Food is always the same whether you or your trainer gives, while praise can vary from one person to the other. The key to training to food is to be consistant until the behavior conditions. In other words, do not stop using food for months if you have to. I got Cruiser from a Labrador Breeder out of Okeechobee, Florida. I made sure that both parents' hips were OFA Certified as well as an eye certification.
Labs can carry inherited eye problems.
I also wanted a pup from field lines for my purposes. The most common behavioral problems I work with are dogs jumping up on people. First, you have to understand why they do it. Dogs are pack animals. Due to are busy schedules we are separated from our dogs quite often.
