Frequently asked questions
When does flea season start in Santa Fe?
Around early April in a typical year, once local averages hold around 50°F. A warm spring pulls it earlier — prevention shouldn't wait for the calendar.

Do dogs in Santa Fe need prevention outside flea season?
Yes — vets recommend year-round parasite prevention regardless of the local calendar. Indoor fleas ignore the weather entirely, and ticks in New Mexico are typically active late January to mid-December, a longer window than fleas get.
