Jeff Wiemann

Pet- Ned, English Cocker Spaniel, 8 years old. He is a very loving and silly dog who loves to chase squirrels and on the couch.

When not working I enjoy spending time with my wife and dog. I also read a lot of fiction, watch movies and shoot targets for fun with shotguns and pistols.

I started out doing scientific research but was not fulfilled. The research world was just too far from everyday things in life that matter to me. Practicing medicine is very real and definitely what I should be doing with my life. I strive to become a better veterinarian and person, every day.

I really like cats, but dogs are my favorite animal by far. I am fascinated by the fact that  humans and dogs have been living and working together for over 100,000 years. The bond between dogs and people is unlike that between us and any other animal. I can't imagine living without dogs.
