Hartz UltraGuard Plus Flea & Tick Collar for Dogs, Medium & Large Breeds, 1 Collar (7-mos. supply)

Editor's note

The tick guide is plain that an over-the-counter collar never replaces a prescribed preventive for a dog that walks in tick habitat. It is a supplement, not the base layer. That is how to read this pick.

The listing claims flea and tick protection for up to 7 months. It is sized for bigger dogs and adjusts to necks up to 22 inches. Talk to your vet about how it fits with any prescription.

A collar does not replace the daily check either. Ticks generally need 24 to 48 hours attached to pass on most infections. After every outdoor session, run your fingers through the coat. Check inside the ears and between the toes.
