Justin Bieber's has recently made public his struggle with Lyme disease and associated health effects http://theconversation.com/lyme-disease-justin-biebers-tick-bite-illness-can-cause-joint-pain-heart-problems-and-depression-129651. Tick prevention measures remain a sensible precaution for both people and pets enjoying the great outdoors. Dogs infected with Borrelia are sentinels for human infection as dog owners may have also been exposed to the same environments harbouring infected ticks. It is important to emphasise however, that infected dogs do not present a direct risk to people and they can still enjoy a post walk cuddle.
