Ticks are blood sucking parasites that bite and hold onto the surface of skin to take a blood meal. They like areas of warmth and darkness, so the under the nice fur coat of your pet is a favourite place to be. Aside from being obviously unpleasant to find on your pet, the concern with ticks is the ability they have to transmit diseases such as Lyme disease.
Ticks can be difficult to prevent, and they require that owners take several steps in order to avoid the transmission of diseases. Avoiding areas that have been known to be a reservoir for ticks, such as local areas with long grasses can be one way, but for an active dog at the off-leash park, this may not be possible. It is important to check over your dog once or twice daily if you visit these areas, as it takes a number of hours for a tick to transmit disease after it has bitten. Another important component of the prevention program is medications applied to the skin, or collars, which can greatly decrease the chance that a tick will bite in the first place.
