  • I cannot say enough great things about the care my dog, Cow Cow, received this past week and weekend. The care, compassion and kindness everyone showed is why I will never take my animals to another vet. Dr. Melissa and her team of techs were truly amazing and provided the best care Cow Cow could ever have had. When I had to make the difficult decision to let Cow cross the rainbow bridge, Dr. Katelyn and the rest of the staff were truly amazing.
