What a beautiful dog, she looks super smart too. If you'd like to keep her busy and really challenge her, there are some great puzzels for dogs on the market.
I read about some doggy puzzles made by Nina Ottosson in this article http://www.thebark.com/content/puzzles-dogs
They sell some of the puzzles on Amazon and a bunch of retail shops around the country. There's other brands of dog puzzles out there as well.
