Flea & Tick Collars: What to Check Before Buying

A collar's convenience is appealing, but the correct product depends on species, sizing, active ingredients, duration and label directions.

Read these five things first

• Species and minimum age/weight
• Active ingredients
• Pests the label addresses
• Expected duration and water-exposure directions
• Fit, removal and adverse-reaction instructions
