Our heater in the house went out won't get fixed until next Monday, and lately, it has been cold here in california, dropping down to about 30-35 degrees at night. Our 6 month old puppy sleeps in the laundry room and I noticed that it gets probably about 5 degrees colder there when the heat is not on. That is the only place where she can sleep where we can close the door so she doesn't neeble on anything when she wakes up. She also chews on the blanket and any shirt that we put on her. Is 30 degrees too cold for a 6 month golden?
