Lately,Sally my Lurcher will leave her usual position of being curled up on the sofa,and stretch out on the floor by the radiator. Sighthounds are not really floor-sleepers as their boney bodies need softness under them.
She does have a fleece 'housecoat' that she wears...but I wonder if she is seeking warmth from the radiator,or just a change of position?
Now - that is what I would call girly. The one on Pete's dog seems to warm the underside of the dog too - the 'normal' dog coats seem to just cover their backs.
My last dog used to get iced up pads, he would just stand their with the relevant paw in the air waiting for me to de-ice him. If he was still around he would be wearing boots.
Our Wolfhounds (sight-hounds) are sleeping beside the fire on the floor in this cold weather and they have a double bed in the lounge for them to sleep on.
we have thick rugs beside the fire but you could just put some blankets down for her to lie on.
