It's my experience that pugs love to lick. Fabric especially but also people, other pets and even themselves. Ickis, being half chihuahua seems to have missed out on the licking gene but Pearl and Tank are addicts. Pearl especially so.
Pearl is still adjusting to the time change and therefore is waking up about an hour before the alarm goes off. I try and ignore her, hoping that she will lay back down and go back to sleep. It happens occasionally. This morning though she spent most of that extra hour licking the bedspread; the sound of it was rather soothing and I lapsed in and out of sleep until the alarm sounded. If that keeps her occupied and allows me to get a little bit more sleep then hey, I'm all for it.
I think Hubby might be of another opinion though after he rolled over and into 'the wet spot' and about shot out of bed thinking someone had peed. Oops!
