 I don't care how old the dog is. They can be trained at 20 years old as far as I'm concerned. And then little by little, if you expose him to small dogs from a distance at first and every single time it's a positive relationship, little by little he will come around. Because if you associate small dogs now with positive things, what we call counter conditioning, he will come around. Now, I remember years ago I had to pull a couple of dogs from a really horrific, horrific dog fighting ring on Long Island where I lived at the time.
