Typically yes, but maybe someone else can verify for this company? I looked into it way back when I learned of pet insurance, but at the time, my dogs were 4, 5, 6 respectively. the cost to insure my 6 year old was MORE per year than I had ever spent in a year on his bills, even with an emergency trip once a year. so DEFINITELY sign up when they are young puppies! Not to mention they can be quick to call anything a 'pre-existing' condition.
