Spaying and neutering are surgical procedures intended to render your pet incapable of producing puppies or kittens by the removing of the organs of reproduction.


Exam Rooms and Pharmacy
Our five regular exam rooms provide a quiet place to discuss all your pet’s needs. After a technician has obtained the accurate weight and temperature, the Doctor will arrive and begin the physical examination. Many problems can be diagnosed here and minor treatments and vaccinations will be performed in the room.
The center of any veterinary hospital is the treatment area. This is where animals that require more extensive treatment or hospitalization will receive the care they need. Our treatment area is fully equipped to handle every contingency.
Lab and X-rays
Located behind the exam rooms is our in-house laboratory. This lab is capable of performing many tests and reporting the results in less than 20 minutes. Tests include blood, urine, fecal, heartworm and others. Samples that require additional testing will be sent out to a local veterinary laboratory.
Special Procedures
Special Procedures is a room next door to the main Surgery. This is where we perform ultrasounds as well as minor anesthetic procedures such as teeth cleaning and polishing, skin biopsies and small growth removals, cleaning and suturing of minor wounds, etc.
The main Surgery is a special room where all major sterile procedures are performed. This includes routine spays and neuters as well as advanced abdominal, exploratory and other surgeries. This room is equipped with sophisticated equipment including life support systems, respirators and monitors.
 Pet Hotel & Boarding
At Horizon Animal Hospital, as one of the leading Scottsdale pet hotel, we are proud to offer state-of-the-art boarding accommodations.

Very professional from start to finish. I brought my dog in for a dental cleaning. My estimate was clear, as well as what was going to take place with my beloved dog. I was also able to have a couple of extra items (growths) looked at and taken care of. I’ve always had first class service here.

And today, I received a follow up call to make sure my dog was feeling well. I would absolutely recommend Horizon to anyone.

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!

Dr Beth and her staff are wonderful!;They are extremely caring & compassionate. We’ve been through a lot together over many years, everything from cancer with two of my girls to possible alzheimers with my cousin’s cat. Dr Beth amputated my Peanuts rear leg, which saved her life. I had Peanut for another 12 years. I will always be extremely grateful to her & her staff for always being there when my fur babies needed her.

If you’re looking for an extremely knowledgeable vet, whose very skilled, look no further, you’ve found her.

First, we loved the cleanliness and beauty of the hospital waiting room and examining room and the friendliness and professionalism of the staff. It was a pleasure to meet Dr. Beth. We had heard so many nice things about her and what a great veterinarian she is and how kind she is with the animals. We found this all to be true. She was so easy to talk to and answered all of our questions and concerns. We look forward to having her take care of our little Heidi in the future.

We brought Daisy in with no appointment as she got very sick unexpectedly. Even though it was shortly before they were closing, the vet still took the time to do x-rays and check her thoroughly without rushing. Daisy was treated and doing much better right away. So thankful for the wonderful and caring staff. Our experiences with all of our dogs have always been positive here. We have been going here for several years, and have never had a complaint.
