It is essential that your Golden gets at least an hour and half of exercise and stimulation a day, a Golden will not exercise itself! You need to be out there with them, throwing a toy to retrieve, running, playing tug and learning new games you can't just leave them in the yard by themselves they'll just sit longingly at the door begging to be let back in with their family. This is quite a commitment and something you need to be prepared for if your Golden doesn't get enough stimulation they will become bored and full of pent-up energy, leading to hyperactivity causing them to bounce around the house, barking and destructive chewing. This is not a golden being naughty, this is a completely natural release for bored dogs with no other outlet for their energy. Even if you do have enough time to look after a golden you will also need the energy, if you love being outdoors walking, swimming, hiking etc.. then a Golden sounds a perfect fit, however, if you prefer to stay at home watching the TV or don't like to go out when it's wet and cold then a Golden probably isn't right for you.
