West Allis Animal Hospital has been dedicated to providing exceptional veterinary care for pets since its founding in 1892. Originally established as Dr. Sullivan's Veterinary Hospital, the practice has evolved from equine medicine to become a trusted full-service animal hospital serving cats, dogs, and ferrets in West Allis, Wisconsin. Over more than a century, we have maintained a steadfast commitment to advancing with veterinary medicine's innovations while preserving our core values of compassion and community service. Our team of skilled veterinarians and support staff prioritizes personalized care, utilizing modern facilities and advanced diagnostic tools to ensure comprehensive treatment for every patient. We emphasize preventive care, wellness exams, and urgent pet care, guided by the understanding that pets are integral family members requiring lifelong health partnerships.

Through ownership transitions and technological advancements, our mission to deliver high-quality medical and surgical services has remained unwavering. The hospital's 2007 relocation to a state-of-the-art building reflects our dedication to combining historical legacy with contemporary veterinary practices. We serve West Allis and neighboring communities, offering dental care, surgical procedures, and specialty medications through both in-person and digital platforms.
