Boston Terrier Flea & Tick Guide — When to Start Prevention

Flea and tick risk for Boston Terriers depends on temperature and humidity. Fleas thrive above 46°F; ticks are most active between 40°F and 85°F.

Why Boston Terriers Are More Vulnerable

Fleas become active above 46°F and thrive between 70-85°F with high humidity. Ticks are active at 40°F and peak during spring (April-July). Boston Terriers' coat type allows easier visual tick checks, but prevention is still essential.
