Small Animal - About Us


Heartland Animal Hospital originated as the Listowel Veterinary Clinic, a primarily large animal hospital, back in the 1960s.  The clinic moved to its now current location in 1979, and expanded to offer more and better service for small animal patients and their owners.  Our recent expansion in 2010 will help ensure we are able to provide exceptional patient care and client service well into the future.


We are a full service veterinary hospital, with 24 hour emergency service for our clients.
