Ticks are an opportunistic pest, and will latch on to you or your pet if you brush past them. It can take a while for a tick to latch on to your dog or cat because of their fur, so it's important to be proactive when it comes to tick control and check your pets regularly.
The last thing you want is to allow one of your pets to bring a tick into your home, and run the risk of an infected tick latching on to you or your family.
