I currently have two dogs that have Petshealth Insurance, and will always keep them insured. My last two great dogs cost me thousands of dollars, so I purchased plans for the current two when they were pups. True, not every year I break even, but I know they are covered and that's a feeling. One ingested 42 earplugs a little over a year ago, and the reimbursement for that incident alone will pay for his insurance for more than two years.
Information and payment has always been timely.
One thing...it would be nice to have a "reasonable cost" chart. My vet is very careful with costs, and it always surprises me when I am only partially reimbursed, even for vaccines. Having the information before treatment would take out the surprise factor, and may help with disappoinment for all of your clients.
