Hi,
I believe it is worth it. I have insurance through the AKC for both of my labs (ages 4 and 2). The AKC gave me three months coverage free when I registered my dogs, and I chose to renew it after that. The cost for the plan I chose comes to about $350/year per dog. After the policy period deductible of $100, the plan covers 80% of any exams or prescription medication outside of the annual vaccinations and preventive medication such as heartworm pills or frontline. For example it covers ear infections, allergies, diagnostics, x-rays, blood tests, etc. as well as any surgeries. Right now, my four-year-old lad needs surgery for a torn cruciate ligament (sp?) which will be about $2500 to $3000, and insurance will pay 80% of that cost plus any followup visits and pain medication prescribed. They have been very good so far with coverage.
While we hope that our pets won't get injured and we do our best to make sure they are safe, there are some things we just cannot prevent. For that reason, it is worth it to me to have insurance--it gives me the security of knowing that when something like this does happen I will be able to see that they get the very best care possible. And in the meantime, it pays for maintenance medication that I give my dogs for allergies and joint pain.
You may or may not be aware that often the larger the dog the more expensive medication is b/c dosage is by weight. Surgeries can be more expensive for larger dogs, too. Golden retrievers are fairly good sized dogs, so that may also be a factor for your parents.
JMHO

Barbara mentioned VPI, and I have heard good things about them, too. Their website gives you a lot of detail about exactly what they cover and what they don't. There are several plans to choose from. You just need to find a plan that works for you (or your parents).
