Big things ahead for Molly!

After being such a valued part of our team, Molly is officially heading to vet school and we couldn’t be more excited for her. Her last day with us will be April 24, and while we’ll definitely miss her around here, we’re proud to see her take this next step in her journey in equine medicine.

Molly, thank you for your hard work, your care for our horses, and the way you’ve shown up for this team. You’ve got a bright future ahead, and we can’t wait to see all you accomplish. 👏

Help us wish her luck in the comments! 💙

📣 EHV-1 Neuropathogenic/EHM Update—The following is directly from the Arizona state veterinarian. As always, we’ll update again if new travel requirements are released.

“The AZDA was notified by the attending veterinarian Wednesday night that two horses from Pinal county displaying neurologic signs tested positive with point of care EHV-1 tests on samples collected that evening. On Thursday, AZDA began reaching out to event organizers requesting information of attendees / registrants or contact info for messaging. On Friday 1/30/2026, one of the two hospitalized horses was humanely euthanized due to progressive neurologic deterioration. Confirmation of EHV-1 (neuropathogenic) by the reference lab was reported Friday afternoon. The events where exposure to the affected horse(s) or dangerous contact (exposed) horses of the affected horses (ie. other horses from the premises of origin of the two clinical horses) are as follows:

January 18, 2026 – Horseshoe Park Extreme Barrel Race
January 20, 2026 – ICE Wittmann Breakaway Roping
January 21, 2026 – Roper Nation Breakaway Roping
January 21, 2026 – John Volken Academy Ranch
January 23, 2026 – TACC Thunderbird Farms Arena
January 24, 2026 - Horseshoe Park Extreme Barrel Race
January 27, 2026 – TACC Thunderbird Farms Arena

As always, many horses even in a normal population may be completely asymptomatic intermittently shedding herpes virus and a smaller subset of those will be shedding neurotrophic herpes (and still may be asymptomatic). Given the extensive show history that has already occurred it's difficult to be on the leading edge of this like the horses returning to Arizona from the Waco, TX and Guthrie, OK events at the end of November where quarantine of returning horses was more feasible. In the current situation the best course of action for your clientele if they have had horses at these historical events would be to encourage re**al temperature monitoring twice daily with logging the results to chart trends, prompt reporting of any signs consistent with EHV-1 (respiratory or neuro) infection to their attending veterinarian and testing (nasal swab and whole blood PCR) if indicated, and voluntary self-quarantine from attending any new shows for the next 14 days.”

Mosquito season starts in 6 weeks. Is your horse protected? 🦟

Arizona mosquitoes arrive in March carrying West Nile Virus and Sleeping Sickness. Vaccines take 2-3 weeks to work, which means you need to schedule NOW.

What's due:
- West Nile Virus

Not all lameness is obvious. Here's what to watch for 👆

Lameness is any abnormality in a horse's gait caused by pain or mechanical dysfunction. Sometimes it's obvious (non-weight bearing), but often it's subtle.

Subtle signs:
- Head bobbing at the trot
- Shortened stride on one leg
- Resistance to bend one direction
- Difficulty with upward transitions
- Uneven landing or push-off

Common causes:
- Hoof issues (abscesses, bruising, thrush)
- Joint problems (arthritis, inflammation)
- Soft tissue injuries (tendons, ligaments)
- Improper shoeing or trimming

When to call us:
- Non-weight bearing lameness (emergency)
- Lameness lasting more than 24 hours
- Lameness with swelling, heat, or sensitivity
- Any sudden change in gait

We have advanced diagnostics available including standing MRI, nuclear scintigraphy, and digital radiography to pinpoint the source.

Early detection = better outcomes.

Arizona pastures need management year-round, including winter 🌾

Desert and semi-arid pastures don't recover like those in wetter climates. Winter grazing requires attention to prevent overgrazing and maintain horse health.

What to watch:
- Overgrazing - Desert plants recover slowly. Bare dirt = erosion and dust
- Rotation - If possible, rotate pastures to allow regrowth
- Supplemental hay - When grass is sparse, horses need additional forage
- Toxic plants - Winter weeds can include harmful species (check with extension office)
- Body condition - Horses on sparse pasture may lose weight quietly

Arizona-specific concerns:
- Dust from overgrazed pastures can cause respiratory issues
- Minimal winter rain means slow pasture recovery
- Some desert plants are more palatable (and toxic) in cooler months

If you're unsure about your horse's nutrition on pasture, we can help assess body condition and recommend appropriate supplementation.
