The soft, warm fur of dogs and cats provides the perfect environment for fleas and ticks. These insects feed on your pet’s blood and can cause health problems ranging from allergic reactions to serious tick-borne illnesses. Fleas are small, wingless insects that live on animals and feed off their blood. Ticks are much larger than fleas, and they have eight legs instead of six. They also have piercing mouthparts that allow them to inject their saliva into the animal's skin. Both fleas and ticks can carry diseases and be harmful to you and your family!
