Mosquitoes can transmit various diseases to dogs, including heartworm disease, West Nile virus, and Eastern Equine Encephalitis. Heartworm disease is a serious and potentially fatal condition caused by parasitic worms transmitted through mosquito bites. Preventative measures such as monthly heartworm prevention medication are crucial to protect dogs. West Nile virus and Eastern Equine Encephalitis are less common but can also be transmitted to dogs through mosquito bites. To reduce the risk of mosquito-borne diseases, it's essential to use mosquito repellents safe for dogs, avoid outdoor activities during peak mosquito hours, and eliminate standing water where mosquitoes breed.
