When Trixie Bear was younger she had a thing for our rugs but thank goodness she grew out of it. Only thing I can suggest is to keep saying no when you see it happening. Maybe take the rugs up, LOL
Once in a great while Trix has that look in her eye like she's gonna go for the rug but she looks at me and knows its a NO NO!! Just keep reinforcing that its bad
and hopefully the behavior will stop. Good Luck
