I personally think that bringing your dog to work is the best part of having a Guide Dog puppy. This way they aren't kept at home for the whole day.
Eve spends her day with me in my cube. She has a nice big kennel, which she likes to sleep in. She also has plenty of toys, plus a stuffed dog to keep her company.
On the other hand, her kennel doesn't seem so big when there is a big dog in there. On Monday we swapped puppies so I had a big dog named Dickens ... he barely fit in the kennel, and he didn't like the blanket, so he scruntched it all up in the front for a pillow.
