My last dog sweater thread derailment for now. I just finished the Arc'Teryx. It was a women's small that had been washed too many times. I kept the collar, used the fabric from the middle part of the back, sewed on an inner front pocket, and attached the hang tag.

Thanks for all of the compliments. These sweaters are actually fairly easy to make though. My sewing experience is limited to sewing 5 dog sweaters.
Dog could carry its own poop-bags and whatnot in that pocket. Genius.
