I got a sad call from a new client yesterday. She said her dog was showing signs of dog-dog aggression and, from the advice of someone in the dog park, she hired a trainer that uses choke chains. She said initially the training wasn't too physical, but she ended up firing him because of his increasingly abusive techniques when dogs were around her dog.
While working with a private client on Wednesday, we ran into another local Chicago trainer. It was interesting, because we were both teaching our clients the exact same lesson, using different philosophies. The goal was to have our dogs meet each other calmly. My client and I were walking a 2 year old wheaton terrier, and the other trainer and his client each had a dog that they were working with. I used one of many strategies to get Misty to greet nicely.
