Dr. Runge and Dr. Ateca going the extra mile, allowing a client to visit and sit with their baby in the ICU, while walking the client through the procedure and treatment plan post surgery. This client came all the way from PA to work with Dr. Runge and our surgery team who removed several tumors from the patients body. 💜
Exceptional care, without exception!

"The snow is too deep for little doggies like you," says mom.
When the snow finally stopped, mom put on her Antarctica jacket, zipped us in, and showed us how the snow is "so big." ~ Gus

“See something do something. Why wait?! Aspirate!” - a message from Dr. Sue Cancer Vet 💜
Regularly checking your pet for lumps and bumps can be all the difference in saving and/or extending their quality of life. If you find a lump, don’t wait for it to grow, get it checked by your veterinarian. Not only to get a proper diagnosis, but for the peace of mind of knowing, before it becomes a larger problem, if it’s a problem at all! 💜

In this recap of Episode 62 of our BTS Series on YouTube, Giger, our facility managers Doberman Pinscher, had a spinal surgery to help manage his Wobblers Syndrome.
Wobblers is a neurologic disorder in dogs that causes compression on the spinal cord, leading to unsteady gate, pain, and in severe cases, can cause complete paralysis.
According to Mark, Giger went on to live another happy and (mostly) healthy 3 years, with no issues in mobility. He told us after recovery, Giger was back to playing with his younger house mates and had “puppy like” energy Mark hadn’t seen from him in a long time. Unfortunately, Mark lost Giger this past Summer but he told us the surgery made all the difference in Gigers quality of life the last few years he was alive. 💜
