Despite popular belief, protecting dogs and cats from parasites requires a year-round commitment. While fleas, ticks, mosquitoes, and other pests are known to be more persistent in warmer climates, they don’t disappear when the temperature drops. Opting to skip preventive treatments when it’s wintertime could have long-term negative consequences for your pet.

Fleas and ticks strive in warmer climates, however they can survive year-round. They bite your pet and suck their blood causing them to be itchy and highly uncomfortable. When left untreated the bite can lead to many health issues and disease transmission.


When left unchecked a flea bite can cause lethargy, weakness, allergic dermatitis, tapeworms and even death if not caught and treated in time. Even when it gets cold outside, the perfect environment for fleas is your home. If your pet has fleas there is also a high chance that you may be encountered with an infestation in your house which could be difficult to get rid of.


Found anywhere in the United States and at any time of the year, ticks can also transmit several debilitating disease in dogs, such as Lyme disease, anaplasmosis, tick paralysis, and Rocky Mountain spotted fever.


Mosquitos are known to transmit microscopic worms from an infected animal to another. Heartworms mature and live in the heart and large blood vessels of the lungs leading to infection. The infection could affect blood flow and impact the internal organs, including the heart, lungs, and liver, severely weakening and even leading to death. All it takes is one mosquito bite to infect an animal with heartworm disease, so continuous protection is the best defense.
