Crochet Dog

I'm still working on teaching myself how to crochet... and  I finally finished the Amigurumi crochet dog I was working on while we were vegging over the Christmas weekend.  I think he turned out kind of cute... 

While I was crocheting him though, I realised that I crochet between the two loops of the previous row instead of under both loops.   It still seems to work, but I wonder how differently the final product would turn out if I followed the instructions correctly?
