We now have had Toby "temperment tested" by a dog behaviorist. It turns out Toby has developed "fear-based aggression" towards certain dogs. We are going to try and "recondition" him through positive behavior modification and see if he can change his attitude. The process is to keep him away from bad situations but also, in a controlled situation, introduce him to different new dogs from a comfortable distance and reward him for staying calm. The dogs gradually get closer but not too close to freak out. Eventually they do interact and hopefully all is well. We will see how it goes. I am skeptical.
My point was just that I think Toby ended up this way because of his habitual "in your face" approach. Too many other dogs got freaked by it and acted aggressively towards him. It is sad because last summer he was in love with every dog he met and even occasionally went to doggy daycare. Now we have to keep him on leash and away from kennels, daycares and unknown dogs.
Another possible cause of Toby's fear-based aggression is lousy breeding. We got him from a do-it-yourselfer and he is from her first litter. Now she refuses to consider the possibility that Toby's temperment problem may be genetic and that she should follow up and investigate her dogs. Others have complained of temperment problems from this breeder. She now will not return my emails because I suggested she might kick in for the behavior training. Live and learn.
