Regular topical application of specially formulated insecticides helps to prevent a dog from getting ticks. Controlling the presence of ticks in the dog's environment is also helpful.
Topical insecticides applied monthly to the fur on the dog's upper back is the easiest and most effective way to keep ticks off a dog. They also provide the longest period of protection. Revolution and Frontline are two examples of commercial treatments. Sprays, powders and dips that contain tick-repelling chemicals are sometimes useful, but it important to avoid getting these in the eyes, ears or nose of the dog. Shampoos are mainly helpful in removing ticks that are already on the pet, though some also offer a small amount of protection. A flea and tick collar is another option, but proper application is essential to ensure that the dog does not chew on the collar. Some collars are no longer effective once they get wet.
Clearing yard and kennel areas of leaves, brush and tall grass creates an environment that is less friendly to ticks. Taking measures to keep the area free of rodents, deer and other animals that carry ticks also helps. It is important to check the dog daily for any ticks that may have become attached despite precautionary measures and remove any ticks promptly.
