I have six rescue dogs that I have insured with Pets Best for several years. This last month, Pets Best raised my rate from $165.54 per month to $361.80 per month (an increase of $198 per month - more than double my previous payment). When I noticed the payment amount on my credit card statement, I called Pets Best immediately and told them I simply couldn't afford it. We then changed the policy so that it included a $500 deductible on each dog with a charge of $226.84 per month. It was my understanding that Pets Best would refund me the difference. The difference between the two prices was $134.96. The refund they provided was $14.37. I am unhappy in the extreme about the overwhelming and sudden rate increase. I am further really unhappy that Pets Best did not refund me the difference after I changed the plan. My recommendation is to not insure your animal with Pets Best unless you want to look forward to this kind of surprise rate increase when it is too late to insure your pets with a different insurance company. I note that the email message they sent regarding my policy renewal had a very mild statement that I might notice a rate change.
