Please welcome Addison Heidemann to the Steinbeck Peninsula Equine Clinics team!

Addison grew up in Sunnyvale and still lives there. She attended Foothill College for some time after high school, but decided to put schooling on hold, in order to make horses her full-time career. As a horse trainer, Addison works with lots of horses in the area and rides nearly every day. She enjoys training horses and teaching lessons. Addison has two Quarter Horses of her own: an 18-year-old gelding named “Jetty” and a 10-year-old mare named “Ginger.” She currently rides Western, primarily, but with over 15 years of riding experience, she has also competed in the English world as a Hunter/Jumper.

After working as a Veterinary Assistant in small animal healthcare, Addison felt she could contribute more in equine healthcare, so she applied to Steinbeck Peninsula Equine Clinics. She hopes to eventually have her own ranch, so all that she is now learning in the field as an Equine Veterinary Assistant with the SPEC team will be put to good use, some day!

While Addison is very committed to her life with horses, her animal family also includes three cats named, “Billy,” “Bonnie,” and “Clyde,” plus a Belgian Malinois named “Boise” and a Blue Heeler named “Bear” On her rare days off, she enjoys hiking with her dogs.

Meet Maurice and Jelly Bean! 🫏❤️

At just 16 hours old, Maurice, an adorable miniature donkey c**t, arrived at Steinbeck Peninsula Equine Clinics with failure of passive transfer, severe hypoglycemia (low blood sugar), and moderate dehydration.

Maurice required around-the-clock neonatal intensive care, including IV fluids, continuous glucose supplementation, a plasma transfusion, feeding through a nasogastric tube, IV antibiotics, heat support, and extensive monitoring.

Dr. Laramie Winfield, Dr. Pricilla Brown, Dr. Brooke Spieker, Dr. George Kuesis, Eli Olind, RVT, and veterinary assistant McKenzie Bishop worked closely with Maurice throughout his hospitalization, with many other members of the Steinbeck team lending a hand in his care.

Why is failure of passive transfer important? 🍼
* Newborn foals rely on their mother’s first milk (colostrum) for antibodies that protect them from infection.
* If they don’t receive enough antibodies, they are at increased risk for serious, potentially life-threatening infections.
* Every newborn foal should have a veterinary examination and an IgG blood test between 12 and 24 hours of age to ensure they received adequate antibodies.
* Early detection and treatment can be lifesaving!

Maurice’s case is a reminder of just how quickly newborn foals can become critically ill and how important early veterinary care and a dedicated team can be for these tiny patients! ❤️

DOES YOUR HORSE HAVE CUSHING'S?

Pituitary pars intermedia dysfunction (PPID), formerly known as equine Cushing’s disease, is a progressive neurodegenerative disorder in horses. This means the pituitary gland can’t keep bodily functions in a healthy working state, resulting in a variety of clinical signs. PPID is also associated with several serious conditions, including laminitis, secondary infections and insulin dysregulation.

You’ll find a checklist of PPID dysfunction signs at:

IT’S TIME ••• 🍁••• TO IMMUNIZE!

We suggest administering fall immunizations in advance of cool weather. In the fall, we typically recommend vaccinating for Flu/Rhino and Rabies, but please talk with your veterinarian about which vaccines are appropriate for your horse at this time. It’s also a great time for f***l egg counts and deworming, which are required by most colic insurance programs. When we vaccinate your horse, we also do a brief, complimentary physical and oral exam.

Ask us about our SPECIAL BUNDLE PRICING for a blood panel and f***l egg count with fall vaccines.

SET UP A FALL VACCINE CLINIC AT YOUR BARN AND SAVE EVEN MORE!

Steinbeck Peninsula Equine Clinics’ own Dr. Lauren Winfield, and her husband Travis Mahoney, APF (Accredited Professional Farrier), have been breeding Dutch Warmbloods since 2020, when they launched MW Sporthorses, LLC. (MW is for “Mahoney” and “Winfield”).

Lauren got the ball rolling in 2013, when she acquired Coco Chanel, who became the dam and granddam of most of the MW foals to follow. Kalifornia Girl, Coco Chanel’s first foal, went on to become an accomplished Prix St. George contender.

Since MW began to produce foals, several have been presented at the Hanford KWPN inspection (known as a keuring), a prestigious annual horse evaluation event hosted at DG Bar Ranch in Hanford, CA. Organized by the KWPN-NA (Royal Dutch Sport Horse registry in North America), Hanford is one of the premier North American stops. Official inspectors travel from the Netherlands to grade the horses in several classes, both in-hand and under saddle. Foals & Young Horses are evaluated in-hand based on their conformation and movement. Learn more at https://kwpn-na.org.

This year’s MW foals include:

⭐️ Warden MW out of Nyx MW by Cum Laude, born in March, achieved a 2nd Premium (in the top 6-40%) rating, which is very respectable for a c**t that will likely go on to become more Jumper than Dressage horse.

⭐️ Winston MW was born in April. When his dam Essina was having health issues, Lauren’s sister, Steinbeck Peninsula Equine Clinic Director of Internal Medicine Dr. Laramie Winfield and the whole staff helped make the foaling process safe and effortless. While he was not shown at Hanford this year, he will likely become a solid Eventer, with half Show Jumper and half Dressage lines.

⭐️ Wonder Woman MW, resulting from an embryo transfer from Coco Chanel by Velantis, was born near the end of April. She achieved a coveted 1st Premium rating (top 5%) at Hanford!

⭐️ Wayland MW, born July 1st, out of Coco Chanel by Kaiman, also achieved 1st Premium, scoring exceptionally high marks for movement.
