I'm staying with step son who has a three month old labrador who has been kept inside all the time since owned two months ago. She's fully vaccinated but probably not fully socialized due to early separation from the litter.
I've been taking her for walks and she's happy to stand on ice but when she stops walking I notice her rear is shivering. I gather the breed are cold adapted even with a short coat, and apparently little subcutaneous fat. But it's minus 13 degrees Celsius outside, and since she's shivering, does she need a coat? We don't walk for more than an hour.
