Even if you purchase a lifetime policy for your pet, it might not cover your pet for all illnesses or injuries, or even until his or her death. Many policies have per illness limits or annual limits. In addition, some policies might have limitations on how much the pet is insured for over his or her lifetime.
Above all else, make certain that you check with your insurance agent to ensure that you know all aspects of the policy: benefits, limitations, and restrictions. If there is anything that you do not understand, ask as many questions that you need to fully comprehend everything before you sign anything.
