Love the booties!!
I try to get them on Charlie, my poodle, quite the task!!!
When I do he starts the infamous 'duck walk'.
If it's under 20 degrees outside he will stop walking and I have to go and pick him up. It takes him a few minutes once inside to warm his feet.
I'm thinking because when he's groomed he gets his nails clipped and that puts his nail nerves right into the frost.
He'll be walking, slower, slower, stop!
