We went to see Dr. Neis with our Sheltie Simba. Sudden onset. Despite Dr Becky's help we lost Simba to CHF. She also took two lumps off of our Kate, and kept us informed while waiting for the pathologists report. The surgery was well done, and Kate didn't even wear an E collar. So well done. We have 3 Shelties and I would trust Dr Becky with all of them. She treated us like family.
