Constant barking is driving me nuts

Around the middle of May my buddy and I purchased a new puppy.

I should say my buddy and I adopted it from a local shelter but it cost as much as one from a breeder so I view it as a purchase.

Roxey is a small poodle mix and is smart as a whip most of the time. The kids just prefer his and he adores them as well, then as the temperatures are turning colder now my buddy and I have begun to worry about taking his outside. She is just a tiny thing and I fear that he will be too cold. She did do something funny the other afternoon that made us laugh though, he started barking at the heat register. My superb friend and I laughed at first I should say because each time the heat came on he would run to the register and start barking again, then you see, the registers make a clicking noise as the warm water starts to run through them. Roxey must feel that something is in there because he barks to try and get it to go away, however i have tried kneeling on the floor next to the register and assuring his that all is well but he just doesn’t see it that way. My superb friend and I have started ignoring the barking and praising the quiet so that he will learn that it is better to be silent. I even put a blanket next to the register hoping that he will prefer kneeling next to the heat it provides, and the constant need to bark has to stop soon. Eventually he will get used to this new noise and I hope it is sooner rather than later.
