Allowing pets on the bed
As much as a nighttime cuddle with your furry companion is lovely, it’s not the most hygienic activity. There are degrees of hygiene with this one; a freshly washed pooch is more hygienic than a slobbering bundle of mud, but either way the depositing of hair, bacteria, grime etc. onto sheets which are then slept in isn’t the best. Putting down a blanket or moving your cuddles elsewhere is an easy action to prevent such unhygienic practices.
