Vets bills. Our dog has an intermittent cough like he's trying to clear his throat & it only seems to happen in spring & summer, started last year & has come back this year. He seems to be perfectly fine apart from his cough, is full of energy and not off his food. Last year he had 6 or 7 x-rays which showed nothing & this year the vet thinks they should do a ct scan & some other tests including putting a probe down into his lungs which will cost us £4k and again may show nothing but if it does & he needs any additional surgery we could be looking at another £4k+. He is insured but it wouldn't fully cover the initial scan. We don't know what to do especially if like last year the cough disappears in the autumn
