And, I also agree with the previous posters... she sounds extremely bored and under-stimulated. Give her lots of walks every day (at least 1 or 2), exercise her in the backyard twice a day until she is tired, teach her new tricks, give her stuffed Kongs and treat balls, etc. You can't just leave her in the house or backyard and expect her to lay around and be happy. She is a young, HIGH energy dog!! One of the misconceptions people have about Golden Retriever (and Labs) is that they are lazy, trustworthy, gentle dogs their entire lives. They're actually a sporting breed, very very high energy and intellegent and they NEED outlets to put all of that energy into.
