What age is she? What toys have you got her that she can chew safely? A toy that you can stuff with treats is useful - if she's teething a kong toy stuffed with kibble mixed with a little plain yoghurt would help her gums and hopefully keep her occupied for a reasonable length of time.
Don't give her plastic bottles, few soft toys designed for puppies and a puppy king with some of her food in. There are loads of puppy toys available dont give household stuff unless u want pup to grow up and think its for her to chew. Labs are notorious chewers!
I'd go for something super smelly, like sardines or pilchards, mixed with her kibble in a kong to get her interested and then actually hold it and encourage her to get stuck in. You often have to teach them how to use a kong, either by holding it while they lick it out or throwing and bouncing it so the contents fall out.
The other thing my pup loves is his split antler, the whole ones are too tough for puppy teeth, but they can scrape the marrow out of the split ones without damaging their teeth.
