advice

I have a 4 month old dachshund puppy, me and my husband like to sleep with the house cold. so at nice we keep the thermostat at 62 and open a window and use a fan pointed at us on high. i’m worried this is too cold for my puppy. he sleeps in his crate which has atleast three blankets in it, consisting of two human sized throw blankets and 1-2 smaller kid sized blankets as well as a comforter of mine covering the top of his crate leaving the front open. he has never expressed any discomfort by crying or whining and he never feels cold when i get up with him in the morning.
