We did 2 puppy class series when our pup was 4 months old. We learned the most effective way to train her and she was able to socialize with the other puppies. Classes were small and i private which we liked. Vania was an excellent trainer and our pup loved her. After the classes were over we used Vania for some private sessions. I am proud to say that our young one year old dog is now a certified therapy dog. We could not have done it without At Attention and Vania. I highly recommend them.
