Urinary tract infection is not a pre-existing condition

We adopted our dog in January. In early February she had a urinary tract infection (UTI) which was proven to have cleared up based on a follow-up urine test. Our pet insurance policy began March 1, and in March she suffered a second, unrelated UTI. Her second UTI was not covered by our pet insurance policy as it was deemed a "pre-existing condition," which is not the case since the first UTI had cleared up and this was a separate incident.
