My Bella is 11 weeks today. I bought her insurance from vpi insurance. 
http://www.my.petinsurance.com/. It is $99 dollars a year and pays pretty good. I think it is definitely worth it when they are puppies. But I don't mind $99.00 a year for any other time. The only things really I see they don't cover is cancer, teeth pulling and spading. I like and my vet was tickled that I had purchased it.
