Hi all. Want advice as I think I am not being unusual but DD says I am. Just joined after a while of lurking
I think the great detective skills of Mumsnet will be able to help me out!
I recently purchased a set of expensive paintbrushes for my DD's art GCSE. They work wonderfully and appeared to be very stable.
Yesterday, I asked my daughter about how her art is going, and if the brushes are any good. She seemed nervous of something and tried to avoid talking about it. So, I went to check her pencil case.
And, to my horror, I saw that the brushes were chewed down and covered in a substance that looked like saliva 
I am very upset. We own a dog, who I at first thought was the culprit, but upon some quick thinking I realised that he would not be able to reach the pencil case. Asking my daughter, she denied it all and said they were like that before!!
Well, if they had came like that, I would not have given them to her!
Mumsnet, please help me to solve the mystery of...
Who ate my daughter's paintbrushes?
