John G. Manning, DVM, M.S.

Texas A&M University

 

A native Texan, from Corsicana, Dr. John Garrett Manning has been practicing Veterinary Medicine for 25 years, He attended Texas A&M University where he earned two undergraduate degrees a Master of Science and a Doctorate in Veterinary Medicine. Dr. Manning taught at Texas A&M for seven years where he won multiple teaching and research awards, including the Honor Professor Award and the Award for Excellence in Undergraduate Teaching. He also conducted experimental research and published refereed scientific journal articles in multiple areas of research – ranging from avian diseases to animal and human instincts and behavior. He has also published three books. Dr. Manning has a special interest in “integrated medicine” (a mix of western medicine with acupuncture/acupressure, herbology and energy balance healing) for a more holistic and overall health approach to Veterinary Medicine. His integrated treatment expertise enhances Night Watch’s medical repertoire available for our patients and offers other complementary or alternative options when conventional medications aren’t a complete solution to a pet’s health problems. He has special expertise and interest in spinal cases (IVDD – intravertebral disc disease) and all osteoarthritis conditions involving tendons, ligaments, sinews, bones and joints. When at the age of four he watched a veterinarian perform a “miracle” on a downer cow with milk fever, bringing it “back to life” (with a liter of calcium gluconate IV). At that moment a spark was lit inside the young John Manning. This incredible experience is a large part of what made him decide to be a veterinarian and become the dedicated animal doctor that he is today. When not at work you can find Dr. Manning cheering on his son (the budding golf star), playing guitar, writing songs or mastering his swing on the golf course. He is a member of both TVMA and AVMA. His well-rounded approach to medicine helps this friendly Texan care for your pets and find solutions for your companion’s health that fit with your family.
