It is wonderful to see someone decide that the breed that they think they love might be too much for them! So often we see people get the dog anyway and then a year later they are rationalizing and blaming someone else for a dog that is aggressive and obnoxious because they didn't do their homework or listen to the experts!
Those working dogs are a handful and not for the faint of heart.
Good luck on your search for an ethical breeder. Don't forget to do all of your homework as far as genetics issues and such!
