🐴✨ Managing Lameness & Joint Health in Horses: What Are Your Options? ✨🐴
When battling lameness issues, horse owners are often faced with many therapy and medication choices. With so many products on the market, it can feel overwhelming to decide what’s best for your horse. Let’s break down some of the most common options and when they’re most appropriate.
Prescription Joint Therapies:
🟢 Adequan (polysulfated glycosaminoglycan, PSGAG)
• ✅ FDA-approved for degenerative joint disease in horses
• 💉 Given as a series of intramuscular injections prescribed by your veterinarian
• Helps:
o Reduce inflammation
o Improve joint lubrication
o Stimulate cartilage repair
Adequan works on the joint at a cellular level, helping protect cartilage and support long-term joint health.
🔵 Legend (hyaluronate sodium)
• ✅ FDA-approved for degenerative joint disease in horses
• 💉 Administered as a series of intravenous injections prescribed by your veterinarian
• Helps:
o Reduce inflammation
o Improve joint lubrication
Legend primarily supports the synovial fluid (joint fluid), helping joints move more smoothly and comfortably.

Joint Supplements:
Unlike Adequan and Legend, joint supplements are not FDA-approved medications. They are designed to support joint health and help minimize wear and tear over time.
🔎 Common ingredients to look for:
• Glucosamine
• Chondroitin sulfate
• MSM
• Hyaluronic acid
While these ingredients can provide continuous support, absorption can vary within the complex equine digestive tract. We recommend choosing products backed by solid scientific research and veterinary guidance.

🕒 When Should Each Be Used?
Adequan & Legend
Commonly used once joint trauma or osteoarthritis has already developed. Can also be used as a preventative measure to maintain joint health and delay need for synovial injections.
These medications are excellent options when:
• Synovial (joint) injections are not required
• Synovial injections are contraindicated
• Systemic joint support is needed
After the initial loading series, maintenance doses can be customized to your horse’s needs.

Joint Supplements
Most effective:
• Early in the disease process
• Before signs of joint dysfunction appear
• As part of a preventive or maintenance program
Think of supplements as a daily vitamin for joint maintenance, not a standalone treatment for advanced joint disease.

Every Horse Is Different
Choosing the right product depends on:
• Age
• Discipline and workload
• Severity of joint changes
• Overall health status
A veterinary exam and proper diagnosis are essential before starting any joint therapy.

🌟 Show season is around the corner! Now is the perfect time to evaluate your horse’s joint health and create a proactive plan.
If you think your horse could benefit from joint support, consult your veterinarian to determine the best option for their individual needs.
At GGEH, we’re here to help your horses feel and perform their very best this season! 🐴💚

🐴 Your Mare Is Pregnant—Now What? Vet-Recommended Steps to Follow 💙
A healthy pregnancy starts with good planning and routine veterinary care. Here’s a simple timeline to follow:
Early Pregnancy (14–30 days):
✔️ Pregnancy confirmation by ultrasound
✔️ Check for twins (and manage early if needed)
Early Pregnancy Follow-Up (≈45 days):
✔️ Ultrasound recheck at ~45 days to confirm a viable pregnancy
Early–Mid Pregnancy (3, 5, 7 & 9 months):
💉 Vaccinations at 3, 5, 7 and 9 months (Rhinopneumonitis vaccine based on risk factors of each mare)
✔️ Maintain good nutrition & body condition
✔️ Routine farrier and dental care
✔️ Normal exercise unless advised otherwise
Mid-Pregnancy (≈5 months):
✔️ Re**al palpation around 5 months to monitor uterine health and pregnancy progression
Late Pregnancy (last 3 months):
✔️ Increase nutrition as fetal growth accelerates
✔️ Pre-foaling vaccines 4–6 weeks before due date
✔️ Deworming per your vet’s recommendations
✔️ Prepare foaling area and foaling kit
🚨 Always watch for:
• Vaginal discharge
• Premature udder development
• Colic signs or sudden behavior changes
Routine checkups throughout pregnancy help catch problems early and support a healthy mare and foal. If your mare is bred or confirmed pregnant, we can help create a plan tailored just for her. 🐎✨

🐴 Thinking about breeding your mare? Start with these vet-approved steps:
1️⃣ Pre-breeding exam – A full reproductive check (uterus, ovaries, cervix) to be sure she’s a good candidate. We may suggest other testing based on her history or findings on examination.
2️⃣ Health basics – Up-to-date vaccines, deworming, good body condition, and sound overall health.
3️⃣ Choose the right stallion – Consider temperament, conformation, performance, and genetic compatibility. Share your breeding contract with your veterinarian for planning purposes.
4️⃣ Timing is everything – Ultrasound and heat detection help us breed at the right moment.
5️⃣ Breeding method – Live cover, shipped semen, or frozen semen—each needs a different plan.
6️⃣ Post-breeding care – Pregnancy check starting at ~14 days to keep things on track.
Breeding isn’t just putting a mare and stallion together—it’s planning, timing, and good veterinary care. If you’re considering it this season, talk to your equine vet early so we can set your mare up for success. 💙🐎

🐴 Senior Horse Sunday: Cushing’s Disease (PPID) 🐴

Cushing’s disease—also known as Pituitary Pars Intermedia Dysfunction (PPID)—is a common condition in older horses. It’s caused by a benign tumor of the pituitary gland, leading to overproduction of hormones (especially ACTH) that can affect multiple body systems.

🔍 Common Signs Owners May Notice:
• Long, curly hair coat or failure to shed
• Loss of topline or muscle
• Weight loss
• Laminitis/founder
• Increased drinking and urination
• Changes in sweating (patchy or none at all)
• Chronic or slow-healing infections (eye ulcers, hoof abscesses, rain rot)

🧪 How Is PPID Diagnosed?
• Baseline ACTH test: Most common screening tool (levels may naturally rise in fall)
• TRH Stimulation Test: More sensitive, especially for early disease
• Annual re-testing is recommended once treatment begins to ensure proper dosing

💊 Treatment Options:
• Prascend® (pergolide) is the FDA-approved treatment
• Typically given as 1 tablet daily (dose may vary by horse)
• Temporary decreased appetite may occur when starting—often resolved by gradually increasing the dose
• Less common side effects include lethargy or behavior changes
• Other medications exist but generally have lower to no effectiveness

🩺 Early diagnosis and proper management can greatly improve your senior horse’s comfort, health, and quality of life. If you notice any of these signs, please call us to discuss!

💙 Because our senior horses deserve extra care.

🐴 Foaling Time: What to Do When Your Mare Foals 🍼

Most mares do great on their own—but knowing what’s normal (and what’s not) is key.

The 1-2-3 Rule to remember:
⏱️ 1 hour – Foal should stand
🥛 2 hours – Foal should nurse
🧬 3 hours – Mare should pass the placenta (SAVE IT!)

Right after foaling:
✔️ Make sure the foal is breathing well
✔️ Dip the umbilical stump (using dilute iodine or dilute chlorhexidine solution)
✔️ Confirm nursing and good colostrum intake
✔️ Check the mare for excessive bleeding or discomfort

🚨 Call your vet immediately if:
• Labor lasts >20–30 minutes with no progress
• Red bag delivery (you should see a white amnion, nothing red!)
• Foal is weak, not standing, or not nursing
• Placenta isn’t passed by 3 hours
• Mare seems painful or unwell

A quick post-foaling exam and IgG test (~12-24 hours of age) can catch problems early and set both mare and foal up for success.

When in doubt—call your equine vet. We’d much rather say “everything looks great” than miss something important. 💙🐎

🪱 Parasite Control in Horses: A Smarter, Targeted Approach 🪱

Parasite control has evolved! We’ve moved away from rotational deworming (grabbing a different tube every couple of months) and toward a strategic, evidence-based plan that’s better for your horse and helps prevent parasite resistance.

✨ Why the change?

Most horses have strong natural immunity that keeps parasite levels low. We assess this immunity using a F***l Egg Count (FEC), which categorizes horses as low, moderate, or high shedders. From there, we tailor a deworming plan specific to your horse.

🔬 What is a F***l Egg Count (FEC)?

An FEC measures parasite eggs per gram (EPG) of manure and helps guide appropriate deworming—no unnecessary treatments.

📅 When should FECs be done?

• Annually to monitor immunity and check for resistance
• Timing matters! Some dewormers remain effective for up to 16 weeks, so please check with Green Glen if your horse was recently dewormed before submitting a sample.

💩 Sample requirements:

• ONE fresh manure nugget (no need for the whole pile!)
• Can be refrigerated for 1–2 days if needed, but fresh is best

🐎 How often should my horse be dewormed—and with what?

🔹 Low Shedders (500 EPG)
✔️ Four times yearly
• Early Spring: Ivermectin or Moxidectin
• Early Summer: Ivermectin
• Late Summer/Early Fall: Ivermectin
• Early/Late Winter: Ivermectin + Praziquantel
(or Moxidectin + Praziquantel)

⚠️ Important note on Moxidectin:

Moxidectin is a very strong dewormer and one of the few effective against encysted larvae. It should be used with caution in:
• Older horses
• Miniatures
• Donkeys
If encysted larvae are a concern and moxidectin is not ideal, an alternative is a double dose of fenbendazole for 5 consecutive days.

🧪 Concerned about dewormer resistance?

We can perform a F***l Egg Count Reduction Test (FECRT):
1️⃣ Submit a f***l sample
2️⃣ Deworm your horse
3️⃣ Submit a second sample 2 weeks later
A healthy response should show ≥80% reduction in egg count.

👶 Foals & Young Horses

YES—deworming is different
• Deworm at 3, 6, 9, and 12 months
o 3 and 6 months: Double-dose fenbendazole
o 9 months: Ivermectin
o 12 months: Ivermectin + Praziquantel
• After age 1, treat as a high shedder until ~3 years old
• FECs can be done earlier if concerns arise, though young horses often haven’t fully developed immunity yet

💚 Bottom line:
Targeted deworming = healthier horses, fewer drugs, and reduced parasite resistance.
