Fall deworming, teeth, and hauling: what do people actually do?

Whether to fecal-egg-count before the fall deworming, when the teeth check should happen relative to winter hay, and what changes for a horse who gets ulcer-y when he travels.

This is general information, not veterinary advice. Every horse is different. Talk to your vet before changing a feed, health, or care program -- especially for a senior, a hard keeper, or a horse with a known condition.
The short answer

All three are vet conversations rather than product decisions. In broad terms: fecal egg counts have largely replaced blind rotational deworming, teeth are best checked before winter hay rather than after, and travel-related ulcers are managed with a vet's diagnosis rather than an over-the-counter guess.

These are the three autumn questions where the right answer is usually "ask your vet, then act," rather than "buy this." We stock what you'll need for all three -- but on parasites in particular, what you give should follow what a test tells you, not a calendar.

Parasites

Fecal egg count before the fall deworming, or stick with the rotation my vet set up years ago?

Worth revisiting with your vet. Veterinary guidance has moved decisively toward testing first and treating based on results, because blind rotational deworming drives resistance and most horses turn out to be low shedders who need far less than the old calendar assumed.

A programme designed years ago may predate that shift. That's a reasonable thing to raise at your next visit rather than a reason to change anything on your own.

Once you know what you're treating, the active ingredient is what matters, not the brand. Ivermectin and moxidectin products target different stages and species than the fenbendazole and pyrantel ones, and a fall treatment often includes a tapeworm component -- which is what Zimecterin Gold and similar combination products are for. Your vet will tell you which class your horse needs.

Weight matters as much as product. Underdosing is one of the ways resistance builds, so use a weight tape rather than a guess before you set the syringe.

Teeth

Fall teeth check -- before winter hay or after?

Before. A horse moving from grass onto a hay-based winter ration is being asked to chew a lot more long-stem forage, and dental problems show up as dropped feed, weight loss, and poor condition exactly when the weather is hardest. Getting it done in autumn heads that off.

It also lines up neatly with the condition tracking worth starting now -- teeth are one of the first things to rule out when a horse starts losing weight.

How often a horse needs checking varies with age and history. Your vet or equine dentist will tell you what interval suits yours.

Travel

Fall show season means hauling again. What changes for a horse who gets ulcer-y when he travels?

Two things: manage the forage, and consider omeprazole around the trip. UlcerGard is available over the counter and is labelled for preventing gastric ulcers during stressful stretches like hauling and showing. Keeping hay in front of the horse before, during, and after travel does the rest.

The distinction worth knowing: UlcerGard is the over-the-counter preventive, given around a known stressor. GastroGard, the prescription version, is for treating ulcers a horse already has. If you suspect existing ulcers, that's a scope and a vet conversation, because symptoms alone don't tell you what's there or how bad it is.

An empty stomach on a moving trailer is the part you control for free. Hay in transit, and turnout rather than stall confinement at the other end, are the usual adjustments. Digestive support supplements are worth a look for horses who travel often, alongside the forage rather than instead of it.

If you're competing, check the current medication rules for your discipline and association before giving anything, including over-the-counter products.
