Pathogens and Life Cycle — Understanding the Basics to Enhance Flea Treatment for Dogs

Throughout their lifecycle, fleas spend most of their time off the dog’s body. Being light-sensitive, they typically hide in bedding materials or floor cracks, only parasitizing the dog when feeding or laying eggs. A single female flea can lay 100–200 eggs. Flea eggs are oval-shaped with pointed ends, white, and extremely small—difficult to see with the naked eye. As dogs move, these eggs can fall off, spreading throughout the dog’s living areas. The development from egg to adult flea takes approximately 21 days, though this period may lengthen in colder climates. Newly hatched fleas can survive for weeks without feeding, lying in wait for a dog. Understanding the flea life cycle helps us develop more precise flea treatment plans for dogs, improving treatment effectiveness.
