Use vet-approved preventives consistently and check coats after outdoor time.

Ask your vet which preventive fits your region and pet species. Monthly oral or topical products only work when given on schedule.
After hikes, run your fingers through the coat and check ears, armpits, and between toes. Remove ticks carefully with fine tweezers.
Wash bedding regularly and vacuum carpets if you find fleas. Treating the home and all pets together stops reinfestation cycles.
