My pets have always been welcome to share sleeping quarters-both my husbands felt the same. My cats sleep on the bed, but my Husky won’t stay on a bed or couch more than a few minutes-I guess it is just too warm for all that fur from hell-she likes her pet bed or a rug...
I had a Lab/ISetter cross who just got too hot trying to sleep with me on the bed. He deliberately slept on the cold, hard tile floor of the bathroom. My Pitador, OTOH, has established permanent Prescirptive Dog Rights to his place on the bed.
