TFT Heat in home

Question
I am getting a puppy TFT and I know that they don't like the cold but at what temp. should I keep my home. I work and want my puppy to be comfortable.

Answer
I am assuming as in TFT you are meaning a Toy Fox Terrier.  Don't let the lack of coat fool you.  They are rather hearty dogs.  If you are cold most likely they will be also.  If you are warm they will be too.  Remember these are little ratters.  Thus they have to be hearty enough to do work in barns.  Barns are not always heated.  

Hope this helps.....
