Current News

Roy celebrated his first birthday on July 10, 2019. The first year has definitely been an adventure as Roy has been very busy learning how to be a veterinarian’s dog. He fully thinks one of his main jobs is to be the official greeter at the clinic to all clients and patients alike and still is learning that not all patients are excited about his enthusiastic welcome. Farm calls are a big favorite, especially if there are full stock tanks or even better a muddy pond to jump into. Learning to wait patiently in the truck presented a small challenge and fortunately only a couple of ink pens, plastic straws and one seat belt were injured in the process. He occasionally attends additional obedience classes. He thinks they are just a chance to show off, in reality they are used to help his mother cope with a young man who thinks he is still a puppy.
