Anything under 75 degrees in Miami is cold. I remember having to buy turtle necks for our dogs when it got cold one year. I grew up there and it was always funny when those few cold days would come and everyone just loved getting their jackets and sweaters out!
Right now it says it's 48 degrees here in Tallahassee. That's rather chilly for this time of year yet. All I know is Zoë isn't adjusting well to the cool weather. She only has 1 sweater right now and if it's cooler than 75 she'll shake until she gets her sweater on. She's also loving being wrapped up in blankets!
