hi tom if I gave my dog a no doz tablet for a trial how long would it take before the caffine is out of his sysytem Hi Bill, Difficult to actually state a specific length of time as the clearance rate for caffeine can vary considerably between individual dogs. The clearance rate also depends on the amount of water ingested, and because greyhounds are notoriously poor water drinkers, its highly likely that the half life, in other words half of the ingested caffeine, could take as long as 8 to 9 hours to clear the system. It could then take another 8 to 9 hours for half of what is left to clear the system and so on. Because caffeine breaks down into several metabolites some of which are excreted very slowly, and because all of the caffeine ingested is excreted in the urine it makes it extremely easy to detect in a urine swab. While you can never be absolutely certain I would be looking at least at 72 hours before racing, and then of course you could have to deal with out of competition swabbing if there was a steward inspection of the kennels and racing greyhounds. The way the situation is in Australia in regard to swabbing both pre and post race as well as out of competition swabbing, using anything that is considered illegal by the racing authorities and which could result in a positive swab is best avoided altogether. Cheers, Tom
