Well, I didn't finish the book, but I certainly reached 50,000 words (50, 937 according to the word count validator, though Open Office says 52, 037. That's a disappointing discrepancy). And ordered the t-shirt.
This was an interesting novel to (mostly) write. I outlined most of it, for one, though there was a point at which the outline didn't matter anymore. I made some changes in the actual writing of the novel, which made some things make more sense, and made the outline eventually obsolete.
My interest in dogs has quite permeated my writing, depending on the topic. Considering this is a werewolf series (well, duology currently. I'd like to make it a trilogy, I think), I made an effort to use canine body language, even when the characters were acting as humans rather than canids. It made sense in the context, and was interesting to think about. What does angry look like? Interest? Nervousness? It's interesting to compare these things to human body language as well; have you watched the show Lie To Me? You should.
