<human>: Can you provide a brief rundown of the text in within 3 sentences?

So we adopted a new puppy on Friday and I've been working with him on potty training. He's getting alright at it but sometimes he doesn't want to go, so he just sits there whimpering and shivering. So we run back to the house because it's so cold outside and within 2-3 minutes of being inside he poops! I keep staying out there longer but it doesn't seem to help much. 

I just brought him out about an hour ago and he managed to poop and pee a little but I thought he was done. He came and sat next to me and was shivering so I figured he was done. Walking in the door I take off his leash, start taking off my jacket, and I see him squat to pee next to the chair. It's currently 14f out and it's freaking cold. In my fleece pants and wool jacket I'm cold, so I figure he must be even more cold. He was doing well this afternoon when it was in the higher 30's!
<bot>: Should I swing into Petco/Pet Smart and pick him up some booties and a jacket/hoodie to help?
