Axl, Jacks is a goldendoodle and he is great, but strong willed. I personally love goldens as I had two that were great dogs. However, as you spoke of GSs, purebreds have their health issues. My first golden had epilepsy from about nine months.
I had two Lab Shep. mixes that were very good dogs and extremely healthy. I think my yellow Lab Shep. was around 120 lbs and the second best dog I ever lived with after I got him over his separation anxiety. I came home one day when he was around a year old. He had toilet paper all over the house, ripped up a bath towel and chewed up a tube of toothpaste all over the living room (that was a mess to clean up.
I went to Home Depot, bought 2x4s, 2 sheets of plywood and hinges. I built a giant cage in the basement and whenever we left I took him to the basement and made it his home. After a year or so I called him to go in the cage, he followed me down, but then sat down when I told him to get in his cage. He just looked at me with those big brown eyes. I told him, okay, but he better be good and no damage. He never was a problem again.
