PUPPY PROBLEMS in MY NEW PUPPY ~

I love my little dog so much & she loves me in return. We have issues though so I thought perhaps some of the doggie owners would advise me as to what to do.

Baby is 7 mos old now. She is a Morky (part Maltese and part Yorki) She still has a few potty problems as she thinks its ok to go poo poo on the floor. But the big problem is that she has made 2 holes in the new carpet of the apt I just moved into! I'm not sure why as she didn't do that before I moved. She has chew bones & lots of toys so I don't know why she is doing this. She's so smart with everything else. Any suggestions?? Hugs Turtle
