Our 24/7 emergency service treats urgent conditions like trauma, poisoning, and respiratory distress. Board-certified emergency clinicians use advanced diagnostics including CT scans and STAT lab testing to stabilize critical patients. The ICU provides continuous monitoring and oxygen therapy for post-operative or severely ill pets, with real-time updates for pet owners throughout treatment.
Cardiology
Board-certified veterinary cardiologists diagnose and manage heart conditions using echocardiography and Holter monitoring. We treat arrhythmias, heart failure, and congenital defects through medication management and collaborative care with internal medicine specialists. Our team provides comprehensive evaluations for breeds predisposed to cardiac disease, ensuring early intervention and improved quality of life.

Light sedation ensures clear imaging for anxious patients, while rapid turnaround supports timely treatment decisions for both emergency and specialty cases.
