The disease is transmitted by mosquito bites. When a mosquito bites an infected dog, the blood that is drawn contains the parasite in its prelarvar stage. Within the mosquito the parasite develops until its larval stage.
When the mosquito bites a second dog, it transmits the parasite. Already inside the dog, Each heartworm can become a parasite up to 30 centimeters long.

Ticks and babesiosis in dogs
Babesiosis is another disease caused by protozoan (unicellular) parasites of the genus Babesia. Infection in a dog can occur by transmission through tick bites.
There is also direct transmission by blood transfer from dog bites, blood transfusions or transplacental transmission. The incubation period averages approximately two weeks, but the symptoms may remain mild and some cases are not diagnosed for months or years.
