Typically I insure a dog until about 7 years old, then when the premiums start to go up steeply and/or the co-pay element increases significantly I'd probably cease insurance. I know that the final few years of a dog's life are likely to be expensive, whether that's through severely hiked premiums or just paying directly. I got very frustrated not knowing if a claim would be approved/queried and seeing the insuring entity try to wriggle out of paying (yes, Animal Friends, I'm talking about you) hence relying on the Bank Of LBC.
