Started SAR training with Taz about a month ago, the group I am training with thinks he is doing amazing for his age. Taz is not super excited over anything like toys. I have bought every toy that people on this site says their dog love, and nothing. The group tells me he has to be working for something or will get bored and not want to search, they don't want me to use treats of food for reward. I am at a loss for what to do, I have just been praising him like crazy when he makes a find. Anyone have any suggestions.
