Dr Dyck's Joke of the Week....
Those who know Dr Dyck are aware of his fondness for a good joke. So we thought we'd share a chuckle or two each week (semi-clean ones, of course)
A HUGE THANK YOU TO
JEFFERY HALL, DVM - ZOETIS EQUINE TECHNICAL SERVICES,
Sara Cash of Zoetis and
Erin Hebert of Henry Schein for sharing such wonderful info with our clients about how to protect our horses from diseases! It was a fun evening and we look forward to the next one! A special thanks to our clients for attending - we hope you enjoyed the presentation!

IN THE NEWS...We get a lot of calls and questions regarding EHV-1, so we thought we'd pass on the following article written by Dr Thomas R Lenz, DVM, MS that was shared via the AAEP:
Most horse owners know that the equine herpesvirus type 1 (Rhino) causes upper respiratory infection in young horses and abortion in pregnant mares, but many probably don't realize that it can also cause a severe neurological disease that affects the horse's brain and spinal cord and may result in paralysis and death.
EHV-1 routinely causes upper respiratory infection in young horses (weaning, yearlings, and 2 year olds) resulting in depression, a snotty nose, loss of appetite and persistent cough. If a number of young horses are housed or pastured together, most will become sick and the recover uneventfully. Pregnant mares that become infected often abort their foals late in gestation, deliver stillborn foals or weak foals that die within days of birth. In rare instances, adult horses experience the respiratory form of EHV-1 and then develop the neurological form of the disease called equine herpes myeloencephalopathy (EHM).
Neurological symptoms include incoordination that can progress to the inability to stand, lower leg swelling, the inability to urinate or pass manure, urine dribbling and reduced tail tone. Some of these symptoms also occur in other neurological diseases such as rabies, EPM and West Nile Virus infections, so it is important that the animals be examined by a veterinarian as soon as possible.
Because EHV-1 ia a virus, it does not respond to antibiotics. Therefore, supportive treatment is the only option and is tailored to the individual patient and guided by the severity and range of clinical signs. It usually includes anti-inflammatory drugs, fluids to maintain hydration, and slinging of horses that are unable to stand. In most cases, horses that remain standing have a good prognosis, although recovery may take weeks or months. Horses that go down and are unable to stand have a poor prognosis.
EHV-1 is spread primarily through coughing or sneezing, but can also be carried in fetal tissues, the placenta and uterine fluids from mares that have aborted. Studies have shown that the virus doesn't live long in the environment, but transmission via coughing or sneezing can occur over a distance of up to 35 feet. Direct contact with infected horses as well as contaminated feed, equipment, clothing, and tack can also spread the disease. The good news is that the virus is killed easily by disinfectants.
When treating an area where the disease has occurred, remove all organic material such as manure and dirt. Then disinfect all surfaces and equipment with a solution of 1 part bleach (sodium hypochlorite) and 10 parts water. Make sure you use rubber gloves when handling the disinfectant. Don't forget to wash and disinfect any trailer that has been used to transport sick animals.
Without a doubt, the biggest problem with EHV-1 is that once horses have been infected they can become latent carriers of the virus for the rest of their life. Although latently infected horses are no longer sick or shedding the virus, they carry the virus and can spontaneously begin shedding it during periods of stress. The intermittent shedding by carrier horses is thought to be the source of sporadic outbreaks of the disease, including closed herds where no new horses have been introduced. Elimination of EHV-1 from a herd is virtually impossible because of the presence of latently infected animals. However, a good strategy to reduce the incidence of EHV-1 is the combination of a good vaccination program in conjunction with the implementation of an effective preventive herd- management program.
Vaccination schedules vary based on the region of the country, the age of the animals, and the type of work they do for a living, so visit with your local equine veterinarian to get their recommendations for your specific horses. In addition to an aggressive vaccination program, new arrivals, sick horses, and horses returning from shows or other horse facilities should be isolated for at least seven days. If horses at the show were sick or there was a confirmed EHV-1 outbreak, isolate the horses for 21 days. Disinfect all areas of the barn in which a suspect or sick horse has been housed or worked.
If an outbreak of the disease occurs in your area, encourage the barn personnel and riders to wear leather or rubber boots that can be disinfected in a disinfectant tub at the entrance of the barn. Segregate horses into the smallest possible groups. Large groups of horses sharing a common airspace can all be infected by one horse shedding the virus. And finally, if you suspect that your horses have been exposed to the EHV-1 or equine influenza virus, take rectal temperatures daily (normal adult body temperature is 100.5 F). If any horse's body temperature is elevated, consult your veterinarian immediately. The neurological form of the disease usually appears 7-14 days after the horse starts running a fever.
