Its been a couple of years since we had a puppy in the house. Our gundogs are kennelled, but only at night. During the day I have been bring the pup in for a couple of hours to make sure he is familiar with normal household goings ons. He was bumbling round the kitchen last night and I was reminded of something I read once- not sure where. It went along the lines of:
"How to punish for puppy chewing.
Keep a rolled-up newspaper handy at all times.
If you see the puppy chewing something it shouldn't, take the rolled up newspaper and bash yourself over the head repeating "I must not leave things out the puppy shouldn't chew"!!!!"
Made me smile anyway
