One handicapping factor that is sometimes overlooked is the “hot kennel” factor. It is a known fact that kennels get hot and, of course, vice versa. There can be many reasons that a kennel may get hot and it seems like all the greyhounds in that kennel run to their peak performance.
One may be that the trainer has wormed the kennel. This is done periodically (more frequently in warm climates) to rid the dogs of parasites that they may have picked up. A lot of times this leads to the greyhounds feeling better and running well. If the kennel had gone flat and then picks up, a lot of the dogs had gone down in grade and, when feeling well again, quickly go back to their proper grade.
Another reason could be a change in feed, or training routine. This will often lead to the greyhounds uptick in performance. I can give you an example of this. I once had a kennel owner running a kennel in Florida ask me to take over his kennel because the greyhounds’ performances had fallen off dramatically. When I went into the kennel, I discovered that the trainer had been giving the greyhounds too many supplements in their feed. The kennel was quiet, and the dogs listless. I immediately changed the feed to strictly meat and meal. Within a week the dogs were more lively and noisy in the kennel. The greyhounds were all down in grade and immediately started winning, and running at their top level. We were the leading kennel, by far, for a few weeks and I had several trainers come and ask me what I was giving the dogs to get them to run so well. I told nothing, I just went back to the basics. The dogs had been given so many supplements that their body chemistry had become toxic.
In conclusion, watch out when kennels get hot, and use that knowledge to improve your chances of picking winners.
