Parasite & Tick Prevention for Dogs & Cats

Despite the brutally cold winters we have in Chicago, fleas, ticks, and heartworms should be treated as a year-round problem. Parasites are resilient, especially fleas and ticks, which can go dormant at the first frost and reemerge at the first thaw. Mosquitoes, which are responsible for spreading heartworm disease, can also continue to thrive as long as the temperature is above freezing. Their hardiness and ability to transmit diseases to pets (and sometimes people) is why we recommend constant, year-round parasite & tick prevention for dogs & cats.

Common Diseases Spread by Parasites

Heartworm Disease

Heartworm disease is a serious condition in which heartworm larvae mature into adults while inside your pet and gradually take over the arteries and blood vessels of the heart and lungs. This disease is spread chiefly by female mosquitoes when they feed on an infected animal and then move on to feed on a healthy animal. Clinical signs of this disease include chronic coughing, labored breathing, weakness, inactivity, and collapse. Without treatment, heartworm can be fatal.

Lyme Disease

Ticks are the primary vector of Lyme disease, an illness caused by bacteria called Borrelia burgdorferi. In addition to dogs, Lyme disease can also affect humans, but it can only be passed on to them from a tick bite. Signs your pet may have Lyme disease include fever, lethargy, swollen joints, and lameness. Lyme disease is treatable, but you can also protect your canine by having them receive the Lyme vaccine.

Flea Allergy Dermatitis

Being a snack for fleas is certainly not comfortable, and many pets can actually have an allergic reaction to flea bites. This is due to a chemical in the flea’s saliva, to which some animals are hypersensitive. This can lead to very severe itching and scratching, a damaged skin barrier, and secondary skin infections. Flea prevention is a must for eradicating infestations, and other treatments are necessary for treating allergies, inflammation, and itching.
