I need help you guys. My vet told me no toys yet unless they are really tiny and no chew toy because they are too hard but my puppy is trying to chew on everything! Is he teething already at 6 weeks?

I mean, he's biting my fingers, toes, kennel bars, shoe strings, furniture, the rug, and anything else he can get his paws on. Is it okay for me to give him pig ears or toys to chew on? Some of the things he's trying to chew on around the house are much harder than his chew toys or pig ears (which one breeder suggested to me). HELP!!!
