catch kidney disease early. Our in-house laboratory measures kidney values, including the sensitive SDMA marker, and urine concentration so we can see changes before your pet feels sick. We recommend at least yearly screening for senior pets. Ultrasound and X-rays help evaluate kidney size and structure and look for stones.
Managing Kidney Disease
While chronic kidney disease cannot be reversed, treatment can slow its progression and keep pets comfortable. Plans may include:
- Prescription kidney diets through nutritional counseling
- Fluid therapy, including subcutaneous fluids at home
- Medications for nausea, appetite, blood pressure and phosphorus
- Regular rechecks to monitor bloodwork and adjust care
Good oral health also matters, since dental disease can add stress to the kidneys. We make rechecks easier on anxious pets with low stress handling. If your pet has been diagnosed elsewhere, we welcome second opinion visits, and our team provides compassionate guidance through end of life care when the time comes. See all conditions we treat.
