Pet Physical Exam
Annual wellness exams detect early health issues through comprehensive assessments. Our veterinarians check ears, eyes, teeth, internal organs, and skin condition to maintain pet health. Early disease detection prevents serious complications and extends animal lifespans through timely interventions.
Pet Vaccinations
Core and elective vaccinations protect pets against infectious diseases. We administer distemper, rabies, and leptospirosis vaccines for dogs, plus feline leukemia and panleukopenia vaccines for cats. Our protocols follow AAHA guidelines for optimal disease prevention.
Pet Surgical Procedures
In-house surgical suite handles spays, neuters, tumor removals, and trauma repairs. Advanced anesthesia monitoring ensures patient safety during procedures. Post-operative care includes pain management and recovery follow-ups for surgical success.
Pet Dental Treatments
Professional dental cleanings under anesthesia prevent periodontal disease. We remove plaque, polish teeth, and address oral infections to prevent systemic health complications from dental bacteria. Annual dental exams maintain oral health.
Pet On-Site Lab Services
In-house laboratory processes bloodwork, urinalysis, and parasite screenings. Immediate results enable rapid diagnosis of infections, organ function issues, and endocrine disorders. Point-of-care testing supports timely treatment decisions for critical cases.

Questions
How should I care for my pets' teeth?
Brush daily using pet-safe toothpaste and special brushes. Combine with professional cleanings to prevent periodontal disease and maintain oral health.
What causes my pet's bad breath?
Bacterial buildup in the mouth produces sulfur compounds causing odor. Regular brushing and professional dental cleanings effectively treat halitosis.
How can I help my pet lose weight?
Consult us for diet assessment and exercise plans. Prescription weight management foods combined with daily activity improve pet health.
Why does my pet need yearly bloodwork?
Annual blood tests detect early organ dysfunction, infections, and metabolic disorders. Early diagnosis enables effective treatment of potential health issues.
Can my cat drink milk?
Most cats develop lactose intolerance after weaning. Milk consumption commonly causes gastrointestinal upset and should be avoided.
What are heartworms and how can they be prevented?
Heartworms are parasitic worms transmitted by mosquitoes. Monthly preventatives like Heartgard effectively protect pets from this serious infection.
