I have a really warm coat and Bandit will still go out in the winter time. He's more apt to go out for a walk than go out for a bathroom break in the back yard lol. This will be Nala's first winter so we got her the same jacket, but she's still all puppy and has more meat on her bones than Bandit so I'm hoping the cold won't be an issue. I was also considering getting the agility training course things
