We have had Tinkerbell for 8 weeks, since she was 8 weeks old (so she is 18wks now!)
She has never chewed anything in the house, she just pulls out her toys when she wants to sit and chew. In her toy selection there is cloth soft toys, rubber toys, treats, balls (knitted, tennis and fabric)
These seem to keep her mind busy that she looks for nothing else to chew.
