Are there seasons when dogs are at greater risk of becoming infected?
In most areas of the country, people and their pets are at a moderate to high risk of exposure from April to November. Ticks are most active during these months and people and their pets are spending more time enjoying outdoor activities, but disease onset can occur at any time of the year. Lyme disease transmission is a high concern in both spring and fall. In spring, deer ticks must feed to progress from larvae to nymphs—and then again—to mature into adult ticks.
