Parasites pose year-round threat to pets, experts warn

The notion that pets are safe from parasites during colder months is a dangerous myth, according to experts. Fleas and ticks, along with internal parasites, do not hibernate and can thrive year-round, especially in heated homes and increasingly mild climates.

Many fleas complete their life cycles indoors, surviving on carpets, furniture, and bedding where household warmth and humidity provide ideal conditions. In regions with temperate winters, ticks can remain active for extended periods, posing a constant threat. Furthermore, human travel, visits to parks, or interactions with other animals can easily introduce these unwelcome guests into a pet's environment.

Preventing parasite infestations requires a two-pronged approach: external treatments targeting fleas, ticks, and some mites, and internal treatments for intestinal worms and tapeworms. These parasites can cause various health issues, from skin irritation and anemia to the transmission of serious diseases. Some internal parasites, like those causing heartworm, are a significant concern in areas with year-round mosquito activity.

Even indoor-only pets are not entirely immune. Parasite eggs or larvae can be tracked inside on shoes, clothing, or bags, or brought in by other pets that venture outdoors. For dogs, contact with grass, soil, or contaminated puddles during walks increases the risk of intestinal parasites. Experts emphasize that deworming schedules should be tailored to each pet's specific lifestyle, environment, and health needs, rather than relying on a universal calendar.
