Working dogs play a major role in every livestock enterprise in Australia. To get the best out of your dog, it is important they are in peak condition, both inside and out.
Every time we drench, we select for resistant worms as the worms that survive the
drench pass on the resistant genes to their offspring. If we use the same drench
continuously, drench too often or under dose the animals, the number of resistant
worms in the population will increase.
