I've been to many dog schools, but Greta is the very best. She is a perfect trainer. I didn't say dog trainer on purpose, because I've found out that the problem is usually not with the dogs, but with the owners who don't understand the dogs' signals like I do. Greta knows all the dogs' signals and translates them into a language that the owners can understand. You don't need a better trainer than her. I love it!
