I don't have that book. The name of the particular pattern might help us to find a picture of the finished doggie sweater on Ravelry or somewhere.
I'd be happy to look at a few rows and see if I see an error or anything. I will not be able to get to it right away though because I'm involved in Vacation Bible School at my church every morning this week (in fact I need to get off this computer and finish my notes on what I'm going to say tomorrow
). If you put a few rows here maybe someone will get to your question before I can get to it.
