What is a stupid dog? If lz refers to a stupid dog who is not smart, then you are wrong. Golden retriever's IQ ranks high among dogs. Although it is not as good as border herding, it is still very humane, smart and has many training methods. If lz finds it troublesome, it is also a good choice to find a training institution. If you train by yourself, it's available online. I hope my answer can help you.
