โ€œTo be a good equine vet you have to have patience and dedication, and you have to be passionate about what you do. It takes staying up all night and getting up the next day to do it all over again. I hope when someone talks about me they say that I try as hard as I can every day.โ€ - Dr. Don Lee, DVM

We only do this a couple times a year, so now is your chance. What topics do you want us to cover? What questions do you have? Lameness, injections, ulcers, feeding, supplements, young horses, maintenance, small animal questions, or something you have always wondered but never asked.

Drop your questions in the comments and we will start breaking them down in future posts. No question is too small and if you are thinking it, chances are someone else is too.

Hereโ€™s to a new year of sound horses, healthy pets, and good conversations. Happy New Year from all of us at Double X.

A horse can look sound on one surface and sore on another. Footing plays a huge role in how joints, tendons, ligaments, and feet are stressed. Hard ground increases concussion, deep ground increases strain, and inconsistent footing forces the horse to compensate.

When a horse feels off only at certain arenas or events, footing should always be part of the conversation. It helps explain intermittent soreness, inconsistent performance, and why a horse may feel great at home but struggle elsewhere.

Soundness is not just about the horse. It is also about what they are asked to work on.

Gastric ulcers are extremely common and affect far more than just high level performance horses. Any horse can develop ulcers, including pasture horses, broodmares, and young horses in training.

A horseโ€™s stomach produces acid continuously. In natural grazing situations, constant forage helps buffer that acid. Stress, hauling, stall time, fasting, and high grain diets all increase ulcer risk by allowing acid to damage the stomach lining.

Signs are often subtle and easy to miss. Poor appetite, girthiness, attitude changes, performance decline, weight loss, or intermittent colic can all point toward ulcers. Some horses show no obvious signs at all.

Gastroscopy is the only definitive way to diagnose ulcers and determine severity. Treatment usually involves acid suppression medications paired with management changes like increased forage, reduced grain, and minimizing stress.

Ulcers are very manageable when caught early. If your horse feels off and lameness has been ruled out, the stomach should always be considered.

Some horses limp at the smallest discomfort. Others keep running like nothing is wrong until the issue is significant. Pain tolerance, temperament, adrenaline, and training all play a role in how a horse shows soreness.

That is why performance history, subtle changes, and rider feel matter just as much as what we see on a jog. A horse that feels different but does not look lame is still telling you something.

Flexion tests are a common part of a lameness exam, but they are often misunderstood. A flexion test does not diagnose a specific injury. It helps localize discomfort and tells us where to look next.

During a flexion test, a joint or group of joints is held in a flexed position for a short period of time and then the horse is immediately trotted off. If the horse shows increased lameness afterward, it suggests that area may be sore or under stress.

A positive flexion test does not automatically mean a horse needs injections or time off. Many factors influence results including footing, fitness, conformation, age, and how the test is performed. Flexions are just one piece of the puzzle and are always interpreted alongside gait evaluation, palpation, imaging, and performance history.

When used correctly, flexion tests help guide diagnostics and treatment instead of guessing. They are a screening tool, not a final answer.

Twas the night before Christmas and all through the clinic
Not a creature was stirring except phones going ballistic.
The charts were all finished or so we all thought
Till a client called saying โ€œHeโ€™s just a little offโ€

The techs were exhausted, coffee cups dry
Wondering how many times someone would ask โ€œIs this normal?โ€ with wide eyes.
Don rubbed his temples, Olivia sighed
Another emergency that absolutely could not wait till sunrise.

The clients meant well, we promise itโ€™s true
But itโ€™s always after hours when something feels new.
โ€œHe was fine yesterdayโ€ is a phrase we all know
Usually right before a colic or a swollen hock shows.

Meanwhile at home horses stood snug in their stalls
After ignoring us all year they suddenly need calls.
Because Christmas Eve is the perfect time
For eye ulcers, abscesses, and mystery lameness combined.

But hereโ€™s the truth wrapped in sarcasm and cheer
We love our clients and your animals dearly, year after year.
We laugh, we stress, we run on caffeine and hope
And somehow together we manage to cope.

So from our vets, techs, and staff running on fumes
Thank you so much for trusting us with your petsand barnyard goons.
We wish you a Merry Christmas thatโ€™s quiet and bright,
With sound horses, healthy pets, and a peaceful good night!

Ponies are not just small horses. Their metabolism works differently, which means they are far more prone to issues like insulin resistance, laminitis, and weight related joint stress. A pony that looks โ€œeasy keepingโ€ can actually be at higher risk than a performance horse on a full feed program.

Managing ponies properly often means stricter diet control, limited lush pasture access, regular hoof care, and paying close attention to subtle changes in stance or movement. Catching problems early is the difference between long term soundness and chronic lameness.

Today we are talking about Minocycline, an antibiotic we keep on hand for specific cases where its spectrum works better than other options. Minocycline belongs to the tetracycline family and is commonly used in horses for infections involving joints, wounds, skin, and certain tick borne diseases. It is also used in some complicated or chronic infections when other antibiotics are not effective enough on their own.

This medication is chosen when we need strong tissue pe*******on, especially into bone and joint spaces. It is not a first line antibiotic for every situation, so it is always prescribed based on culture results, clinical signs, or the specific type of infection we are treating. Minocycline must be dosed correctly to avoid resistance and side effects, so it should never be used without veterinary guidance.

If you ever have questions about why a certain antibiotic was chosen for your horse, we are always happy to explain the reasoning and what to expect during treatment.
