Can I ask a possibly silly question? We've had our new dog 5 year old greyhound for a month - he's lovely, very good-natured if shy (but improving by the day - we had our first proper tail wag this week!)
Tomorrow I need to drop the dcs at school at 830, go for a walk for half an hour with the dog then get my food shopping (will take an hour tops). Then pick up dcs at 1130. I haven't enough time to get home and drop him off before I go shopping (the supermarket is 12 miles from home but nearer school) and don't want to leave him home alone for 4 hours (8 to 12).
Would he be safe in the car for the hour I go shopping in a supermarket car park? I'd never leave him if it was anywhere near warm weather, but in this cold would it be cruel? I don't think he'd be distressed he's quite happy curled up in the boot, but I've never left him for more than 10 minutes before.
