Look, I wrote a book! The first lab I had in the 70's chewed a few shoes (all from different pairs, of course) and we sorted that out, but my last one was an angel. The litters of labs we saw born and sold out of the kennel I worked in never saw the inside of a house from the time they were weaned and out of the whelping box until their new owners took them home. They had individual insulated dog houses inside adjoining fenced kennels with wooden floors. Nothing to chew there, right? Some would chew the doorways of doghouses or even the floor so I was instructed to get a quart of hot sauce and apply to the wood. This dissuaded all but the one "odd dog out". His mum, Taxi, (my old Bogey's mum as well) was known for throwing the odd weird pup and this litter had one. He loved the hot sauce and chewed harder than ever! He was so lonesome and attentive I gave him basic obedience in record time but he was still a bit soft and not really suited for a hunting retriever or field trial dog so we didn't sell him, and my employer gave him to an old man as a companion dog. That litter all had grain names for the registry (as opposed to their home or call names) and I named that little guy Kannata Buckwheat. That was over 20 years ago and I still remember some of the individual dogs that we raised and trained and a few that were brought in for advanced training, either because of their characters or because of particular successes or setbacks in training. I remember having 6 dogs at heel straight out from my left shoulder walking and turning with me, unconnected but intent on my next move, then adding puppies to the file... I didn't make too much cash and had to work long and hard and at first I had to be trained then suppliment that with study, and I probably smelled like a dog but I think that may have been my favourite job. My boss had 300 sheep as well, and a few Border Collies but outside of having to feed the sheep when the boss was away and occasionally slaughter and butcher some lambs for sale the dogs were my main interest.
