chewing problem :l

Hey everyone! I can't wait till Christmas! Bella really needs a new collar and another registration tag because she chewed them both. she has been chewing a lot lately, like about 2 weeks ago, she chewed the couch covers, she didn't do very much damage but mum had to pay $60 to get them fixed because it was the day after my auntie put them on gumtree and said that they were in excellent condition.
