I had a very short, but very bad experience with Veterinary Pet insurance and as a result, I did a LOT of research before I chose pet insurance for Geoffy.
When I took Geoffy for his very first vet checkup I got VPI insurance booklet and decided that I needed to insure him. I had gotten clean bill of health from my ex-vet (note the ex) and I sent the application in ... only to hear back from the VPI that my application was denied because dog has "severe pre-existing conditions" HUH??? That was news to me, they told me he was a glowing picture of health, if a bit thin.
Turned out the vet had been incapable of checking the right boxes - you know, one column "normal," one column "abnormal" - not so hard to check the right box right? Turns out, not right. Vet had checked several things as "abnormal" by mistake, which painted pretty grim picture (abnormal skin was one of the complaints - i knew that at least that one was clearly wrong). Her final conclusion, right after the morbid "abnormals" was "the dog appears in excellent health in every aspect." After I straightened this out with the vet and she called VPI and explained, they still said they'd exclude those (non-existant) conditions, and they would also require a written statement from the vet to even insure Geoff at all. They were pretty rude about it too, implying that I had falsified the vet records. It prompted me do some research, and what I found made me very glad that I did not insure with them.
In my personal opinion, VPI just isn't a very good choice for boxers. It might be a good one for other breeds that have different ailments, and it clearly is very useful if your pet ever gets in an accident, however, if you plan to have it as a general medical insurance, not an accident insurance - not a good choice for a boxer, IMO. For example, they do not cover congenital problems ... so count out the heart, the hips, the elbows ... They will try to claim that anything even remotely connected to those areas is also "congenital." Heart and hips are notariously weak "points" in boxers, and that would be an out-of-pocket expense, whether or not you have VPI. Then, for other expensive the conditions they say they do "cover" ... except that there is a fine print stating that you have to be insured by them for a FULL year before they will cover you. Those include such common things as torn ACL, which costs at the very least 1500 to repair, or 3000 if you choose TPLO (often a better choice for larger breeds).
I've also heard one too many complaints about how they try to bully you into accepting their diagnosis that whatever it is you are complaining must have been pre-existing, even if it is obviously wrong - just try to get you to give up. Since then I've met two people personally who had experience with VPI very similar to what Boxers4life2001 describes.
I ended up insuring Geoffy with Pet Care Pet Insurance:
