We have an 8 month old Golden- Seamus. He is our second. We lost our first golden to cancer about 4 years ago, and we lost our dear black lab in August. Seamus joined us in June, to accompany our coon hound Lilly (in other words, we have lots of dogs!). Goldens CAN and SHOULD be crated. We have a golden sized crate, and got a barrier wall to put in when the dogs were puppies. We have one crate in the family room and another in our bedroom- Goldens are people dogs and really, really need to be with people. Now that we are back to school (my DH and I are profs, and we have 4 kids), Seamus spends about 5 hours a day in the crate, and then some nights (when he is overactive or we can't watch him).
The "golden" rule about goldens- if you aren't watching the dog closely, s/he needs to be in the crate! Goldens chew, find trouble (they are experts), and have potty accidents. The crate prevents many, many problems. Put a toy or two in and they are quite content for a little while. It also makes a great time out place (effective for both you and the dog!).
Puppies need to be let out very frequently- at least every 1/2 hour. Eventually you will find the pup gives you "signs" s/he needs to go out- learn these. However, until you are 100% sure that s/he is trained- don't get lulled into complacency- when you can go 1 week with absolutely NO accidents, s/he isn't trained (and this can take a year!). Use the crate if you aren't watching. Exercise also helps (a tired dog is a dog too tired to find trouble!).
That being said, Seamus is a very, very important part of our life- along with dear Lilly Puppy. He is sitting at my feet as I type. We haven't put the tree up yet- and when we do it won't have any decorations on the lower half because of "tail damage". We have chew marks on some chairs in the kitchen and on the family room coffee table, but we view those as "love marks"- we can tell you which dog did which "bite". We still cry for Butchie and Merry Puppy when we accidentally call the wrong dog name. Dogs are a critical part of our life (and our cats and horses, too!). Goldens are special creatures- they know when you are happy and sad and can be the silliest beings on this earth. They may not be smartest, but they are loyal and trustworthy through and through.
A great website and discussion group for goldens is:

Good luck- be ready to fall completely and absolutely in love!
