Emergency Mystery Solved: Ari’s New Lease on Life

After the removal of a paraganglioma and pulmonary carcinoma in September 2025, 15-year-old Ari seemed to be on the mend. But within weeks, new fever and pain symptoms led his owners to take him to the emergency room.

On the third ER visit with the same symptoms, an anxious Ari was admitted to the hospital for the weekend, where he was put under Dr. Jenise Carter’s care.

“Dr. Carter went above and beyond to ensure Ari was well cared for,” shared his owner, Jenny Beguiristain. “She was incredibly patient and thoughtful, personally calling us twice a day to provide updates and allowing us to visit to try to encourage Ari to eat.”

Dr. Carter’s careful attention ultimately led to the diagnosis of a urinary tract infection, which allowed Ari to receive the treatment to finally heal.

“On his walks, we noticed Ari’s urine was foul-smelling and dark colored,” Dr. Carter said. “We performed a urinalysis and urine culture that revealed a marked amount of E. Coli. In addition to antibiotics, Ari was treated with pain medications, anti-nausea medications, and an appetite stimulant.”

Today, Ari is nearly 16 and back to playing on the beach, patrolling the backyard, and running errands around town.

“My little sidekick has plenty of energy and a new lease on life,” Beguiristain said. “We are so grateful for Dr. Carter’s dedication, professionalism, and genuine care. It made a stressful situation much more manageable.”
