Friesian horses far more susceptible to genetic defect associated with painful eye condition - An interdisciplinary team of scientists and clinicians, led by Dr. Rebecca Bellone at the University of California Davis Veterinary Genetics Laboratory, has identified a genetic variant associated with distichiasis in Friesian horses.

There are two simple words that describe painful, exercise-associated muscle cramping in a horse: tying up. While the traditional tying up usually occurs after a long hard ride, some horses can tie up repeatedly for no immediately obvious reason. Regardless of the underlying cause, the clinical signs are similar. And in most cases, affected horses require immediate veterinary care, says Dr. Fabienne Uehlinger of the Western College of Veterinary Medicine (WCVM) in Saskatoon, Saskatchewan.

There are a vast number of plants located throughout Canada that are toxic to horses in some respect. Many need to be eaten in large doses to cause much of an effect, while others require only a few mouthfuls. There are a variety of resources on plants toxic to livestock, but the Canadian Poisonous Plants Information System seems to be the most comprehensive. It lists over 250 poisonous plants found in Canada, their lethal dose (if known), and symptoms of poisoning.
