The Sagamore Hills Animal Hospital offers a wide range of veterinary services for your pet cat or dog.  Our clinic's services span your pet’s life, beginning with neonatal care and moving through adolescent care, surgical neutering, active adulthood, and senescence to end of life care, when we provide geriatric therapy, palliative care and euthanasia services.  We know that your pet is truly a member of your family, and we treat each pet as such.   Because we value our patients, we are selective in choosing our employees, and this is reflected in the quality of service we provide.  We are proactive and pro-pet in our thoughts and actions, and we provide treatment and counseling for each individual pet within the framework of humane care.   Please contact us to schedule an appointment for your pet and, if desired, a tour of our facility.

Flea, tick, and mosquito season has started.  In the last month, we have had four heartworm positive dogs, two of which have started treatment with adulticide therapy.  For our dog patients, we recommend and dispense NexGard for flea and tick protection.  NexGard is a chewable, once-a-month treat to be given by mouth.  For heartworm prevention we dispense Heartgard oral chewable, once-a-month treats or Revolution that is applied topically once monthly.

The Sagamore Hills Animal Hospital Virtual Tour is up and running,  It can be found under the New Patient Center Tab and going to the third option.
