welcome to the world of a retriever!
They are extremely MOUTHY dogs!
You mentioned she is 2 - technically in golden speak she is still a puppy.
My golden wasn't able to be left out of her crate completely until she was over 2 years old. It was about the time she was getting closer to age 3 when she became the almost perfect dog.
Course give her a box of tissues STILL and turn your back and when you turn back around half of them will be ingested the other half in bits and pieces all over the floor!
Maybe your girl just isn't sure what is her's vs your kids.
Try KONG toys. I have had a large RED kong since I had my greyhound and she passed away in 2001. The BLACK ones are for strong aggressive chewers. Look on EBAY.
Good luck..
