My dog runs away from his trainer?

I have a 2 year old husky labrador. About 3 months ago, he bit 2 people who were jogging by the house. After the incident, I call in a dog behaviorist. The trainer said that he has a program where he will hike with my dog and his pack of dogs and that will teach my dog to learn how to behave in a pack. At the same time he will teach us what my family and I have to do around my dog. The trainer picks my dog 3 times a week from my house but I noticed that Everytime he comes in, my dog runs away from the trainer... Is that a bad sign?
