With so many canine and feline flea and tick products on the market, you practically need a course to help you decide which one to use. According to Ronald Baynes, DVM, PhD, an associate professor of pharmacology at North Carolina State University College of Veterinary Medicine, knowing the mechanism of action is key to sorting things out. Organophosphates and carbamates (kills and repels fleas and ticks) Among the first class of products used on pets was the organophosphate and carbamate insecticides used in foggers, dips, and sprays. These anticholinesterase insecticides work by inhibiting acetylcholine esterase, the enzyme responsible for breaking down the neurotransmitter acetylcholine at

Madison, Wisconsin, April 25, 2009. It’s a quiet, gray day outside in Madison, Wisconsin, but inside, the room’s abuzz. Fifteen dogs of various sizes are being handled by veterinarians and veterinary students in the Happy Pets, Happy Vets behavior and low stress handling workshop. The workshop, organized by the Behavior Club at the School of Veterinary Medicine, University of Wisconsin is my first symposium in Wisconsin. The event, consisting of a full-day lecture and half-day lab is so popular that it has to be held at a larger venue, an off-sight hotel. And a number of lecture participants are wait-listed

Chicken number one climbs up the ladder onto a one-foot-wide platform, makes a 180-degree turn and tightropes across a narrow bridge to a second platform, where it pecks a tethered ping-pong ball, sending the ball in an arc around its post.

It knocks the yellow one down first and then the blue one. Chicken number two grasps a loop tied

“The client, an elderly couple, had a 6-year-old male, neutered Rhodesian Ridgeback that was aggressive to dogs” describes Dr. Jennie Jamtgaard, an applied animal behavior consultant and behavior instructor at Colorado State University College of Veterinary Medicine. “They had watched Dog Whisperer with Cesar Millan and seen Millan place aggressive dogs in with his group of dogs and then hold them down on their sides or back if they were aggressive. So they brought their dog to the dog park and basically flooded him [immersed him in the aggression-inducing situation].” Not surprisingly, they didn’t get far. “The female owner was trying

On an episode of “It’s Me or the Dog,” a show on Animal Planet, British dog trainer Victoria Stilwell tackled the problem of a bull terrier that exhibited mounting behavior. The first solution was to send the dog for a time-out when he mounted. However, the mounting was so severe that the trainer finally recommended neutering, which solved the problem. This case raises two questions: What other behavioral issues can neutering help address, and what is the rate of success? In general, it would be expected that spaying or neutering most likely affects sexually dimorphic behaviors — those that are
