I just adopted a six month old terrier mix last month. He isn't my first dog, by the way, I have had probably a dozen since childhood.

Anyway, I've been trying to socialize him and I've been working on his relationship with my husband and my son. I've been taking him on walks, which is hard because he lunges and snaps and barks at everything that moves. He also chases after cats.

For the first three weeks, all was great at home. My son and I shared the doggy duties (feeding, treats, playtime, walks, training) while my husband was at work. Two days ago, however, he tried to bite my son while my son was giving him treats. He just lunged at his face and bit; lucky my son moved away very quickly. He didn't show any stressful signals or body posture, no growl, etc. A few hours later, he did it again. My son is eight and a great kid. I'm a housewife and I have eyes like a hawk so I would know if he ever did anything to my dog, plus they're never left together alone.

Now my dog has taken to growling, barking, and/or adopting an aggressive pose (teeth bared, stare, etc) whenever my son walks into the room and tries to lunge at him. I've tried distracting him by having my son throw treats, throwing treats myself, pet names, etc. It works SOME of the time. Other times I have to pick my dog up and just leave the room for a bit.

I'm really lost right now and I'm not sure what to do to fix this. I don't want to do any dominance-based training because I think that will do more harm than good. What positive approach should I take to get my dog to like/trust my son more? He's going to start sessions with a trainer/animal behaviorist in a couple of weeks but until then, what precautions should I take?

Thanks so much in advance!

Hi, I know you don't want to use the dominance based training but sometimes reward based training just isn't enough. Its great that he will be seeing a behaviorist in the near future. For your sons safety you probably want to keep them separated until you see the behaviorist. Do not pick the dog up when your son walks into the room, that is the worst thing you can do! Put a lead on the dog and walk him out. To many people pick there small dogs up when they show aggression but this will feul his aggression. Don't let him on the sofa or in the bedrooms. He obviously rules the house and you!

Reward based training works great for training, but your dog needs rehabilitating so don't rule out the pack theory all together. Also, make sure you find a good behaviorist. I've known many people that have paid lots of money to be told what they already know and haven't actually dealt with the issue. Good luck!
