Where do fleas lay eggs on dogs? - briefly
Fleas lay their eggs directly on the dog’s coat, primarily where hair meets the skin. The eggs soon detach and fall onto the surrounding environment, such as bedding or flooring.
Where do fleas lay eggs on dogs? - in detail
Fleas deposit their eggs primarily on the host’s coat rather than directly on the skin. The majority of oviposition occurs in areas where the hair is dense and the animal’s body temperature is warm. Typical sites include:
- The base of the spine and neck region, where hair is thick and moisture is higher.
- The tail base and the area surrounding the vent, which provide a sheltered micro‑environment.
- The groin and inner thigh folds, offering protection from external disturbance.
- The armpit and under‑belly regions, where the coat is longer and humidity is greater.
Eggs are loosely attached to individual hairs or to the surrounding debris. They are not firmly anchored; most fall off the dog within hours to days after being laid. Once detached, the eggs drop onto bedding, carpets, or the floor, where they hatch into larvae. Consequently, effective control must address both the animal’s coat and the surrounding environment.
