Here are basic screwworm recommendations for horses - this can include donkeys and mules as well. Make sure to check under fly sheets daily!! Please do NOT mass deworm your horses every week unless you have been advised to by your veterinarian! We don’t want to increase parasite resistance! Check out Dr. Shawn’s video for his cattle (and food animal) recommendations!

Dr. Shawn has some basic recommendations for our clients for New World Screwworm in cattle. If you are a client and have more specific questions for your cattle, please call our office and we’ll set up a phone consult with Dr. Shawn.

We can only set up phone consults (telemedicine) with current and established clients due to Texas Law. We appreciate your understanding!

Screwworm has been confirmed in Zavala County. The first priority for all our producers and clients should be monitoring all animals on a daily basis for any wounds. This includes newborn animals with an umbilicus. Call our office if you have any questions and especially if you find an animal with a wound and find maggots. Our office phone number is 830-780-2170.

On June 3, 2026, the Texas Animal Health Commission (TAHC) received confirmation of a detection of New World screwworm (NWS) in Zavala County, Texas. The best thing that livestock producers and animal owners can do to prevent infestation is to put eyes on their animals as often as possible, remain vigilant by implementing enhanced management practices to avoid creating wounds, and promptly report suspicious wounds.

Part 3/3 of castration tools. These are the main styles I use for horses (and the other vets use for other livestock). This video got longer as I wanted to explain so many things about the tools! Pardon my camera jitters when I explain how long to leave the crush on - you clamp for one minute for every year of age!

Part 2/3 Castration Tools. Banding techniques. Pro tip - use fresh bands every time, don’t use last year’s leftovers for this year’s calf crop! Also- tetanus vaccines!

The smoothest (and slowest!) recovery of a horse following field anesthesia. Beau read the textbook and followed the guideline!

The patting, sticking fingers in his nose, pulling on the lead rope are all ways to encourage him to get up when we can tell he’s just relaxed and choosing to sleep.

Some horses fight and stand too soon - we stay really quiet with those.

We wish all recoveries could go this smoothly!

Wolf teeth removal!! This is a common procedure to add on to castration surgeries.

This tooth sits just in front of cheek teeth and many trainers have felt they created a problem with the bit during training. It is likely not as problematic as previously thought (exception is BLIND wolf teeth) but many trainers still want them removed before starting training.

This tooth is nonfunctional for horses , it does not assist in chewing. So if removed properly, it does not cause any issues long term.

Wolf teeth are not the same as canine teeth! The canine teeth are closer to the front of the mouth and are easier to see.

Mainly only male horses have wolf teeth and canine teeth but we do occasionally find them in mares. **CORRECTION - wolf teeth are not more predominant in males, only canine teeth. Something that I have had a misconception on for several years! We’re always learning!**

Blind wolf teeth are when the tooth has not broken through the gum line. These can cause significant pain if any pressure is applied on the gum line because it’s pinching the gum between the tooth and the outside pressure.
