My son wants a Border Collie.
My wife is reluctant because they have a reputation for getting bored easily and wreaking havoc.
At this stage we are probably going to get a Golden Retriever.
My first dog was a lab, from when I was one year old. Then when I was in my late teens my sister got a German Shepherd. They were both excellent dogs. I had a Golden Retriever for a year when I was in my thirties, he was a guide dog puppy and I had to give him back. Golden Retrievers have an excellent temperament and are very easy to train. But they really don't like the heat. When he was a small puppy I took him for a relatively short walk on a hot day and I had to literally carry him home when he collapsed on the ground panting.
