With more than 850 species of ticks laying 3,000 to 4,000 eggs at a time, ticks can be a real problem for dogs. Once filled with blood, female ticks fall off the host, your dog, and lay eggs. The eggs hatch into larvae, called "seed ticks." There are two life stages of seed ticks.


Seed Ticks

Seed ticks are the larvae of ticks. They have six legs at the first stage of their development. They embed in a host's skin, feed for one to five days, fall to the ground and grow two more legs. Then they look for a second host. The eight-legged seed tick attaches to the second host until fully engorged, a process that takes three to 11 days.


Adult Ticks

Once a host is found, a mature tick feeds until it swells to 10 times its original size. Some males stay on the host up to three years, engorging, mating and repeating the cycle; females engorge, fall off, lay eggs and die. Some species can stay on your dog for three months, others for three years.
