My dog came down with a sudden stomach upset the other morning, was drooling, shivering and lethargic. I called Horizon and they took me in within a half hour from my call. Dr. Penn was straight forward, logical and empathetic and ended up keeping Caesar (just 1 year old) for a few hours for observation after treating him. When I called in the afternoon to check on Caesar, they got right on the phone immediately and answered my questions. Caesar came home feeling much better that evening, and I certainly appreciated the follow up phone call the next day! I have 3 dogs, various breeds, and they always do a great job caring for them. I highly recommend the staff at Horizon Animal Hospital, they are top shelf!
