01

Surgery center for dogs and cats

A full-service surgery center for dogs and cats — and we are genuinely comfortable with high-risk anesthesia and specialist surgery. A full-time board-certified soft-tissue surgeon and veterinary anesthesiologist plan complex cases together, with ABG-informed anesthesia, Harmonic & LigaSure instrumentation, an on-site defibrillator and a CPR-ready team.

02

Pre-anesthetic assessment

For senior pets, cardiac patients, brachycephalic breeds or other high-risk animals we use bloodwork, ABG, echocardiography when indicated, and airway assessment to tailor the anesthetic protocol.

03

Intra-operative monitoring

Multi-parameter monitoring at every anesthetic event: ECG, SpO2, EtCO2, blood pressure, temperature and anesthetic depth — with a defibrillator and a CPR-trained team ready.

04

Advanced vessel-sealing instruments

Harmonic blade and LigaSure for soft-tissue, orthopedic and oncologic surgery. Instruments are chosen for the case, not as a one-size default.

05

Complex soft-tissue and emergency procedures we take on

Beyond routine surgery, we accept complex and emergency cases many general practices decline. Every case is co-planned by surgeon and anesthesiologist.

  • GDV — decompression, derotation and gastropexy
  • Perineal herniorrhaphy in dogs (internal obturator transposition when indicated)
  • Diaphragmatic herniorrhaphy — traumatic and congenital
  • Intestinal resection & anastomosis — obstruction, mass, ischemia
  • Nephrectomy for non-functional or diseased kidneys
  • Cystostomy / cystotomy — stones, masses or ectopic ureter
  • Perineal urethrostomy (PU) in cats with recurrent obstruction
06

Appointments preferred — walk-ins accepted, wait times vary

Our work is deliberate and equipment-heavy, so we schedule by appointment. Walk-ins are accepted but may wait. Booking ahead reserves team time and instruments for your pet.
