Fleas and ticks are not just biting insects that cause occasional skin irritation for dogs. They can also bring other opportunistic diseases such as Lyme disease and parasitic worms. This is why finding the most effective flea and tick medication is so important for dog owners. The better brands can be on the expensive side, and owners will most likely need a prescription from a veterinarian. However, they will address both the current flea or tick infestation and help to break the cycle that can lead to future issues. Over-the-counter flea and tick medications may not be quite as effective as the prescription brands, but they also help address many of the other conditions a flea or tick infestation can trigger.
