Dog heartworms are known to occur in?

Dog heartworms, caused by a parasitic worm called Dirofilaria immitis, can affect all breeds of dogs as well as humans, although instances of heartworm infections in humans are quite rare. The transmission of heartworms occurs through mosquito bites, as the larvae are injected into the bloodstream of a host when an infected mosquito feeds.

Since all dog breeds can be exposed to infected mosquitoes, there is no limitation based on size or breed. Additionally, it’s important to note that heartworm disease can occur in both indoor and outdoor dogs, as mosquitoes can enter homes and transmit the disease regardless of the dog's living environment.

Understanding that heartworms do not discriminate based on breed, size, or whether the dogs are kept indoors or outdoors is critical. This reinforces the importance of preventive measures, such as regular veterinary check-ups and administering preventive medication for heartworms to protect all dogs from this serious health threat.
