teething problems

We had this problem last year with stig he was a nightmare in the end we used Time out. we used to yelp but when it didn't work we shut him in the kitchen on his own, sometimes we had to put him staight back time and time again. Sometimes I couldn't walk across the room with out a nipping puppy hanging of my leg. It will get better once his teeth start to come in. Have you also tried a Kong which you can fill with treats and put in freezer or fridge so they are cold like a baby's teething ring. We got ringo a puppy one Stig has a big boys one now. he loved it yesterday. Stig likes it filled with Natural yoghurt mixed with Tuna( In Oil not Brine),or Chicken, meat and some garlic, When you get out the freezer let it defrost for 20-30 mins.
