Place the collar around the animal’s neck, leaving space for two fingers between the collar and the skin, then lock the fastener as directed by the manufacturer. Re‑check the fit periodically to maintain proper tightness.
How should a flea collar be fastened? - in detail
A flea collar must be placed snugly around the animal’s neck without compressing the skin. Begin by measuring the circumference of the neck with a flexible tape; the collar’s length should be 1‑2 cm longer than this measurement to allow adjustment. Slide the collar over the head, positioning the active side (usually marked) against the skin, typically at the base of the neck where the fur is shortest.
Fasten the collar using its built‑in clasp, snap‑lock, or Velcro strip. Ensure the closure is secure but not overly tight: you should be able to slide one or two fingers between the collar and the skin. After fastening, rotate the collar 360° to confirm it sits evenly and does not twist.
Inspect the fit daily for signs of irritation, swelling, or slipping. If the animal can easily remove the collar, replace it with a larger size or adjust the fastening mechanism.
When the collar reaches the end of its recommended wear period, discard it according to manufacturer instructions to avoid reduced efficacy or chemical exposure.
Following these steps guarantees proper placement, maximizes flea control, and minimizes risk of injury.
