I am trying to decide between group training classes or private training sessions for Trixie. I am concerned about her being around much larger puppies/dogs with owners who may or may not be watching them carefully. She also has not gotten her bordatella shot...and I was planning on not giving it to her. The trainer said it was important for Trixie to meet other dogs and people to socialize her. Now I don't know what to do - private or group. Anyone have any thoughts????
