The University of Florida Large Animal Hospital is one of the few practices in Florida that have veterinarians specializing in equine and other large animal skin diseases. Florida’s tropical climate promotes skin infections in animals, leading to hard-to-diagnose diseases. UF’s Dermatology service and equine veterinarians treat the most complicated dermatology cases.
