Services
Vaccinations
Vaccinations protect pets from preventable diseases through tailored immunization protocols. We offer core vaccines like rabies, distemper, and bordetella, along with lifestyle-specific vaccines for at-risk animals. Our AAHA-accredited standards ensure proper vaccine handling and administration, helping pets build immunity while complying with state regulations. Regular vaccinations form the foundation of preventive care.
Dental Care
Comprehensive dental services include cleanings, extractions, and periodontal treatments using digital radiography. Our process combines ultrasonic scaling, polishing, and fluoride application to address plaque buildup while minimizing anesthesia risks. Pre-operative bloodwork ensures safety, and we provide post-operative care guidance. Regular dental maintenance prevents systemic infections and supports long-term health.
Surgical Procedures
We perform soft tissue and orthopedic surgeries in our modern surgical suite with advanced monitoring equipment. Pre-anesthetic blood testing identifies risks, while tailored anesthetic protocols prioritize patient safety. Post-operative pain management includes multimodal therapies like laser treatment and prescribed medications. Our surgeons handle everything from routine spays/neuters to complex tumor removals with specialized aftercare.
Acupuncture
Acupuncture services use needle insertion at specific points to treat musculoskeletal, neurological, and chronic conditions. This complementary therapy offers pain relief for arthritis and intervertebral disc disease, often reducing medication needs. Our certified practitioners integrate acupuncture with traditional treatments, providing holistic options for pain management and improved quality of life.
Cold Laser Therapy
Cold laser therapy employs Class IV light to reduce inflammation, accelerate healing, and alleviate pain. This non-invasive option treats conditions like arthritis, soft tissue injuries, and post-surgical recovery. The treatment stimulates cellular regeneration without requiring anesthesia, offering a safe alternative for pets with medication sensitivities. Sessions are typically short and well-tolerated.
