i dont for Fort Collins area but if you were in the springs i would tell you to go to Crossroads Animal Hospital. I believe (dont quote me) that there is a crossroads in your area. You can look them up online and they give all the locations.
I've worked with Dr. Berglund, (who is now unfortunately in Denver), and Dr. Cat Cross. Dr. Cross is one of the co-owners of this practice. She is wonderful as is the staff. We don't see eye to eye on diet,(I feed raw), but I think she's a great vet regardless. The care is top-notch, some times that can be a little pricey but I'm confident that my dog gets the best care at this practice. If you do end up working with Dr. Cross, tell her Sarah and Khyber the GSD sent you!
Here's also a suggestion for low cost care. I have a friend who is quite the expert on dog services in Fort Collins, and for low-cost veterinary care, he highly recommends Elder Pet Care with Dr. Thomas. This practice is in north Fort Collins, just a tad north of Old Town. They don't have a website that I can find, but here's a link with their address and phone number. Elder Pet Care - Google Maps
I highly recommend the Colorado State Veterinary Teaching Hospital. We live in Denver and I have taken several of our animals (who had out of the ordinary issues) there with tremendous success. Veterinary teaching hospitals are where the latest treatments are developed. They also have state-of-the-art equipment. When my vet has an issue that he needs information on, he calls CSU.
Thanks for all of the info. Gunner is doing really well. He came from California but absolutely loves running in the Colorado snow! I wanted to start the search for a vet early. I appreciate the feedback.
