Dogs typically contract Lyme disease primarily through a tick bite. The disease is caused by the bacterium Borrelia burgdorferi, which is transmitted to dogs when they are bitten by infected black-legged ticks, commonly known as deer ticks. These ticks feed on the blood of mammals, and when they attach to a dog, they can introduce the bacteria into the dog's bloodstream.

Understanding this method of transmission is crucial for preventing Lyme disease in dogs. Regular checking for ticks after outdoor activities, especially in wooded or grassy areas, is an effective preventive measure. By promptly removing any ticks, the risk of infection can be significantly reduced, as the ticks must be attached for a certain period before transmitting the disease.

The other potential options do not play a role in the transmission of Lyme disease to dogs. Contaminated food, infected water sources, and direct contact with infected animals do not facilitate the transfer of the bacteria that cause Lyme disease. Thus, awareness of the tick's role in the transmission of Lyme disease is vital for dog owners to ensure the health and well-being of their pets.
