Pet Emergency? Call us right away at (303) 499-0199!

Life is an adventure that is enhanced tremendously by the loyal and loving companionship of our pets. They give so much but ask for so little in return.  Our mission at Sunshine Animal Hospital is to give them a voice so that their individual and unique health needs are being assessed and met with a focus on compassion and expertise in care, all while keeping in mind the goals of the caregiver. Sunshine Animal Hospital, located in Superior, Colorado, is a single doctor, privately owned practice.  We feel that practicing medicine in a smaller setting allows for a more personal connection, better care and allows every patient to have a health care plan that is customized to them.

Sunshine Animal Hospital is a full-service animal hospital and welcomes both emergency treatment cases as well as pet patients in need of routine medical, surgical, and dental care. Dr. Kristy Kreutzer has years of experience treating serious conditions and offering regular pet wellness care. Beyond first-rate pet care, we make our clinic comfortable, kid-friendly, and calm, so your pet can relax in the waiting room and look forward to meeting our Superior veterinarian.

We are happy to offer a number of resources that enable you to learn about how to take better care of your pets. Please feel free to browse our site, particularly the informational articles. The best veterinary care for animals is ongoing nutrition and problem prevention, so becoming knowledgeable about preventative pet care is essential to the ongoing success of your animal’s health. If you have any questions, call (303) 499-0199 or email us and we'll promptly get back to you. Our Superior veterinary office is very easy to get to -- just check out the map below! We also welcome you to subscribe to our newsletter, which is created especially for Superior pet owners.

At Sunshine Animal Hospital, we treat your pets like the valued family members they are.

  • Dr.
    Kristy Kreutzer
    Owner, Veterinarian

    Dr. Kreutzer was born and raised in Colorado. As a young girl, she always loved animals and generally had a menagerie of animals at home. She grew up riding horses and was a dedicated member of the Westernaires precision drill horse riding organization throughout her childhood. Kristy was the first member of her extended family to go to college, and she was drawn to the medical field. Early in college, she owned a puppy that ended up having a developmental malformation and unfortunately had to be euthanized. It was this challenging event in her life that caused her to realize her calling was in veterinary medicine.

    We have seen Dr. Kristy on several occasions and she is excellent. She understands the health of the dog and how choices fit in with the family. She is kind and knowledgeable and we love her!

    Rene Bachmann Sias

    Dr. Kreutzer’s level of compassion for animals beats any other vet I have brought my dogs to. I tend to be a neurotic dog mom and I ask a lot of questions, not only does she answer all of my questions but she has been able to talk me through some scary procedures and help ease my mind when I was going through some hard times with my dogs. I wouldn’t have anyone else work with my fur babies!

    Mimi Pfaff

    We are incredibly grateful to have Dr. Kruetzer as our dogs vet and highly recommend her. She takes her time to listen to our updates and concerns, and does a thorough job explaining all our options and their related costs.Above all else, Dr. Kruetzer truly cares about my dogs and treats my family with incredible compassion and kindness. She saw our Bullmastiff, Lando, through years of treatment after he was diagnosed with Liver Disease. Dr. Kruetzer fought for Lando throught this journey, and supported us in all of our decisions. We have immense trust and respect for her; there are no words to explain how much we appreciate all she's done for us and our fur-babies. I can't recommend any vet more highly!

    MacKenzie Houpt

    This review is long over due, Dr. Kreutzer will understand. She is the BEST veterinarian around. She is smart, kind, caring and compassionate. I am so happy she now has her own clinic. She has taken amazing care of my kitties for many years and I am so grateful she was there for them...and me...when it was time for Jake Michael and Zöe Belle to cross the Rainbow Bridge. Her focus is always what is best for your pet and she will always take the time to answer your questions and listen to your concerns.

    Shannon Mayes

    I was so excited to finally have a vet in Superior, and after seeing Dr. Kreutzer I could not be happier! She is so kind, so caring, and so patient. Everyone in the practice was so warm and friendly — it was hands down the best vet experience I’ve had. My kitty has a number of medical issues and it was so nice to have someone who really understands and cares. It’s a small practice which I love, because you really get a personal experience. We are so lucky to have to Dr. Kreutzer and her practice in our town and I can’t recommend her more highly!

    Stefanie Clarke

    Dr. Kreutzer is kind, compassionate, and the best vet care I've had for my dog.  I have lived in 4 states over my dog's 13 years and moved away from Colorado 2 years ago. We miss her so much.  She always knew how to reduce mine and Goochie's stress when Goochie had any issues.  You could not be in more knowledgeable and loving hands with Dr. Kreutzer as your vet!!!

    Kate Sandonato

    My first impression of Dr. Kreutzer was that of a very bright, caring, experienced doctor. It was, and is, very clear that she cares about both her patients and their parents, and is extremely knowledgeable. I've experienced a broad spectrum of issues with Dr. Kreutzer- from happiness of having her examine my newly adopted pup, to the crisis of a rattlesnake bite, to the time for her to euthanize my beloved old dog. She handles all these situations with professionalism, compassion, and patience. In all situations she explains what she is doing and why. She is extremely efficient. I simply cannot say enough good things about Dr. Kreutzer, she is simply the best and I would highly recommend her to anyone seeking excellent care for their pets.

    Louise Preyer

    I could not be happier with my experiences with Dr. Kristy Kreutzer. I would highly recommend her! Dr. Kreutzer has taken excellent care of my dogs the past four years. She listens to my concerns and is very thorough with her exams. She walks me through each process and provides me with enough details that eases my mind. My dogs are like my children and I am so thankful that Dr. Kreutzer understands that.
