The Office Dog

Since adopting Enzo at 10 months old in 2015, he has become much more social and comes to work every day with Dr. Eckstein and hangs out (i.e. sleeps) in the doctor’s office. He loves to go to the dog park to see his friends and roll in the grass. He has food allergies among other things and eats a special diet. He is afraid of the Albertson’s delivery trucks, the mop bucket, and wet floors.


The Office Cat

We inherited Biscuit in 2018, at 19 years old, she is looking pretty good. She lost one eye to a Coyote a long time ago, which we believe may have contributed to her feisty nature. Besides a mild hairball issue, she is in pretty good health and is settling into her new retirement digs quite nicely.



Office Cat

Max passed away in 2016 at the ripe old age of 16 years old. He was the best “Office Cat” we could have ever asked for. He fit in perfectly with our hospital, wandered around happily, did not mind dogs, shared a bed in the office with Enzo, Dr. Eckstein’s dog. He kept us all smiling. He was a blessing and we were happy to give him the comfortable retirement he deserved.
