The single most dangerous tick for dogs in Australia is the paralysis tick.
A single female paralysis tick can lay up to 3,000 eggs at a time.
Each female flea can produce up to 40 to 50 eggs a day. That's up to 2,000 in their lifetime.
When a flea jumps onto a pet, it will start feeding within 5 minutes and may suck blood for up to 2½ hours.
