Why Do Dogs Need Deworming in Winter?

1. Many pet owners might mistakenly believe that during the cold winter months, the low temperatures would naturally kill off parasites, rendering them unnecessary to treat their pets. Conversely, they might think that since summer is hot and conducive to the proliferation of parasites, it's only then that dogs should be dewormed. However, this line of thinking is fundamentally flawed. Take fleas, for instance. While it's true that fleas are less active in winter, this does not mean they vanish entirely. Fleas undergo a "fourstage metamorphosis" involving eggs, larvae, pupae, and adults, each requiring different types of food at various stages. This allows them to survive in extreme weather conditions. From November to March, when temperatures are low, flea larvae can remain dormant within pupae until the weather warms up to continue their development. The larvae do not need to feed on blood; they can survive on the feces of adult fleas or various organic debris. If a dog is not bathed during the winter, these larvae can potentially hide on the pet and survive the entire season. Therefore, skipping deworming in winter can lead to a flea infestation in the home by spring.

2. Most ticks also do not perish during the winter due to cold temperatures; they may hide in dog beds or rooms, waiting for warmer weather to emerge and seek hosts. Heartworms, on the other hand, are primarily transmitted by mosquitoes. Many people assume there are no mosquitoes in winter, but this is not the case. Heartworms can become active within mosquitoes when temperatures remain above 13°C for three consecutive days, preparing to find new hosts.

3. Therefore, pet owners should not take deworming lightly, even during the chill of winter. While summer is indeed the peak season for parasites, it is crucial to maintain yearround prevention to ensure the health of your furry friend.

It's also important to keep your dog clean during the winter. Aim to bathe them once a month, avoid taking them out during rain or snow, and protect their paw pads to prevent frostbite or injury. Should you have any further questions, don't hesitate to consult with an online veterinary expert.
